4s store can repair.
Automobile shock absorber damage, need to repair the damper external oil leakage traces. If only due to oil leakage caused by failure, you can replace the oil seal, add enough lubricant, generally do not need special maintenance; such as due to damage failure, should replace the assembly, shock absorbers are divided into two kinds, one is hydraulic shock absorber, the other is air shock absorber. Hydraulic shock absorber is the hydraulic oil in the shock absorber, when the car is traveling on an uneven road and jitter, hydraulic oil has an incompressible nature, will give the vehicle to the downward sinking of a reaction force, the shock absorber has a relatively small pressure relief valve, you can let the hydraulic oil slowly out, that is, to slow down the vehicle sinking speed. Hydraulic shock absorber system also has a shock absorbing spring, shock absorber and shock absorbing spring work at the same time, can give the car to play the role of buffer shock absorption, reduce the fatigue of the driver and passenger bumps.
Hydraulic shock absorber damage is common: shock absorber oil leakage, shock absorber top rubber aging, fall off, shock absorber spring fatigue softening. Shock absorber leakage in the oil: vehicle driving, the damping effect will be greatly reduced until the hydraulic oil leakage, the car will have no damping, unilateral shock absorber leakage will make the body side of the high side of the low, resulting in the failure of the driving bias. Shock absorber top rubber aging, fall off: top rubber aging off, when the vehicle up and down shaking, the shock absorber will directly touch with other parts, issued by the noise, and may further damage other parts. Shock absorber spring fatigue softening: the spring's tensile capacity decreases, when the car sinks, the shock absorber spring can not give the vehicle a greater reaction force vehicle sinking speed will be faster than normal, shock absorption, buffer effect will be reduced, due to the shock absorber spring can not be adequately slowed down the body sinking, shock absorbers will be subjected to the increase in hydraulic pressure, which will lead to the rapid leakage of shock absorber oil.
