The noise generated by shock absorbers in actual use may be caused by oil leakage or bending of the shock absorber, aging or abnormal wear of the shock absorber pressure bearing, deformation or fracture of the shock absorber spring, damage to the balance bar rubber sleeve, or injury to the valve body inside the shock absorber or bending of the top rod. In addition, the nonlinear characteristics of the external characteristics of the shock absorber may also lead to noise.
1. Shock absorber oil leakage or bending
Oil leakage from shock absorbers can lead to ineffective lubrication inside the shock absorber, resulting in significant friction noise during operation. Bending of shock absorbers can also cause abnormal noises.
2. Shock absorber pressure bearing aging or abnormal wear
Aging or abnormal wear of pressure bearings can also cause abnormal noise.
3. The shock absorber spring is deformed or broken
The deformation or fracture of the shock absorber spring can make the car unable to filter out bumps, resulting in a sound when driving on bumpy roads.
4. The rubber sleeve of the balance bar is damaged or there is a gap in the connecting ball head
Damage to the rubber sleeve of the balance bar or gaps in the connecting ball joint can also cause abnormal noise from the shock absorber.
5. The valve body inside the shock absorber is damaged or the top rod is bent
Injury to the valve body inside the shock absorber or bending of the top rod can also cause abnormal noise in the shock absorber.
To solve the noise problem of shock absorbers, the following operations can be carried out according to the specific situation: replace the shock absorber with a new one, tighten the fixing nut, replace the rubber lining, replace the shock absorber spring, replace the wheel bearings, or repair the internal valve parts of the shock absorber. At the same time, in order to prevent the occurrence of shock absorber noise, it is recommended to develop good driving habits and avoid damage to shock absorbers caused by excessive bumps on the road.
