Is your air filter housing sealing correctly?

Read entire post: Is your air filter housing sealing correctly?

 

Air Filter

 

Many modern vehicles use a panel style air filter for cleaning the outside air your vehicle's engine breathes.

 

Panel filters are not the most robust of designs and when a vehicle is working under hot conditions (not uncommon here in Australia) the housing can slightly distort.

 

This ever so slight distortion can compromise the amount of clamping force it provides on the filter element allowing air to move past or around the filter rather than through it.

 

Dust or any fine particles can cause catastrophic damage to an engineEven small quantities can significantly reduce its life span.

 

Its the same for oil and fuel filters as well as air.

 

Today's engines have sensors in the intake measuring things like airflow and/or pressure.

 

Dust collecting on these can cause faulty readings which can cause the engine's computer (ECU) to think there an actual fault - technically there is!

 

The vehicle may go into 'limp mode' in an attempt to prevent or minimise damage.

 

Not a great experience if you are a long way from home on a dusty dirt track.

 

A housing that holds barrel or drum type filter as found on heavy earth moving equipment provides much better clamping force to handle those more extreme conditions

 

There are a number of reasons why barrel-style filters are not commonly used.

 

The complexity of modern engines does not provide much available space to install a larger barrel-style filter.

 

Cost is also a significant factor, generally panel filters are less expensive than barrel types.

 

So you have a panel type filter fitted and while you're doing a routine service you notice fine dust on the engine side (the 'clean' side) of the filter.

 

We know filters play a critical role in maintaining a healthy engine, even more, important for turbocharged vehicles - what should you do?

 

If you own a Toyota Land Cruiser 70 Series VDJ (V8 4.5L turbo diesel) or a Land Cruiser Prado 120/150 Series KZJ KDJ RZJ (4 Cyl 3.0L turbo diesel or 2.7L Petrol) we have a solution for you, the new air filter housing shim kit designed by Terrain Tamer

 

TTAFSK__1

 

 

  • The kit includes a custom-designed shim along with a new Terrain Tamer branded air filter
  • It increases the clamping force the upper and lower sections of the air filter housing has on the filter element creating a more secure seal
  • All Terrain Tamer designed parts (including filters) are designed to meet or exceed OEM specifications
  • The shim itself is cut from approx 0.7mm stainless steel plate
  • It is designed to be installed into the sealing channel in the upper section of the housing
  • An adhesive like Sikaflex Pro is recommended to be used to secure the shim in place although it is not required

Which 4x4 accessories and modifications do you really need?

Read entire post: Which 4x4 accessories and modifications do you really need?

 

2_All-4-Adventure-Canopy-Package-4.5

 

Today we are going to talk about which 4x4 accessories or 4wd modifications you should consider essential "must-have" or "would be nice to have" 

 

After all, with so many products in the market, it can be tricky to differentiate essential to not-so essential accessories.

 

Let's start from the basics:

 


- An accessory is usually something not permanently attached to the vehicle, like a fridge, or not directly related to vehicle fitments, such as an electric winch. 

 

- A modification is usually the process of replacing an existing part of the vehicle, like tyres or suspension. 


 

We used the expression "usually" because there could be countless interpretations based on who you ask. 

 

Still, it's fair saying that certain products are must-haves if, for example, you are planning an offroad trip with your family.

 

Let's split them into the two sections mentioned earlier:

 

 

THE ESSENTIAL MUST-HAVE 4WD ACCESSORIES / MODIFICATIONS

 

 

 

Recovery Gear

 

allfourx4_-_recovery_gear

 

A common approach from novice 4wdrivers is to look at aesthetics first and purchase a sexy looking lift kit thinking it as a must-have to go offroad. 

 

Admittingly they can be much more desirable than let's say a cargo-barrier, a fire extinguisher, radios, or first aid kits.

 

However let's make this clear: purchase the safety equipment firstYou won't regret it for when you may need it. 

 

There are several types of 4wd recovery gear products designed for different recovery situations, and the following lists some of the most popular. 

 

You don't need to have them all but make sure you carry some suitable for the offroad environment you are travelling to.

 

These includes:

 

 

Recovery Points:

 

RATED_RECOVERY_POINTS

 

If you get bogged, one way to rescue your vehicle is being pulled with tremendous force. 

 

You need a mounting point for that force.

 

Don't think that any hook you find in your car will do the job. 

 

Some of those hooks are just tie-downs, designed to stop the vehicle moving when being transported.

 

The forces involved in vehicle recoveries are much stronger and can rip these tie-down hooks off the vehicle (and that can be very dangerous).

 

In the front of your car, a couple of recovery points will be convenient.

 

In the rear, you potentially could use a towbar as a recovery point, provided that they are secured to the chassis of the vehicle. 

 

Sure you may bend the tow hitch, but tests show it takes approx. 10 Tonnes of effort, by which time, you'll probably have broken the snatch strap wrapped to it. 

 

By the way, do not ever use the tow-ball as a recovery point.

 


 

 

Snatch Straps

 

snatch_straps_all_four_x_4_spares

 

One of the cheapest and most useful items of recovery gear. Although not the safest if misused.

 

A snatch strap is a giant elastic band made in nylon that can stretch 20 to 30% that attaches to the stuck vehicle on one end and the other end to the recovery vehicle which uses momentum to pull the stuck vehicle free.

 

Be wary of the ratings. The rating of a snatch strap is the load at which it's designed to break, and they can vary between 6000Kg and 12000Kg.

