What Causes the Squeaking Noise in a Car's Shock Absorbers?
1 Answers
Reasons for the squeaking noise in a car's shock absorbers: Shock absorber oil leakage: Oil leakage can lead to a decrease in the shock absorber's resistance. This may cause the valve assembly to hit the bottom of the barrel. Additionally, the reduction in oil can increase friction between the internal valve and the barrel, resulting in abnormal noises. Improper spring installation: The noise from the shock absorber may be due to improper spring installation. For shock absorbers with a tray, there should be a certain distance between the spring and the tray's limit during installation. This prevents the spring from hitting the limit during deformation, which could cause abnormal noises. Friction between the shock absorber's top rod and oil seal: Abnormal noises can also arise from friction between the shock absorber's top rod and oil seal. If the shock absorber is left unused for a long time, the lubricating grease at the oil seal may dry out, leading to dry friction between the oil seal and the top rod, which causes the noise.
