The shock absorber is undoubtedly an important part of the car. When the vehicle encounters potholes during the driving process, the cushioning and damping of the shock absorber are completely needed to ensure the stability and safety of the car body. If the cushioning link is damaged, it will feel about driving. And the safety of the car body. Common types of shock absorbers are hydraulic shock absorbers, spring shock absorbers, rubber shock absorbers, air cushion shock absorbers, etc. Most of the shock absorbers on cars are hydraulic shock absorbers.
1. On a flat road, you can slightly hear the "cooing" sound from the front of the vehicle, which intensifies when turning sharp turns. When parking and checking, press the front of the vehicle hard to make it bounce up and down, abnormal noise appears, and the harder the harder, the louder the noise.
Diagnosis 1: The vehicle usually runs on bad roads and is not properly maintained, causing oil leakage and damage to the shock absorber.
Solution: In this case, repair or replace according to the severity of the damage.
2. Oil leakage, oil seeps from the oil seal on the upper part of the shock absorber, and once the shock absorber moves, the oil drips more severely.
Diagnosis 2: The sealing performance is lost due to damage to the oil seal caused by damage to the piston rod or foreign matter attached.
Solution: In this case, we recommend replacing new parts or new shock absorbers.
3. When starting or braking, the body bumps up and down violently, and the passengers feel unstable. .
Diagnosis 3: The shock absorber is old and aging.
Solution: We recommend replacing the shock absorber to make the body bump up and down, reduce small vibrations and make the ride more stable and comfortable.
The shock absorber is usually checked every 100,000 kilometers. The maintenance period between different models may be slightly different. When your car needs to be replaced and maintained, please find out through the "self maintenance" function.
Note: It is best to replace two shock absorbers at a time. When one of the front or rear shock absorbers is defective, you need to replace both the front shock absorber or the rear shock absorber with FAW, because when you replace one, the car The uneven force on the balance will cause different forces on the shock absorber, and even shock absorber problems will occur!