 


 

 

Car Jacks

 

Car_Jack_all_four_x_4_spares

 

You should already carry your vehicle standard jack at all times, so that's one less piece of recovery gear to worry about. 

 

However, depending on where you get stuck, that won't be much of a help.

 

That is why there are several other types of jacks, each suited to different terrains.

 


 

 

Air jacks (or Exhaust Jacks)

 

exhaust_jack

 

An air jack or also called exhaust jack is a big balloon perfect for sand and soft ground recoveries. You put the deflated air jack underneath your stuck vehicle, connect its input hose to the exhaust and this inflates the bag and lift the car.

 


 

 

Hi-Lift Jacks

 

hi_lift_jack_all_four_x_4

 

They can lift to three Tons vehicles about a meter, and they can also be used for winching and bead breaking.

 

Hi-lift jacks are great for when you need to lift the car a long way, like when you need to stack rocks under a wheel or cannot get under the body to lift. 

 

The biggest cons of hi-lift jacks are finding a place on the car actually to mount it. 

 

They can only work on the body of the vehicle not under the chassis like the regular car jack. 

 

So not every vehicle have places where a hi-lift jack can be used. 

 

In some instances, a bull bar can be used, but not always, or strong rock slider sidesteps, or metal rear bumpers.

 


 

Car Jack VS Air Jack VS Hi-Lift Jack

 

Here is a comparison table across these three types of recovery jacks

 

  Car Jack Air Jack Hi-Lift Jack
Approximate Cost Included with car $250 $100
Soft ground With a flat plate Excellent With a flat plate
Rocky ground Yes with care Yes
Suitable for modern vehicles Yes Yes Rarely, few jacking points
Height Approx. 30 cm Up to Approx 50cm One metre
Other uses None None Winch, bread breaking, panel bending and more uses

 

 


 

 

TRACTION DEVICES

 

The purpose of traction devices is to improve grip, increase clearance, reduce axle flex to put more weight on the wheels and create a ramp.

 

Since you place them under the wheels, you could potentially use rocks, wood sticks or car mats in case of need, however, there are several great specifically made products designed to recover your car. 

 

Let's go thought some of them:

 

Flexible traction mats

 

flexible_traction_mats

 

They are light devices with linked tracks and work best in soft surfaces. Easy to transport as they are roll-up nice and tight.

 


 

Bridging ramps

 

bridging_ramps

 

These are heavy and bulky to carry around, but they can be used on any surfaces. They can take the weight of a vehicle's wheel across a gap or can also be jammed under the wheels to create a ramp.

 


 

Traction ramps

 

treds 4x4

 

Similar to bridging ramps but they are much lighter and can only be used on soft surfaces. They are quite a popular recovery and extraction devices and can come in different colours.

 


 

Inflatable traction aids

 

inflatable_Traction_ramps

 

These are like traction ramps but inflatable. They are light and small and can only fill in gaps. 

 

They don't provide the sort of flotation a traction ramp can achieve, but they are better than a flexible traction mat. 

 

The great thing is that they can be used on any surfaces.

 


 

Axes

 

axes,_shovels

 

These are not essential recovery devices, but if you drive through thick bush and come across fallen trees blocking your way, you would be glad to have brought one of these with you. A saw and chainsaw will work best, though.

 


 

Spades and shovels

 

spades_shovels

 

The universal pieces of recovery.

 

The spade is not as efficient as the shovel for moving loose dirt, but it's far superior for digging.

 

Shovels are super convenient in the sand. Ideally carry both or get a multifunction tool with different heads for picks, shovels, spade and axes.

 



 

Fire extinguishers and fire blankets

 

fire_estinguisher

 

We hope you never come across a vehicle on fire, it's not a pretty sight, but in the event you do, a fire extinguisher will save lives, vehicles and potential bush fires. 

 

If you drive through a powder extinguisher will be the best choice for dry grass catching fire. 

 

For vehicle fires, you will need an electrical extinguisher. 

 

If your cooking oil on the BBQ catches fire, then a fire blanket will do the job.

 


 

 

First Aid kits and Survival Kits

 

first_aid_survival_kit

 

These are top priorities to always carry with you while travelling anywhere remote. 

 

The first aid kit should include infection control items, saline to clean eyes or wounds, bandages, gauze, dressings, burns sheet, sharp scissors and more. 

 

Survival kits should automatically include a small first aid kit. On top of that, they should consist of a swiss army knife, notepad and pencil, hand-powered torch, flint, newspaper, compass, thermal blankets, fishing wire, water purification tablets, whistle and gloves.

 


 

Cargo Barriers

 

milford_cargo_barrier

 

These metal mesh cargo barriers fit between the rear of the vehicle and its occupants. They are handy to stop the contents of the rear flying forwards and injuring someone in case of a crash.

 

They also make it easier to store items in the rear storage compartment. As a bonus, a cargo barrier can act as a rollover cage preventing deformation of the cabin.

 


 

Internal Storage Systems

 

msa_4x4_internal_storage

 

You can convert the back of your vehicle into a full organized vehicle storage system maximizing the available space right to the top of the back of your car.

 

A set of shelves, trays and single or double drawers will subdivide the space in the back, giving you easier access to get things in and out without removing lots of gear.

 

And you can also have your fridge bolted on fridge drop slides allowing easier access.

 


 

Tyres

 

offroad_tyres

 

To go offroad, you'll need offroad tyres. It may sound obvious, but it's not.

