Should Shock Absorbers Be Replaced Individually or in Pairs?

[DeCassandra]

It is recommended to replace them in pairs. Replacing just one can lead to uneven height on both sides, and the other side is also prone to damage. The function of shock absorbers is to maximize the buffering of the vehicle's center of gravity height movement and save energy, thereby reducing wind resistance and mitigating the impact of changes in the vehicle's center of gravity on the tires. Below are specific methods to check if the shock absorbers are functioning properly: 1. Oil leakage: If oil leakage is detected, it indicates a malfunction in the shock absorber, which should be replaced or repaired as needed to prevent abnormal operation. 2. Press the bumper: Press the bumper firmly and release it. If the vehicle bounces 2-3 times, it indicates that the shock absorber is working well. 3. Observe vehicle vibration: When driving slowly and applying emergency brakes, if the vehicle vibrates violently, it suggests a fault in the shock absorber. 4. Casing temperature: After driving 10km on rough road conditions, stop and touch the casing. If it is not hot enough, it indicates no internal resistance in the shock absorber, meaning it is not working.
