1. Abnormal noise: abnormal noise when driving, and the vehicle shock absorber will make abnormal noise when working.
2. Noise becomes louder: When the shock absorber is working, it will transmit the absorbed vibration and impact from the frame to the driver's cab without reservation.
3. Direction deviation: there may be slight deviation in the direction of the vehicle, which is difficult to correct, and the correction strength is low.
4. Abnormal sound of in-situ steering: excessive wear and damage of the top rubber will make a very obvious abnormal sound when the steering wheel is moved in situ.
