If the failure is only caused by oil leakage, the oil seal can be replaced, and sufficient lubricating oil can be added. Generally, no special maintenance is required. If it fails due to damage, the assembly should be replaced.
Regarding whether it is necessary to replace the oil leakage of the shock absorber of the car in time, the key is to see whether the degree of oil leakage is serious. If it's only slightly oily, we don't have to replace it. However, if the oil leakage of the shock absorber is serious, we have to replace it in time.
However, whether it is a slight oil leakage or a serious oil leakage, as long as the leakage of the oil inside the shock absorber is reduced, it will have a certain impact on the damping force of the shock absorber. The main performance reflected in the cab is that the vehicle suspension becomes soft, even loose, abnormal noise and other problems. In severe cases, the shock absorber is very likely to be damaged due to bottoming on a large pothole road.
