What Causes Abnormal Noises in Car Shock Absorbers?

[McMatthew]

Abnormal noises in car shock absorbers are caused by oil leakage or bending of the shock absorber, aging or abnormal wear of the shock pressure bearing, or deformation of the shock spring. The solution is to replace the shock absorber. The main function of a shock absorber is to ensure smooth vehicle operation, dampen vibrations, and provide a more comfortable ride for passengers. It primarily works by suppressing the spring to absorb oscillations and impacts from the road surface. Methods to check shock absorbers: In dry conditions or when the car hasn't been washed, directly inspect the shock absorber housing or dust cover for any signs of oil leakage. Press down on the upper part of the suspension near each wheel; a faulty shock absorber will feel excessively stiff. Principle of shock absorbers: Shock absorbers are used to suppress the oscillation of springs after absorbing shocks and to mitigate impacts from the road surface. They are widely used in automobiles to accelerate the attenuation of vibrations in the frame and body, thereby improving the vehicle's ride comfort. When driving on uneven roads, although the shock-absorbing springs can filter out road vibrations, the springs themselves still undergo reciprocating motion. The shock absorber is designed to suppress this spring bouncing.
