The shock absorber will make a noise in actual use. This is mainly caused by the collision of the shock absorber with the leaf spring, the frame or the bearing, the damage or fall of the rubber pad, the deformation of the shock absorber dust tube, and the lack of oil. This situation is relatively common.
In addition, abnormal noise may occur after the shock absorber of the car is damaged. The specific performance is that when passing through a bumpy road section, the shock absorber makes an abnormal noise. The tires wear unevenly, and the vehicle will experience uneven vibration during driving, and the wheels will tilt, which will increase the discomfort of bumps.