 

The standard tyres on a 4wd vehicle are passenger tyres, and they are only designed for road use. They provide insufficient grip and will puncture too easily. 

 

You should consider swapping your tyres to light truck construction tyres with at least an all-terrain tread pattern. 

 

You should be ok if you have a dual cab ute that should have tyres designed for a load, but if you have low profile tyres, you should swap them before going bush.

 


 

Suspension

 

Terrain-Tamer-Suspension


Similarly to tyres, standard 4wd suspension are not designed to have the vehicle be loaded up and driven offroad. 

 

Manufacturers don't spend money providing heavy-duty quality suspension on stock vehicles. If you do light-duty offroading with a small load and don't venture into the outback, then the standard suspension will be adequate.

 

If you need to load bigger weights and travel to the outback, then a small suspension lift kit would be highly advisable. 

 

A suspension upgrade is very important for safety and transforms a loaded vehicle when offroad or on dirt roads, and particularly when towing. 

 

You can also increase your vehicle GVM (gross vehicle mass) by upgrading your suspensions.

 

A typical aftermarket kit could be made of four springs and shocks with a lift of approximately two inches.

 


 

Tools

 

4x4-toolbox_kit

 

Carrying basic essential tool kits on your trip will be highly recommended in the event you need to fix or modify a broken part.

 

Tools to take with you include shifting spanners, flat and Philips head screwdrivers, knives, socket set, pliers, hacksaw, hammers, multimeter, mole wrenches, wheel braces.

 

You can also add workshop manuals, cable ties, fuses, electrical wires, hose clams, thread-locks, wd-40, jump leads, nuts, bolts, screws, emergency windscreen, tyre repair kits, Allen keys.

 


 

Spare Parts

 

spares_parts_offroad_trip


The spare parts you decide to take with you will depend on the vehicle and the trip.

 

Usually, if you are considering a long trip, you could be taking with you some spare: air and fuel filters, extra spare tyres, hoses, belts, electrical wires, fuses, screws, nuts, bolts, rags, light globes, thread lock, cable ties, superglue, wd-40 and a workshop manual.

 


 

Air Compressor

 

mean mother air compressor


An absolute must.

 

You will need to reinflate your tyres after dropping pressures or to reseat a tyre or rim after it comes off.

 

Air compressors can be permanently mounted to the vehicle (like under the bonnet) or be portable.


Most compressors are electric at 12V, but there are quicker ones driven by the engine.

 


 

Uhf Radio

 

oricom_4x4-uhf


Driving with others is probably much more fun and safer..if you can communicate easily.

 

But there would be times where you need to communicate with people outside your group.

 

UHF CB Radios work by having a set of CB frequencies available for public use. No licence or fees, totally free.

 

Radio units can be vehicle mounted with a range for up to 40Km or handheld usually up to 5km.


A typical mix of types of communication available for touring offroad is UHF Radios to communicate with others in the same group, UHF and HF radio to communicate with other groups, HF Radio and satellite phones to communicate with anyone in the world. 

 


 


THE WOULD-BE NICE HAVING LIST OF 4WD ACCESSORIES / MODS

 

Items in this category are debatable wether should be essential or not based on who you ask; however, usually that includes:

 

 

Snorkels

 

Safari-Snorkel-all_four_x_4

 

Waterproofed relocated air intake that only allows air through the intake.

 

The main job of 4wd snorkels is to prevent water from going to the engine and by fitting a snorkel to your vehicle means the air intake is very much higher than it was before. So if you decide to cross a deep river, you have more height tolerance not to let water going to the engine.

 

Other benefits of a snorkel are cleaner air and improved performance, especially in older diesel vehicles.

 


 

Breathers

 

Breathers_blackhawk


Breathers are a set of pipes which allow air inside the diffs and other components to breath.

 

The diff can breathe through a long pipe, usually routed to the top of the engine compartment.

 

A breather kit is an excellent mod to have in situations like water crossing where hot diffs get in contact with cold water, and due to inadequate lubrication, they will eventually get damaged.

 


 

Water Storage

 

water_storage_tanks


If you make a big trip to the outback, you may need extra water.

 

So transporting extra water tanks is a smart idea.

 

They come in all sorts of shapes and sizes and/or you could customize them to live inside or outside your vehicle.

 

Make sure to use only food-grade hoses for the drinking tank plus a second tank for greywater.

 


 

Fridge

 

ironman_4x4_fridge


A small fridge of approx 20 to 60L capacity is not a real necessity, but kind of is when you are in the outback sun at 45degrees.

 

You can fit all your trip's cheese, drinks, dairy food fresh and cool, making your life much more comfortable.

 

Fridges must be adequately secured in the vehicle, and drop fridge slides are the best set up to do so with easier access from the rear of your car.

 

Fridges need electrical power, and we do not recommend plugging them into the rear 12V socket.

 

You will probably need a dual battery system for an alternative power supply.

 


 

Long Range Fuel Tanks

 

brown_davis_long_range_fuel_tank


To drive further with fewer fuel stops.

 

If you plan a big trip to the outback, you will want to carry extra fuel.

 

Long-range fuel tanks can be replacements and/or additional fuel tanks.

 

There are two basics types of long range fuel tanks, replacement and auxiliary.

 

Replacement tanks will be "replacing" your stock tank with one the has a larger capacity.

 

Auxiliary tanks are additional separate tanks.

 


 

Bash Plates (underbody protection)

 

underbody_protection_bash_plates


These underbody protection metal plates will protect components such as the transfer case, fuel tank and diffs.

