Normally it will work well between 48.000 and 64.000km, if exceeded the shock absorbers will become weaker.

The most common and easily noticeable sign of a car shock absorber problem is the phenomenon Car oil leaks. The structure of the shock absorber will have seals to prevent oil from escaping. However, after a period of use, hydraulic oil leaks and flows along the body surface of the shock absorber system. You need to replace the seal to fix this situation.

In case the car owner knows the exact parameters of the vehicle, suspension system, then the standard parameter can be compared with the vehicle's height to check. If there's a difference between the height and the benchmark, it's possible that a part of the suspension or the shock absorber spring has been damaged.

9 Check the springiness of the shock absorber

Checking the damping is also one of the methods to help car owners know if the car's shock absorber is damaged or not?

Or you can also use your knee to rest on the bumper hardware to test the bounce.'

10 Check the shock absorber tube & spring
