Many car owners will hear a “thump, thump, thump” sound when passing speed bumps, and feel that the car's damping performance deteriorates. Although sometimes check the shock absorber did not find obvious problems, but how to accurately determine whether the shock absorber is damaged, and when the need to replace the shock absorber, is a common concern of car owners.
How to determine whether the shock absorber is damaged?
Steering Wheel Vibration: When small parts in the shock absorber, such as piston seals and valves, wear out, it can lead to unstable flow, which triggers steering wheel vibration. This vibration is more pronounced when driving over rough road surfaces.
Leaking shock absorbers: Leaking shock absorbers are a common sign of damage. Leaking oil will cause the shock absorber to lose performance, and if the leak is severe, the shock absorber will fail completely.
Rattles: Shock absorbers may produce rattles when damaged. However, during a general inspection, the 4S store may not perform a test drive if the rattling problem is not specifically noted.
How often do car shock absorbers need to be replaced?
Popping test: observe the popping by pressing on the front or rear corners of the car. If the bouncing is excessive, it may indicate that the shock absorber is damaged.
Kilometer check: It is recommended that the shock absorbers be checked regularly every 20,000 kilometers, replacement is considered at 80,000 kilometers, while at 100,000 kilometers it is recommended that they must be replaced.
Tire wear: Damaged shock absorbers may cause uneven wear or unusual grooves on the surface of the tires, which is a clear sign that the shock absorbers should be replaced.
Oil leakage: once the shock absorber is found to be leaking, it should be replaced in time.
Through the above methods, car owners can more effectively determine whether their car shock absorbers are damaged and whether they need to be replaced, so as to ensure the comfort and safety of driving.