 

Going offroad will always put you at risk of running out of clearance and bash plates will absorb the impact from terrain shielding it from the expensive transmission.

 

Most stock 4wd vehicles don't come with suitable underbody protection bash plates, so you need to provide a stronger aftermarket alternative.

 


 

Bull Bars

 

All_Four_x_4_Spares_-_79_Series_2019-8_m-_edited


Originally the only intent of bull bars was to provide either a replacement or supplementary bumper bar to protect the vehicle in the event of a collision with animals.

 

Nowadays other than the original purpose, they are also a very useful place to mount winches, lights and antennae.

 

There are three types of bullbars:

 

  • a nudge bar fits over the existing front bumper and covers part of the bumper.
  • an over bumper bar is the same thing but covers the entire bumper
  • a bull bar replaces the front bumper completely

 

The first two categories are usually purely cosmetic with little protection against collision.

 

The bull bar will give you better protection, and it comes in three types of construction:

 

  • Steel: stronger, cheaper and heavier
  • Alloy: lighter, more expensive and better looking (usually)
  • Plastic: the lightest of the three but not the toughest.

 


 

 

Rear Bars (Tow Bars)

 

EFS-rear-steel-bars


Rear bars will replace your vehicle rear bumper bar optionally with a wheel carrier or a carrier that mounts onto the chassis and preserves the existing rear bar.

 


 

Dual Battery Systems

 

Dual-Battery-System_piranha

 

As mentioned earlier, a dual battery system will come very handy with a fridge as it can provide a second battery in addition to the vehicle starting battery. The second battery can be mounted on specifically designed Single and Dual Battery Trays.

 

The primary vehicle battery is meant to start the engine and supply the vehicle electrical needs.

 

But it may not be adequate to run extra accessories such as fridges, electric winches, lights, radio equipment, therefore a second battery would help.

 


 

Roof Racks

 

roofrack_rhino


You can never have too much space in a vehicle, and after you fill the interior, the only way to go is to use the roof (unless you tow a trailer).

 

Roof Racks are handy places to store light and bulky items such as rooftop tents and camping chairs.

 

Not the best instead for heavy items like fuel or water but if there is no choice, then you will need to be aware of the change on the vehicle handling as well as increased fuel consumption.

 

Alloy roof racks are as strong as steel and far lighter, so they are highly recommended.

 


 

Driving Lights

 

narva_driving_lights

 

For urban driving, your headlights are more there so others can see you.

 

For offroad trips, it's all the way around, and you need extra light to light the way.

 

4wd driving lights usually come in two basic styles:

  • spotlights great for cruising and illuminating a long distance
  • wide-angle or spread-beam light is better suited for low-speed 4wd work.


And both can be either halogens or HID (High-intensity discharge). The latter is far superior by creating more light using less power. Halogens lights are usually cheaper.

 


 

Elockers 

 

ice_screenshot_20200629-161945


Elockers are locking differentials that massively improve the offroad capability for vehicles without modern traction control.

 

They can really simplify crossing challenging tracks and can be for front or rear.

 

The rear is usually the better choice since the rear axle is stronger, there are no CV joints to stress, and it's easier to steer with a rear locker than a front.

 


 

Rock Sliders

 

rock_sliders


Rock sliders other than helping you get in and out of the vehicle, protect your door sills as you slide over rocks.

 

The heavy-duty rock sliders are recommended because they can take the weight of the vehicle as it slides over rocks.

 

They can also work as good support for hi-lift jack in recovery situations.

 


 

Winches

 

Winching

 

A vehicle recovery with a winch is so much easier!

 

Usually, the maximum recovery load is around 1.5 times the fully-loaded vehicle weight, and they come in two types, electric winches and hand winches.

 

An 8000lb to 9500lb winch with a snatch block or two is usually enough for standard offroading.

 


 

Other 4wd accessories


The list is still big of all accessories and modifications you can fit in a 4WD if you go out touring.


canopies, heavy-duty clutches, heavy-duty seat covers, awnings and annexes, flares & grilles, cruise control kits, performance exhausts, and many more

Upper control arms

Read entire post: Upper control arms

 

The ultimate guide (2020 Update)

 

tough_dog_upper_control_arms

 

 

 

In this article where we are going to cover a few important points about upper control arms (UCA)

 

We are going to try and answer some of the most common questions you may have

 

Please bear in mind this is a general overview as suspension systems vary greatly between different model vehicles

 

 

What are suspension control arms and what do they do?

 

Upper and lower control arms are critical components on IFS vehicles that dictate the alignment of the road wheel as it moves up and down with suspension travel

 

They firmly hold the steering knuckles, axle spindles and road wheel to the vehicle while allowing the suspension to flex and maintain accurate steering geometry

 

It’s all thanks to the ball joints and rubber control arm bushings that allow this movement

 

Many controls arms (either upper or lower) have a limited range of adjustment, mainly to allow for setting camber and/or caster during wheel alignment

 

Camber is the angle of the tire with respect to the vertical axis of the car

 

Positive camber is when the top of the tire is leaning outward and the bottom of the tire is inward

 

 

Tyre-Alignment-Camber

 

 

Caster is the angle of the tire with respect to its steering axis (where it pivots when turning the steering wheel) against vertical

 

 

It is considered positive if pointing toward the front of the vehicle and negative if pointing toward the rear

 

blog

 

 

Why upgrade upper control arms?

