How Long Do Shock Absorbers Last?

[DiGrant]

Shock absorbers typically have a service life of around 100,000 kilometers. Shock absorbers are used to dampen the oscillations from spring rebound after absorbing shocks and to mitigate impacts from the road surface. They are widely used in automobiles to accelerate the attenuation of vibrations in the vehicle frame and body, thereby improving ride comfort. The steps for replacing shock absorbers are: 1. Remove the shock absorber along with the coil spring, then use a spring clamp to secure the spring; 2. After replacing the shock absorber, release the spring clamp and reinstall the assembly. The working principle of shock absorbers is: when relative motion occurs between the vehicle frame 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 various orifices. The friction between the orifice walls and the oil, as well as the internal friction among oil molecules, creates resistance to vibration, converting the vehicle's vibration energy into thermal energy of the oil, which is then absorbed by the shock absorber and dissipated into the atmosphere.
