What Causes the Metallic Impact Sound When the Suspension Goes Over a Bump?
1 Answers
Suspension top mount. The car's suspension consists of springs and shock absorbers, which function to reduce the reactive force of the springs absorbing shocks and to absorb impacts from the road surface, thereby achieving vibration damping and noise reduction. If you hear a collision sound, it may indicate an issue with the shock absorber. Below is an introduction to suspension-related issues: 1. Definition of a shock absorber: The car shock absorber (including the suspension spring) is the most crucial component in the vehicle's vibration filtering system. 2. Function of the shock absorber: It absorbs vibrations and impacts caused by uneven road surfaces while driving, providing a comfortable ride for passengers. 3. Hazards of a damaged shock absorber: If the shock absorber is damaged, the vehicle may experience excessive bouncing and instability during driving, which can significantly impact driving safety in severe cases. 4. Common damages to shock absorbers: (1) Abnormal noise: If the shock absorber produces abnormal noises when driving on bumpy roads, it is likely due to damage. (2) Oil leakage: Inspect the shock absorber through the wheel arch using a flashlight. If oil leakage is observed on the exterior of the shock absorber, it indicates damage. (3) Loose chassis: When driving on bumpy roads, if the vehicle exhibits excessive bouncing and instability, it usually indicates a problem with the shock absorbers.