 

 

If you have a suspension lift kit, please understand that you have just changed your 4WD suspension and steering geometry.

 


Your good-looking lift kit, other than allowing you larger tyres and more ground clearance, it has also lifted your chassis and body up and away from the mounting point of your wheels and tyres

 


Solid axle vehicles have a similar problem with the front diff rolling, but is easily corrected with some off-set bushes in the trailing arms

 

 

With IFS vehicles you need to be careful fitting a suspension lift as the original caster and camber specifications are pushed outside the acceptable limit

 


A lack of enough adjustment combined with typically short control arms causes your vehicle to lose camber/caster

 


This can cause your steering to become vague (tracking) with an out of control feeling

 


These issues can also greatly accelerate tyre wear costing you more money in the short term


 
To make things worse, fitting larger tyres can hit suspension components and even make contact with the chassis which is a problem that nobody needs

 

 

From the factory, most IFS 4WD's only come with a small amount of adjustment however, this is reduced when you add a suspension lift to your vehicle

 

 


This means when you do a wheel alignment, there will not be any adjustment available to set your vehicle’s camber or caster correctly

 


And please know that your vehicle’s instruction manual wheel alignment specs page does not take into consideration raised suspension or tyre size

 

Another serious issue found when lifting a vehicle with IFS is running out of movement in the ball joints

 


This is called ball joint binding and is caused by changing the suspension geometry to a point where the ball joint simply cannot move to a larger angle

 


The ball joint itself comes into contact with its own housing effectively reaching its maximum angle

 


While the ball joints may look okay parked on flat ground, when under conditions involving significant articulation (lots of suspension travel/extreme offroad) this can cause the ball joint to separate (pop out of socket) with the road wheel and steering knuckle coming loose from the control arm

 


Far from ideal!

 

 

So, what to do?

 


 
Simple:

 

 


Install modified upper control arms to your IFS 4WD


 

 

Luckily here in Australia, we have a choice of quality aftermarket upper control arms from well-known brands that can resolve all these issues

 


They have been redesigned to provide a better geometry for lifted vehicles, allowing the use of the standard adjustment for setting wheel alignment

 


They will effectively help to get the maximum performance and lifespan from your suspension, steering components and tyres

 


The positioning of the ball joint allows it to sit in a more neutral position providing full range of travel as per OE specs, effectively eliminating the binding issue

 

 

 


Tough Dog and Blackhawk by Roadsafe are among those


 

 

Here is a brief introduction of both:

 

 

Tough Dog upper control arms

 

 

UpperControlArm

 

Tough Dog upper controls arms features are:

  • Fixed position arm with increased caster (built in)
  • 1020 grade forged ball joint housing and end-rings (bush end)
  • Heavy duty, greaseable ball joints of OE size for easy replacement
  • Grease-free synthetic elastomer bushings
  • Free-pivoting bushings remove the chance of binding
  • increased clearance to strut/coil spring at full droop
  • increase strength exceeding OE versions

 

 

 

 

 

Blackhawk upper control arms (by Roadsafe)

 

 

 

326823_uca3841h_3_1024x467_full

 

 

 

Roadsafe upper control arms:

  • Fixed arm with increased caster (built in)
  • OE style/size rubber bushings
  • OE style/size ball joints.
  • Increased strength over OE

 

 

A lot goes into the design and manufacturing of an upper control arm kit

 

Thousands of dollars are spent in computer modelling, prototypes and testing before going to the market

 

Here in Australia they need to meet or exceed OEM specifications with the appropriate paperwork and engineering reports to receive ADR compliance (Australian Design Rule)

 

Although designed and manufactured to be ADR compliant this can be somewhat confusing as there is no Australian Design Rule for specific products like upper control arms

 

Roadsafe have ensured their control arms mount to standard fitment positions, have not moved or changed any of the mounting points and used OE specifications for bushings at the chassis

 

More detailed information is available upon request

 

 

 

Not all upper control arms are created equal

 

 

Different users (and uses) - different needs

 

Some aftermarket control arms are fully adjustable in both camber and caster, others have spherical joints at both ends

 

Tough Dog and Blackhawk UCA’s use a fixed position ball joint with heavy duty, OE specifications for the ball joint itself

 

Both brands specifically chose a fixed ball joint for off-road applications as the ball joint receives a large amount of bump / shock loads

 

Over time this could knock an adjustable ball joint out of position

 

These brands provide standard features such: 

  • 3 or more degrees of fixed caster correction which is the perfect amount of correction required for lifts ranging from 30-70mm
  • A fixed amount of caster offers the ability to use the factory adjustment to fine-tune the caster required for the vehicle's lift
  • Camber adjustment to meet OE specs
  • Maintain OE specification ball joint & bushings – you can use genuine replacement parts or aftermarket OE in case you need to replace a ball joint or bushing (OE spec bushing for Blackhawk only)
  • Positions for factory mounting of brake lines
  • Increased strength compared to the OE design 
  • Heavy-duty long-life ball joints

FJ40 FJ45 BJ40 BJ42 HJ45 HJ47 may sound like digits of a Medicare Card or Tax File Number but not for the passionate four-wheel driver enthusiast. He/she knows that those are the models of one of the most iconic 4wd of all time: the Toyota Land Cruiser 40 Series.

 

In this article, we’re going to cover off a few simple 40 series Landcruiser maintenance tips you can complete at home with a basic set of skills and tools. 

