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.
