What are the causes of car shock absorber oil leakage?
1 Answers
Shock absorber oil leakage causes: 1. Poor cleanliness inside the shock absorber, with welding slag, iron filings, and other debris causing oil seal wear. 2. Harsh working conditions of the shock absorber, allowing external mud, sand, and other debris to enter the oil seal. 3. Aging of the sealing interface of the shock absorber oil seal, losing its sealing function. 4. When spraying the chassis armor, the shock absorber was not properly covered, causing the armor to adhere to the shock absorber piston rod. 5. The extension rod that controls the piston movement needs to be extended at one end of the metal tube, and the poor sealing of this part leads to leakage. Solutions for car shock absorber oil leakage: 1. Oil traces on the surface of the shock absorber cylinder do not necessarily mean oil leakage. To determine whether the shock absorber is leaking or failing, it is necessary to judge whether replacement is needed based on factors such as the type of shock absorber, the level of leakage, and the location of oil traces. For shock absorbers with only slight leakage, replacement may not be necessary. Additionally, shock absorbers may exhibit oil seepage during normal operation, which is a normal phenomenon. 2. For pillar-type shock absorbers like front shock absorbers, if the oil film is between the oil seal cover and the spring seat, replacement is not needed. However, if oil leaks below the spring seat or seeps below the spring bracket or if droplet-like oil appears, the shock absorber needs to be replaced.
