How does car suspension work?

Suspension components keep tyres in firm contact with the road to maximise grip, stability and braking.

How much does it cost to repair suspension?

Costs vary by diagnosis. An inspection will confirm whether bushes, shocks or other parts require replacement.

What are warning signs my suspension needs attention?

Clunks or squeaks over bumps, uneven tyre wear, instability when braking, or the vehicle pulling to one side.

Is driving with damaged suspension recommended?

No. It compromises control and braking. Arrange an inspection as soon as possible.

Common suspension problems we see

Misalignment, worn rubber bushes, tired or leaking shocks, incorrect parts installed and ride-height issues from unsuitable lift setups.

Typical time to complete a suspension repair

Around 1–5 hours depending on the vehicle and scope of work.

Symptoms of poor wheel alignment

Off-centre steering wheel, pulling, vibration and rapid or uneven tyre wear.

Consequences of skipping alignment

Reduced handling precision and faster tyre wear, which increases costs.

When to replace suspension bushes

Replace if cracked, perished or moving excessively. Polyurethane replacement bushes can improve durability.

When does a 4x4 lift kit make sense?

If you need more clearance, load capacity or space for larger tyres. Always select a vehicle-specific, road-legal setup.

Do I need regular alignment and suspension checks?

Yes. Alignment preserves geometry and tyres, and routine checks catch issues early.

How often should I align the wheels?

About annually, or sooner after rough-road use, impacts or suspension changes.

How often to check the power steering system?

Follow the service schedule; periodic inspections around every 20,000 km help prevent pump and rack issues.

Chassis components play a vital role in maintaining vehicle alignment, structural integrity, and overall driving performance in a 4WD. As vehicles age or are subjected to off-road use, towing, and added accessories, chassis-mounted components can wear or shift, affecting ride quality, handling, and vehicle control.

Why Upgrade 4WD Chassis Parts?

Off-road driving, suspension upgrades, and constant load can place increased stress on chassis-mounted bushings and brackets. Over time, worn or degraded components can lead to unwanted movement, misalignment, noise, and reduced driving confidence.

Upgrading chassis parts helps restore proper alignment, reduce unwanted movement, and support consistent handling. Maintaining these components is essential for ensuring your 4WD continues to perform as intended both on-road and off-road.

4WD Chassis Parts Range

The 4WD chassis parts range includes supporting components designed to maintain alignment, stability, and correct operation of key vehicle systems.

Body mount bush kits: Body mount bush kits are designed to isolate the vehicle body from the chassis while maintaining correct alignment. Replacing worn body mounts helps reduce vibration, improve body positioning, and restore structural stability.

Bonnet bush kits: Bonnet bush kits help maintain correct bonnet alignment and reduce movement or rattling. They support consistent panel fitment, particularly on vehicles exposed to rough terrain.

Chassis brace kits: Chassis brace kits are designed to improve structural rigidity and reduce chassis flex. They help maintain alignment and contribute to improved handling and vehicle stability, especially in off-road conditions.

Fan mounts: Fan mounts secure cooling system components in the correct position. Maintaining proper fan alignment is essential for reliable cooling performance and preventing component contact or damage.

Headlight sensor brackets: Headlight sensor brackets are designed to maintain correct headlight levelling operation after suspension or ride height changes. They help ensure headlights function as intended and remain correctly aimed.

Power window bushings: Power window bushings support smooth and reliable window operation. Replacing worn bushings helps restore proper function and reduces binding or uneven movement.

Sunroof bushings: Sunroof bushings help maintain correct sunroof alignment and operation. They support smooth opening and closing while reducing noise and wear over time.

Throttle bush kits: Throttle bush kits are designed to restore smooth throttle pedal operation. Replacing worn bushings can improve pedal feel and consistency in throttle response.

Together, these components help support correct chassis function and long-term vehicle reliability.
