179. Shock absorber

A shock absorber is a suspension component that controls the movement of a vehicle's springs and wheels. It reduces excessive bouncing after bumps and helps keep the tyres in consistent contact with the road.

Worn or damaged shock absorbers can reduce vehicle stability, increase body movement and negatively affect steering and braking behaviour. They should be inspected if the vehicle bounces excessively, handles poorly or shows signs of fluid leakage.

What does a shock absorber do?

A shock absorber controls suspension movement by damping the repeated movement of the springs. This helps stabilise the vehicle and maintain tyre contact with the road.

What are signs of worn shock absorbers?

Possible signs include excessive bouncing, increased body movement, poor stability, unusual suspension noises, uneven tyre wear or visible fluid leakage from the shock absorber.

Are shock absorbers the same as springs?

No. Springs support the vehicle and allow the suspension to move over bumps, while shock absorbers control and damp that movement. The two components work together as part of the suspension system.
