1. Trouble phenomenon: When the car is running, every time it vibrates up and down, the suspension device will make a "cuckling" noise, indicating that the suspension device is not working properly.
2. The cause of the failure
(1) The shock absorber is damaged;
(2) Damaged shock absorber rubber sleeve;
(3) The tightening bolts are loose.
Three, fault inspection and troubleshooting methods
A normal shock absorber will generate heat when it is working. If it does not generate heat or oil leaks from the shock absorber, it means that the shock absorber has been damaged. During the inspection, check the condition of the shock absorber rubber sleeve. If it is damaged, it should be replaced with the shock absorber in time.
