Leaking Shock Absorber
An oily, wet shock absorber body means its seal has failed and the damping oil is escaping. The car may bounce more and brake and corner less securely.
High risk
Have it checked soon. Worn shock absorbers lengthen braking distances and reduce grip.
Short answer · How do I know my shock absorber is leaking?
Look at the shock absorber body behind each wheel. A thin film of oil can be normal, but a wet, dirty body with drips means oil loss. The car may bounce after bumps, nose-dive under braking or feel floaty. Shock absorbers are usually replaced in pairs on the same axle.
Safe checks you can do
- Look at each shock absorberA wet, oily body with dirt stuck to it means a leak.
- Bounce each cornerPush down firmly and release: more than one bounce suggests weak damping.
- Check tyre wearCupped tread can come from worn dampers.
