1, caused by oil leakage or bending of the shock absorber itself. , just replace it directly.

2. If the damping bearing is aged or abnormally worn, it can be directly replaced or lubricated.

3. If the damping spring is deformed, it can be replaced directly.

4. It is also possible that the wheel bearing is abnormal and can be replaced directly.

Second, check the shock absorber fault first is to look at:

1, check whether the shock absorber leaks oil. When it doesn't rain or wash the car, look directly at the shock absorber shell or dust cover. You can tell at a glance. Very intuitive.

2. There is listening. When driving at low speed, when the wheels pass through the convex part of the road surface or have slight vibration, they will make an embarrassing sound. The abnormal sound of shock absorber is different from other chassis, which is very dull. If it is a front shock absorber, there is still an obvious shock on the steering wheel. Looking for an experienced driver can accurately determine which one is hanging.

3. There is also pressing the upper part of each wheel suspension part by hand, such as pressing the front and rear fenders. The faulty shock absorber was pressed hard. This is a symptom of oil leakage from the shock absorber in the later period. This can only be judged by experienced maintenance technicians.

The shock absorber is broken, so it can only be replaced, but it can't be repaired.
