PERTHS 4WD SPECIALISTS

FOR ALL THINGS MECHANICAL AND ELECTRICAL

The performance of your four-wheel drive and its ability to handle off-road conditions and carry loads are heavily influenced by its suspension system. A well-functioning suspension system ensures the safe and comfortable operation of your vehicle, determines its load-carrying capacity, and affects the durability of its mechanical parts. On the other hand, an insufficient suspension system can compromise these factors.

If you plan to load your vehicle or venture off-road, it is highly likely that you will require an aftermarket suspension upgrade. This will ensure that your vehicle is prepared for any terrain or additional weight you encounter. To determine whether your 4WD needs a suspension upgrade, consider the following factors:

BELOW AVERAGE PERFORMANCE

When you're on the road or off-roading, the primary aspect to consider is the way your vehicle handles. Pay attention to signs such as excessive body roll during cornering, nose-diving when braking, or a bumpy ride when carrying a load. These indicators strongly suggest that your current suspension system may not be functioning optimally. Additionally, if your vehicle bottoms out even on minor ruts, it indicates that it is hitting bump stops when encountering uneven surfaces, which is not ideal for navigating difficult terrains with your vehicle.

SAGGING IN THE REAR

If your vehicle's rear sags when towing or carrying a heavy load, it indicates an overstressed suspension. This sagging accelerates the deterioration of mechanical components and makes driving more challenging with reduced stability. This unmistakable indication implies that your rig needs an airbag suspension kit or another form of suspension upgrade to enable secure towing and handling of heavier loads.

SUSPENSION OVERLOAD

If you have made any additions to your vehicle, such as accessories, it is crucial to have your suspension system inspected. When it comes to your suspension, it is important to ensure proper fitting, taking into account the installed accessories and the typical weight of the loads you usually carry. In fact, an upgrade may be necessary, particularly if you have long-range fuel tanks, bull bars, or winches installed.

NOSE DIVES WHEN PRESSING THE BRAKES

That's correct! Worn-out shocks or struts can lead to a phenomenon known as "nose diving" when you apply the brakes firmly. When you brake, the weight of the vehicle shifts forward, and the front suspension should compress to maintain stability and control. However, if the shocks are worn out, they won't be able to effectively dampen this movement, causing the front end of the vehicle to dive downward excessively.

This diving motion can negatively impact your ability to stop the car quickly in emergency situations. With worn-out shocks, the weight transfer to the front end of the vehicle can cause a decrease in tire traction and braking efficiency, increasing the distance required to come to a stop. This can be particularly dangerous when you need to stop suddenly to avoid a collision.

EXCESSIVE TYRE WEAR

Uneven wear or bald spots on your tires can indeed be an indication of suspension issues. When the suspension system of a car is not functioning properly, it can lead to uneven weight distribution on the tires, resulting in uneven wear patterns.

There are several suspension-related problems that can cause uneven tire wear:

Misalignment: Improper wheel alignment can cause the tires to wear unevenly. If the wheels are not properly aligned, it can lead to excessive wear on certain areas of the tire. Worn suspension components:
Worn-out suspension components such as ball joints, control arms, or bushings can affect the alignment and stability of the wheels. This can result in uneven tire wear.
Shock absorber or strut issues: Faulty or worn-out shock absorbers or struts can fail to provide proper support and damping to the vehicle's suspension. This can lead to excessive bouncing or uneven weight distribution, causing uneven tire wear.
Improper tire inflation: Incorrect tire pressure can also contribute to uneven wear. Overinflated or underinflated tires can cause the tread to wear unevenly, particularly in specific areas.

VISUALLY INSPECT THE STRUT MOUNTS

Taking this step is relatively effortless and doesn't necessitate raising the car using a jack. Begin by accessing the interior of your vehicle's engine compartment by unlatching the hood. Once opened, direct your attention towards the strut or shock towers situated on either side, typically extending through the fender just above each wheel, firmly secured by an assortment of bolts and nuts.

As you inspect the fasteners, make sure to remain observant of any indications of corrosion or rust that may be present. Pay particular attention to the fasteners that overlap and are not exhibiting signs of being loose or suffering from any other type of damage.

MEASURE THE HEIGHT OF YOUR FRONT WHEELS

Using a tape measure, carefully measure the distance of the empty space stretching from the top of the tire to the bottom of the fender on the driver's side of the vehicle. Ensure precise measurement accuracy by taking your time and being meticulous in your approach.

After completing this measurement, proceed to repeat the same procedure on both sides of the vehicle, specifically the passenger sides. It is essential to compare and evaluate any potential disparities in height between the two sides.

In the event that you observe a slight variation in height, typically 2.5cm or less, there is no cause for significant concern as such minor deviations are generally acceptable. It is expected that the two sides should exhibit relatively similar measurements within this range.

However, if you happen to notice that one side is noticeably lower than the other, it is highly probable that the source of the issue can be traced back to that particular side. This discrepancy in height serves as a key indicator of a potential problem area.

Conversely, if both sides demonstrate a relatively even measurement and appear to be similar in height, it is still plausible that there may exist an underlying issue with the suspension that affects both sides. Consequently, it is crucial to proceed to the subsequent step outlined below to further investigate and address any potential suspension-related concerns.

IT’S TIME TO JACK UP THE CAR

Prior to getting underneath your car for a thorough examination, it is imperative that you retrieve the reliable jack that is essential for the task at hand. Take care to consult the owner's manual, as it contains valuable information regarding the specifically designated jack points. Undertaking the task of lifting the car without adhering to the prescribed jack points may result in considerable harm to the vehicle, while simultaneously exposing you to potential risks and hazards.

LOOK FOR SIGNS OF DAMAGE OR GREASE

If you're having difficulty observing the underside of the car, using a flashlight would be advisable. Take a close look at the rubber bushings on each wheel individually. These components play a crucial role in isolating the metal sections of the suspension. Typically, they are black in color, but over time they may become gray due to wear and tear.

Pay attention to any cracks or tears in the bushings, as these indicate the need for replacement. When a rubber bushing is worn out, it fails to effectively separate the metals, resulting in a rougher and noisier ride.

If a bushing is absent or torn, we strongly advise against driving your car any further, as it compromises the vehicle's ability to handle shocks when encountering bumps, putting both you and other drivers at significant risk on the road.

CHECK THE TIE ROD ENDS

We will provide you with step-by-step guidance for this slightly more intricate step. Begin by identifying the power steering box, then trace the arms leading towards the wheels. If you encounter difficulties locating it, consulting the owner's manual may be necessary, as its position can vary depending on the make and model of the vehicle.

The tie rod plays a crucial role in the suspension system, acting as a link between the steering box and the wheels. If the bushings become worn out or damaged, it can lead to diminished handling and the presence of dead spots during steering. This poses a significant hazard as it can impede your ability to control the vehicle effectively, making driving highly unsafe.
