Reasons for Squeaking Noise When Pressing the Rear Shock Absorber of a Car
1 Answers
Car rear shock absorber squeaking is generally caused by abnormalities in the shock absorber or the shock spring. Below are the methods to address the squeaking noise and diagnose the fault: 1. Apply lubricating oil: For a squeaking rear shock absorber, you can apply some lubricating oil to the rear shock or replace the shock rubber sleeve. If there is a squeaking noise, it is mostly due to abnormal operation after oil or air leakage, and it is recommended to replace the shock absorber with a new one. The shock absorber is a wear-prone component during car use, and its performance directly affects the smoothness of the car's ride and the lifespan of other components. Therefore, the shock absorber should always be kept in good working condition. 2. Diagnosis method: After driving the car on a road with poor conditions for 10km, stop and touch the shock absorber housing with your hand. If it is not hot enough, it indicates there is no internal resistance in 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 filled. Otherwise, it indicates the shock absorber has failed. Press the bumper firmly and then release it. If the car bounces 2-3 times, it means the shock absorber is working well. When the car is driven slowly and then braked suddenly, if the car vibrates violently, it indicates a problem with the shock absorber.
