Cushion rubber and dust cover of automobile shock absorber are commonly known as "shock absorber repair kit", and as the name implies, they are accessories that should be used when the shock absorber is repaired and replaced.
However, in practice, many repairmen are reluctant to use new accessories, and there is the idea that small accessories don't matter. After replacing the new shock-absorbing movement, they still use the old buffer glue and dust cover of the original car.
The material of cushioning glue is polyurethane foam, which has cushioning and anti-impact functions, but it has a service life, and it will crack, break and become powder after the service cycle.
When the vehicle is running, the shock absorber moves up and down, and the piston rod moves up and down with it, resulting in high temperature, and the powder of the buffer glue will stick and burn, which will further scratch the oil seal and lead to oil leakage, abnormal noise and other problems, shortening the service life of the new shock absorber.
Therefore, it is suggested that when replacing a new shock-absorbing movement, the cushion rubber and dust cover should be replaced together to avoid rework and the above failures. Of course, the best choice for replacing the shock absorber is to replace the shock absorber assembly.