 

But before jumping in, it's fair saying that 4wd owners' friendly rivalry between the different brands of 4wds is one of the joys of being a passionate owner of an off-road machine.

 

There are a few 4wds that unite owners together: the Willys Jeep, a G60 Patrol or a Land Rover Series 1 short wheelbase. Such vehicles that we tend to agree are “just cool”.

 

There’s another 4wd that this article is going to cover off that arguably has no haters and that is the Mighty 40 series Landcruiser Troopy.

 

The 40 series Landcruiser Shorty has explored every corner of Australia numerous times and made itself famous for its exploits crossing remote deserts, floating across the Jardine River, to competing in the Tuff Truck Challenge.

 

Like all things man-made it has a couple of areas that need to be kept an eye on so let's explore how you can do them at home.

 

 

Let's dive in:

 

 

Check #1: Steering system

  • The 40 series Landcruiser power steering system has the bell crank Steering Idler Box out front on the chassis rail which is well known to wear and will cause sloppy steering response. It’s worth checking all Tie Rod Ends and Steering Box along with the steering system for play in any of the components. These are usually easy to adjust or change out although you may need to get a wheel alignment after this work.

 

 

 

Check #2: Wheel bearings

  • Jack up the front wheels and use safety stands, then hold the tyre top and bottom, push and pull the tyre to feel for play in the wheel bearings. Rotate the wheel feeling and listening for ‘rumbling’ that will indicate failing bearings. A slight rubbing sound could be the brakes and would be seen as normal. The rear bearings are a little harder to feel because the axle is connected to the wheel hub on full floating rear diffs from 09/1975 on. In an ideal world, you should remove the axle to check the rear bearings.

 

 

 

Check #3: Oil leaking

  • Look for oil leaking onto the inside of the tyre, this would be from the wiper seals on the front steering knuckle. This would often require a swivel hub rebuild as it is you will need to replace the inner axle seal fitted to rectify.

 

 

 

Check #4: Inlet manifold

  • On the petrol 2F motor, the inlet manifold is known to warp which will cause vacuum leaks that cause rough idle, a lean mixture and poor running

 

 

 

Check #5: Ignition components


 

 

Check #6: Ignition base timing

  • Check the ignition base timing and vacuum advance with a timing light.

 

 

 

Check #7: Diesel injection pump

  • The 2H Diesel injection pump on an HJ47 is vacuum operated and has a tendency for the leather diaphragm to fail to cause fast idle issues. This can be easily fixed by All Fourx4 but does need the expertise to change. If your oil pressure gauge reads high it indicates the common issue of a sticking oil relief valve. It’s easily fixed with an updated valve. 

 

 

 

Check #8: Air filter

  • Clean the air filter with compressed air by blowing from the inside out.

 

 

 

Check #9: Fluid levels

  • Check all fluid levels and condition by making sure the differential, gearbox and transfer case oils are not water contaminated. If the oil looks grey there’s water present and the component needs to be drained and flushed. You could consider fitting an extended diff breather system to stop water ingress in the future.

 

 

 

Check #10: Brake and clutch fluids

  • Consider flushing the brake and clutch fluid depending on when it was last done.

 

 

 

Check #11: Rubber hoses and belts

  • Inspect all rubber hoses and belts for cracks, leaks and signs of perishing, change as necessary.

 

 

 

Check #12: Fan Belt tension

  • Check Fan Belt tension. The correct tension is about 15mm of play in the longest run of the belt.

 

 

 

Check #13: Handbrake system

  • Check and adjust the handbrake system, this is normally located at the back of the Transfer Case.

 

 

 

Check #14: Inspect the radiator

  • Visually inspect the radiator for signs of coolant leaks around the core and tank joints.

 

 

 

Check #15: Spring shackle bushes

  • Using a pry bar, lever all spring shackle bushes inspecting for wear and play. 

 

 

 

Check #16: Inspect the springs

  • Inspect the springs for any broken leaves.

 

 

 

Check #17: U-bolt tension

  • Check U-bolt tension.

 

 

 

Check #18: Shock absorbers


 

 

 

Check #19: Grease nipples

  • Grease all grease nipples on the steering and drive shafts.

 

 

 

Check #20: Universal joints


 

 

 

Check #21: Differential drive flanges

  • By pushing up and down feel the differential drive flanges for play and signs of leaking from the pinion seal.

 

 

 

Check #22: Body mounts

  • Visually look at the body mounts to see if they are compressed or cracked, If they are they’re relatively easy to replace and will ensure the body stays connected to the chassis which is a good thing.

 

 

 

Check #23: Tyre pressures

  • Check all the tyre pressures and their condition. Look for deep cuts and irregular wear patterns. Consider doing a tyre rotation.

 

 

If you end-up needing new 40 series parts and start typing on Google things like "40 series Landcruiser Parts Australia" etc, you may not always find what you really need.

 

40 series Landcruiser body parts, Landcruiser 40 series chassis parts, or 40 series Landcruiser roof console, for example, are not always easy to come by, however, can be found in specialist 4wd shops such as the one you are reading right now.

 

All Four x 4 Spares stocks a wide range of 40 series Landcruiser parts for sale in this website and they provide a massive help whether you are doing a 40 series restoration or just a service.

 

If unsure give them a call on (02) 4041 4041 for any of the service items you may require such as 40 series power steering kit, 40 series air conditioning parts or if you need quality second hand 40 series doors, you may find them in their 40 series Landcruiser wreckers department.

