Note: In order to quickly attenuate the vibration between the frame and the car body and improve the riding comfort and comfort of the car, the suspension system of the car is generally equipped with shock absorbers, and double-acting cylinder shock absorbers are widely used in cars.

After determining that there is a problem or fault with the shock absorber, first check whether the shock absorber leaks oil or has traces of old oil leakage.

The oil seal gasket and gasket are damaged, and the oil tank cover nut is loose. It may be that the oil seal and sealing washer are damaged and failed, so a new seal should be replaced. If the oil leakage still cannot be eliminated, pull out the shock absorber. If you feel that there is a hairpin or the weight is different, further check whether the gap between the piston and the cylinder is too large, whether the piston connecting rod of the shock absorber is bent, and whether the surfaces of the piston connecting rod and the cylinder are scratched or scraped.

If there is no oil leakage from the shock absorber, check the connecting pin, connecting rod, connecting hole and rubber bushing of the shock absorber for damage, desoldering, cracking or falling off.

If the above inspection is normal, the shock absorber should be further disassembled to check whether the fit clearance between the piston and the cylinder is too large, whether the cylinder is tight, whether the valve seal is good, whether the disc is tightly attached to the valve seat, and whether the extension spring of the shock absorber is too soft or broken. Repair by grinding or replacing parts as appropriate.

In addition, the shock absorber will produce noise in actual use, which is mainly caused by the collision between the shock absorber and leaf spring, frame or shaft, damage or loss of rubber pad, deformation of dust-proof pipe of shock absorber, oil shortage and other reasons. The cause should be found out and repaired.
