Based on the average annual mileage of a family car of 20,000 kilometers, the shock absorber can be used for 5 years. The shock absorber of the car needs to be replaced after driving about 100,000 kilometers. If you usually drive on some roads with better road conditions, it can prolong the service life of the shock absorber.
As far as normal conditions are concerned, vehicle shock absorbers do not have a stable service life. As long as the shock absorber does not leak oil, and the internal vulcanized rubber is brittle and cracked, it can be used all the time.
Naturally, after the vehicle has achieved a certain service life, it is indispensable to regularly maintain the operation of the shock absorber (generally, when the vehicle mileage reaches more than 100,000 kilometers, it should be checked regularly).