 

Of course, if you find something during these checks and you would like their professional team of Landcruiser service mechanics to do the work for you on your 40 series ute, call their fully equipped Landcruiser repairs workshop in Kotara on (02) 4041 4003.

How to look after your 4WD's Automatic Transmission

Read entire post: How to look after your 4WD's Automatic Transmission

 

auto_conversion_orto1

 

 

Today we are going to talk about 4WD AUTOMATIC TRANSMISSIONS and how you can keep them in perfect shape without breaking the bank.


 

Automatic transmissions are a weird and wonderful design, as some would say foot goes down, magic happens, and power comes out. (If you like geeky stuff and want to learn more of how an Automatic Transmission works in engineering terms then watch this video)

 

How an Automatic Transmission works:

 

Auto transmissions are super easy to operate so that you can hold the wheel with one hand and eat a burger with the other, but, unfortunately, the driving force of our vehicles is not quite so simple and just the same as our engines, they require regular maintenance and pre-emptive modifications to aid the overall performance and longevity of our transmissions.

 

This, of course, starts with regular servicing of the oil and filtration system to give your transmission the best bet to keep performing at its best potential.

 

 

What is the biggest killer of an automatic transmission?

Good question, the simple answer is heating,

an overheating transmission is one of the leading causes of costly failures to our automatic transmissions.

 

OVERHEATING_TRANSMISSION

 

 

So, what causes this excessive heat?

Again, brilliant question! You’re good at this!

Number one measure of maintaining your transmission, and ensuring your internal oil temperatures are kept cool and manageable is a heavy-duty auxiliary transmission cooler

Mitsubishi-Triton-MQ-MN-Cooler-and-Bracket-800-x-800-1-400x400

 

yes, most vehicle manufacturers do have automatic transmission coolers fitted, however, these systems are tested under moderate conditions and not pushed to the true tough conditions our four-wheel drives are used for, be it fully loaded tough touring, towing the boat or caravan every weekend or hardcore four-wheel driving!

 

These are the areas where your standard transmission cooler will begin to build up excessive heat, causing hard-shifting and even worse, possible failure due to burnt/prematurely worn oil.

 

 

So how do I avoid this excessive heat, you ask?

I thought you’d never ask! Time for a home run.

 

As previously mentioned a heavy-duty front mount auxiliary transmission cooler is going to make an immediate difference to the performance and longevity of your transmission.

 


All Four x 4 Spares have a wide range of automatic transmission coolers specific to suit many makes and models, our coolers come with an especially Australian designed and manufactured mount which allows optimal airflow directly from the grille of your vehicle, ensuring the most efficient cooling possible!

Each kit has a top-quality, tried, tested and proven PWR cooler and 4mm thick E-coated mounting bracket, as well as high-quality hoses and fittings to suit, meaning you get the maximum confidence in your transmission cooling system. Give us a call on 02 4041 4041 to order one for your vehicle.


 

Although we touched on some key points above that will cause heat to rise to a damaging level in your transmission it is important to remember that on a hot day in even a lightly-loaded vehicle something as minor as a slight uphill rise can cause a major peak in transmission temperature leaving you stuck roadside, with a possibly failed transmission.

 

Much like having a winch fitted to your vehicle, an automatic transmission cooler is cheap insurance, not only making for a more comfortable drive from your transmission but potentially saving you thousands in costly repairs due to a failed transmission!

 

 

My Automatic Transmission is dead

 

If you are in a situation where your automatic transmission has completely failed, well then you won’t have any other options other than visiting an automatic transmission repairs workshop

 

Not wanting to blow our horns but our team of automatic transmission mechanics are specialists in transmission repairs, overhauls and auto transmission rebuilds. 

 

They’ll repair your automatic transmission with the highest level of speed and efficiency possible. If you are after some of the best automatic transmission mechanics in Newcastle and Hunter region only two hours drive from Sydney, then look no further and give them a call on 02 4041 4003

What about 4WD Manual Transmissions?

 

Does your 4WD have a manual transmission? All these automatic transmission talks may make you wonder what would be like off-road driving with an automatic transmission. 

 

Do you know that you can change your manual transmission to automatic? And let’s say you own a 70 Series Landcruiser and you want to make her quieter at highway speeds by dropping the rpm’s off your tacho and provide an overall improvement in comfort, performance and fuel economy.

If you’re one of those fortunate people who own a Toyota Landcruiser 80 series (any models such FJ80 FZJ80 HZJ80 HDJ80 etc), there is a slight possibility it needs a little bit of COVID-19 love from you. (If you’ll land here from the future: this post was written in May 2020 during the Coronavirus lockdown)

 

In this article, we’re going to cover off a few simple tasks you can complete at home with a basic set of skills and tools. 

 

Your 80 Series Land Cruiser service and maintenance will vary depending on how you have set it up and how you use it. The service requirements will vary slightly so with this in mind lets touch on some of the items you can look at for your vehicle.


 

Starting at the front end:

 

Task #1: Check the steering system

 

Check all bolts on the steering linkages and associated components. Check the steering system for play and adjust as required.


 

 

Task #2: Inspect the lower kingpin studs

 

The lower kingpin studs are known to come loose and should be checked with a torque wrench. (71Ft-Lbs/96NM) If they look as though they have been loose for some time it would be advisable to strip the knuckle down and investigate for any damage. Look for burrs and wear around the holes, studs and where the steering arm joins the knuckle. Check our Swivel Stud Kits in stock

Task #3: Inspect the steering box and upper panhard chassis mount

 

for fatigue cracks. These can be repaired with one of the many welds in repair kits available.


