How to Determine if the Shock Absorber Spring is Damaged?
1 Answers
Methods to determine if the shock absorber spring is damaged are as follows: 1. Drive the car on a road with poor conditions for 10km, then stop and touch the shock absorber housing with your hand. If it is not hot enough, it indicates there is no resistance inside the shock absorber, meaning it is not working. At this point, you can add an appropriate amount of lubricating oil and test again. If the housing becomes hot, it means there is insufficient oil inside the shock absorber, and it should be refilled. Otherwise, it indicates the shock absorber has failed. 2. Press down hard on the bumper and then release it. If the car jumps 2~3 times, it means the shock absorber is working well. 3. Drive the car slowly and apply emergency braking. If the car vibrates violently, it indicates a problem with the shock absorber. 4. Remove the shock absorber, stand it upright, and clamp the lower connecting ring in a bench vise. Pull and press the shock absorber rod several times with force. There should be stable resistance at this time, and the resistance when pulling up should be greater than when pressing down. If the resistance is unstable or even absent, it may be due to insufficient oil inside the shock absorber or damaged valve components, and it should be sent for repair or replacement of parts.
