What Causes Shock Absorber Oil Leakage in Cars?

[DiAlex]

Shock absorber oil leakage is directly related to road conditions. The main causes of shock absorber oil leakage include the following aspects: 1. Poor internal cleanliness of 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 debris like mud and sand to enter the oil seal, leading to wear and oil leakage; 3. Aging of the sealing lip of the shock absorber oil seal, resulting in loss of sealing function; 4. Some car owners fail to properly cover the shock absorber when applying undercoating, causing the coating to adhere to the shock absorber piston rod and wear the oil seal, leading to leakage; 5. The support rod that controls piston movement needs to extend from one end of the metal tube, and this area requires strict sealing. Generally, oil leakage is directly related to improper sealing here. Hydraulic shock absorber oil leakage indicates that its service life is not long.
