If oil leakage from the shock absorber is found, first tighten the cylinder head nut. If the shock absorber still leaks oil, it may be that the oil seal and the sealing gasket are damaged and failed, and the new seal should be replaced. If the oil leak still cannot be eliminated, pull out the shock absorber rod. If you feel a hairpin or different weights, 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 there are scratches or pull marks on the surface of the piston connecting rod and the cylinder.
If the oil leakage occurs in the shock absorber of the car, it is undoubtedly a very dangerous thing for the shock absorber. Then, once the oil leak is found, it is necessary to make timely remedial measures. The key inspection items are the oil seal washer, the seal washer is broken and damaged, the oil storage cylinder cover, and check whether the nuts are loose in these parts.
