What are the symptoms of a faulty front shock absorber?

[DeDaniella]

The symptoms of a faulty front shock absorber include: 1. Abnormal noises from the shock absorber when driving on bumpy roads; 2. Oil leakage on the exterior of the shock absorber; 3. Excessive body bouncing and instability when driving over uneven surfaces; 4. High temperature on the shock absorber casing after driving. The working principle of a shock absorber: When relative motion occurs between the frame or body and the axle due to vibration, the piston inside the shock absorber moves up and down. The oil inside the shock absorber chamber repeatedly flows 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 a damping force that converts the vehicle's vibrational energy into heat energy of the oil, which is then absorbed and dissipated into the air by the shock absorber.
