Maintenance of automobile shock absorbers
1. Press the bumper firmly and release it. If the car has 2~3 jumps, the shock absorber works well.
2. When the car is driving slowly and braking urgently, if the car vibration is severe, it indicates that the shock absorber has a problem.
3. Let the car stop after driving for 10km on the road with poor road conditions, and touch the shock absorber shell by hand. If it is not hot enough, there is no resistance inside the shock absorber, and the shock absorber does not work. Changzhou Jiale thinks that at this time, the appropriate lubricating oil can be added and then tested. If the outer casing is hot, the inside of the shock absorber is lacking in oil, and the oil should be added. Otherwise, the shock absorber is invalid.
4. Remove the shock absorber and erect it, and clamp the lower end connecting ring on the vise. Pull the damping rod several times. At this time, there should be stable resistance. The resistance to pull up should be greater than when pressing down. Resistance, such as unstable or no resistance, may be due to lack of oil inside the shock absorber or damage to the valve parts. Repair or replacement of parts should be performed.
