Shock absorber damage analysis
The main function of the shock absorber is to alleviate the impact caused by the road surface, quickly absorb the vibration generated during the bump, and restore the vehicle to the normal driving state.
However, once the damper is damaged, it should be analyzed in detail.
1. If it is a functional failure, the inability to absorb shock will increase the number of vibrations of the vehicle.
2. Oil leakage or air leakage will cause an abnormal noise when the vehicle passes through the pit, and the vehicle is not buffered.
Simple judgment method:
1. Press the trunk down by hand and then release it. The vehicle stops in 3 vibration cycles as normal, otherwise it is recommended to check.
2. Lift the vehicle and check the appearance of the damper. If there is obvious oil stain (usually more than 1/2 of the total length), it is recommended to consult the maintenance personnel for replacement.
Note: It is necessary to distinguish between oil and water stains. If there is no problem with the shock absorber, it is not recommended to replace it. The original shock absorbers have been adjusted and matched. Different factories or different states have slight stability and control performance. influences.
