When the shock absorber of a car is damaged, it is necessary to replace a pair of shock absorbers. If only one shock absorber is replaced, the damping on both sides will be different, which will affect the car's handling and balance. If possible, it is recommended to replace all four shock absorbers at the same time. Shock absorbers are a type of consumable part that needs to be replaced regularly. They are mainly composed of shock absorber and spring, and controlled by the damper to limit the number of spring bounces. Without damping, the car will have poor comfort and handling on rough roads. It is important to purchase original products and seek professional assistance for replacement. If low-quality shock absorbers are used, it may cause the car to run off course and even cause abnormal tire wear. Without timely replacement, shock absorbers may also lead to oil leaks and increase the risk of accidents.
