The failure or damage of the shock absorber will directly affect the driving stability and ride comfort of the car, as well as the service life of auto parts. Therefore, the inspection and maintenance of the shock absorber is essential. When the car is driving on uneven roads for 10-15 kilometers, touch the shock absorber shell with your hands. If it does not generate heat, it indicates that the shock absorber may have lost its shock absorption effect due to lack of oil or damage to the main parts. Replace with new parts.

If there is abnormal continuous vibration during the driving of the car, carefully check whether the shock absorber is leaking, and if it is leaking, it should be eliminated. When performing secondary maintenance on the car, check the working condition of the shock absorber. The inspection method is: fix the lower end of the shock absorber on a vise, stretch and compress it several times by hand, a normal shock absorber should have a certain damping force, and the resistance to stretching should be greater than the resistance during compression. If it is unstable or there is no resistance, it may be that the shock absorber is short of oil or the parts are damaged, and new parts should be repaired or replaced.
