1. Stop the car after driving 10km on the road with poor road conditions, and touch the shock absorber shell with your hand. If it is not hot enough, it means that there is no resistance inside the shock absorber and the shock absorber does not work. At this time, appropriate lubricating oil can be added, and then the test can be carried out. If the outer casing is hot, it means that the inside of the shock absorber is short of oil, and enough oil should be added; otherwise, the shock absorber is invalid.
2. When we are driving the vehicle normally, we perform the sudden braking action to observe whether the vibration of the car is severe. If the vibration is decoupled, it means that there is a problem with the shock absorption system of the car, and we need to improve it in time.
3. We can press the bumper of the car and release it to see if the car has a tendency to jump. If there is, it means that the shockproof function of the car is good.
