Even if there is only one shock absorber for oil leakage or other problems, Fuye here recommends replacing all four shock absorbers or at least one pair of shock absorbers.
The safety and comfort of a car are important indicators for us to evaluate the quality of a car, and the contribution of car shock absorbers to car safety and comfort is indispensable. First of all, as long as the car moves, the shock absorber is always working. The life of the shock absorber is not like other parts. It can be used for a long time. As long as it does not run on the mountain road, it will basically not cause any safety to driving. It's problematic, but the ride is definitely uncomfortable, there are many noises, and it may cause motion sickness.
Secondly, the shock absorber on the car is not used to support the weight of the car body, but to suppress the shock when the spring bounces and absorb the energy of the road impact. In other words, the hydraulic shock rod and the spring form a shock absorption system. If there is a problem with the shock absorber, the spring will not be able to control the rebound of the spring. When the car encounters a rough road, it will bounce seriously. The vibration caused the loss of tire grip and tracking.
Since the shock absorber is so important in the safety and comfort of the car, its failure cannot be ignored. If a shock absorber leaks oil, it will affect the stability of the vehicle, especially when running on high-speed or uneven low-lying roads, it will feel the car swaying back and forth, unstable, and wind blowing, shaking. If the shock absorber is a new one, if the old one is replaced, its tensile force will be different and uneven. In order to avoid these problems, the safest thing is to replace them all, but at least two should be replaced for economic reasons.
In addition, the life of the shock absorber is about 80,000 kilometers. If one oil leaks, the life of the other three is almost the same. Instead of repeatedly changing it four times, it is better to solve it all at once, which is more economical. And safety first.