 

 

 

Task #4: Inspect the power steering hoses, pump and reservoir for leaks and weeps

 

The power steering reservoirs are renowned for weeping around the top crimp.

power_steer_lines_

 

Task #5: Inspect all tyre pressures

 

and look for feathering, scalloping, cuts and uneven wear patterns and tread wear indicators. 


 

 

 

Task #6: Inspect the wheel bearings

 

Jack up each wheel and by holding the top and bottom of the tyre feel for any play in the wheel bearings. Rotate the wheels feeling and listening for abnormalities like rumbling or scraping sounds. Be aware that the brake pads may make a slight rubbing noise which is ok. The rear bearings are a little harder to feel because the axle is connected to the wheel hub. In an ideal world, you should remove the axle to check the rear bearings. Our range of: Wheel Bearing Hub Kits


 

 

Task #7: More checks around the wheels

 

While you are at each wheel look for oil leaks around the knuckles and hubs. I also inspect the shock absorber and sway bar bushes at this time.

 

swaybar_front

 

 

 

Task #8: Check the rear control arm bushes

 

Using a pry bar check all the front and rear control arm bushes for cracks and failures.

 

control_arm_bushes

 

 

Task #9: Check the rear axle drive hub studs and nuts

 

for signs of flogging, fretting and oil leaks. Check our 80 Series Rear Axle Hub Studs

 

axle_studs

 

 

Task #10: Check for worn seals

 

If you decide to repack the wheel bearings it’s worth considering the use of the Terrain Tamer Heavy Duty bearing kit. This comes with a cassette seal which resolves issues with worn seal surfaces.


 

 

 

Task #11: Check all fluid levels 

 

and condition making sure the differential, gearbox and transfer case oils are not water contaminated. If the oil looks grey there’s water present and the component needs to be drained and flushed.


 

 

 

Task #12: Check the air filter

 

for dust and blow it out from the inside with compressed air. Clean out the dust trap under the air filter box.

 

dust_trap_

 

 

Task #13: Check the condition and tension of all fan belts 

 

There should be no signs of cracks or fraying. The correct tension is about 15mm of play in the longest run of the belt.

Check our 80 Series Fan Belt Kits

drive_belt

 

 

Task #14: Check all hoses 

 

for leaks or damage and coolant hoses shouldn’t feel crunchy when you squeeze them.


 

 

 

Task #15: Grease the nipples..

(no, we don't mean to put grease on your partner’s nipples)

You’ll find 3 grease nipples on both front and rear driveshaft, grease these with a quality general purpose grease.


 

 

 

Task #16: Check the handbrake operation 

 

There should be 7 clicks when you pull on the hand brake lever and the car should hold on a slight slope.



 


All Four x 4 Spares has all the parts you require available in the Toyota Landcruiser 80 Series Parts section of our website.

 

If unsure give us a call on (02) 4041 4041 for any of the service items you may require such as Terrain Tamer Engine Filter Kits, Drive Belt kits, Swivel Kits, suspension bushes etc

Terrain Tamer Parabolic Leaf Springs

Read entire post: Terrain Tamer Parabolic Leaf Springs

What are parabolic leaf springs?

 

Terrain_Tamer_Parabolic_springs_suspensions_2

 

Terrain Tamer has recently introduced new parabolic leaf springs for the popular Toyota LandCruiser 70 Series and Toyota Hilux and we thought to put together different resources from Terrain Tamer itself as well as independent reviewers in order to describe what they are and how they work.

Allan_Gray_Terrain_Tamer

 

 

Allan Gray from Terrain Tamer wrote a great article about Parabolic Springs on the Automotive Technician Magazine.

 

 

 

Allan Gray's definition of parabolics is: a suspension system used many years ago when vehicles were produced using one, two or three tapered leaves instead of multipacks.

 

The idea was successful but appeared to go out of fashion when coil springs started being fitted to the form of family cars and light trucks. However, while parabolic tended to disappear from the light truck scene, they continued to be chosen for heavy-duty track applications.

 

Now Terrain Tamer has released a new design in parabolic leaf springs, bringing the technology back to the Toyota Landcruiser 70 Series.

 

The new springs are thicker in the centre and taper towards the ends in a true parabolic form, and each leaf is designed to act as a spring in itself. The standard spring is supplied with three leaves - two main leaves that operate when unloaded and a lower leaf that contacts the upper leaves through a pressure pad when a full load is being carried. It's proof of what happens when modern technology is applied to a well-proven idea.

 

Parabolics are now fitted standard to many vehicles, both light and heavy-duty, for a smoother quieter ride, lower unsprung weight and greater flexibility. During Terrain Tamer testing, they placed cameras on the undercarriage area to check articulation, chassis clearance and brake and acceleration characteristics.

 

It soon became evident that owing to the increased flexibility of the parabolics, any excessive load on the driveline resulted in the differential housing deflecting with the springs, reducing the shock loading on the crown wheel and pinion.

 

This situation is particularly advantageous in four-wheel driving situations, where rapid forward and reverse gear selection is often used to extricate a vehicle from an embarrassing mud-hole incident. As with all Terrain Tamer products, these springs have been tested in the rugged situation of the Australian outback.

 

Greater flexibility, quieter operation, up to 500Kg capacity and improved driver comfort, it's a win-win situation and once you fit them, you will wonder how you ever did without them.
