What are the symptoms of a faulty front shock absorber?
1 Answers
When the front shock absorber is faulty, the following symptoms may occur: 1. Abnormal noises: If the shock absorber makes unusual noises when the vehicle is driving on bumpy roads, it is highly likely that the shock absorber is damaged. 2. Oil leakage: By using a flashlight to inspect the shock absorber through the wheel arch, if oil leakage is observed on the exterior of the shock absorber, it indicates that the shock absorber is already damaged. 3. Loose chassis: When driving on bumpy roads, if the vehicle exhibits excessive bouncing or unstable body movement, it is usually a sign that the shock absorber has a problem. Extension: Most vehicles currently use hydraulic shock absorbers, which operate on a relatively simple principle. The upper mount of the shock absorber is integrated with the piston and piston rod, connecting to the vehicle body; the lower mount is integrated with the pressure tube, connecting to the lower control arm of the vehicle frame. When the vehicle experiences relative movement due to vibrations, the piston inside the shock absorber moves up and down, forcing the hydraulic oil in the oil chamber to flow repeatedly from one chamber to another through the piston flow valve. The friction between the flow valve orifice wall and the oil, as well as the internal friction between oil molecules, creates a damping force that converts the vibration energy into heat and dissipates it into the atmosphere.
