Common hydraulic shock absorber damages include: shock absorber oil leakage, shock absorber top rubber aging and shedding, and shock absorber spring fatigue softening.
Oil leakage of shock absorber: When the vehicle is running, the damping effect will be greatly reduced until the hydraulic oil leaks out, and the car will have no damping. The unilateral damping oil leakage will make the body high and low, causing the fault of driving deviation.
Aging and falling off of the top rubber of the shock absorber: After the top rubber is aging and falling off, when the vehicle shakes up and down, the shock absorber will directly collide with other parts, make abnormal noises, and may further damage other parts.
Damping spring fatigue softening: the extension capacity of the spring decreases. When the car sinks, the damping spring cannot give the vehicle a greater reaction force. The sinking speed of the vehicle will be faster than normal, and the effect of damping and buffering will be If it drops, because the shock absorber spring cannot sufficiently slow down the body sinking, the hydraulic pressure received by the shock absorber will increase, which will quickly cause the shock absorber to leak oil.
