1. When driving through large potholes or raised road sections, the vehicle will make the sound of metal collision and vibrate more than once
2. The grip of the rear wheel slips, and it is prone to tail drift or understeer. Because the shock absorber also prevents the tire from bouncing off the ground, if it is damaged, it will affect the stability of the rear wheel
3. Passengers are prone to motion sickness. When the shock absorber is ineffective, the body will vibrate abnormally. People are prone to discomfort in a bumpy state, resulting in motion sickness
4. The handling becomes poor. Especially when driving at high speed, the steering of the vehicle is not sensitive under the condition of shaking, and the daily effect cannot be achieved when braking, and the driver's ability to control the vehicle is reduced.
