How to Solve the Abnormal Noise from Shock Absorbers?
2 Answers
Here are the solutions for abnormal noise from shock absorbers: It is recommended to replace the shock absorber. Below is relevant information about shock absorbers: 1. Working Principle: When relative motion occurs between the frame (or body) and axle due to vibration, the piston inside the shock absorber moves up and down, causing the oil in the shock absorber chamber to repeatedly flow from one chamber to another through different pores. At this time, the friction between the pore walls and the oil, as well as the internal friction between oil molecules, creates a damping force that converts the vehicle's vibration energy into heat energy of the oil, which is then absorbed by the shock absorber and dissipated into the atmosphere. 2. Purpose: To accelerate the attenuation of frame and body vibrations and improve the vehicle's ride smoothness (comfort), most automotive suspension systems are equipped with shock absorbers.
I've been driving for over a decade and frequently encounter shock absorber noise issues. The most common causes are aging/cracked buffer rubber or oil seal leaks that create annoying knocking sounds while driving, which also affect vehicle stability and handling. First do a simple self-check: Park on level ground and use a flashlight to inspect the shock absorber area for oil stains or loose components, especially the top bolts and rubber bushings. For minor noises, try applying anti-rust lubricant as a temporary solution (but don't expect permanent results). Safety is my top priority - persistent noises require professional diagnosis at a repair shop where technicians can accurately determine whether to replace small components or the entire shock assembly using specialized equipment. During routine maintenance, make shock absorber inspection a habit (I check every three months during car washes) - this practice saves money and ensures peace of mind. Don't delay until problems worsen; last year my neglect resulted in a four-figure repair bill. Safe driving should always come first.
