1. The average annual driving distance of a car is 20,000 kilometers, and the shock absorbers should be replaced in pairs, so the replacement frequency is once every 4 years. In fact, the replacement frequency will vary depending on the different vehicle conditions, road conditions and shock absorber manufacturers.

2. For cars, shock absorbers have two main functions: one is to damp the vibration transmitted to the car body due to uneven road surface or poor driving conditions, maintain the smoothness of the vehicle and make the ride comfortable.

3. The second is to quickly eliminate the vibration of the shaft and wheels caused by the road surface, ensure that the wheels can grip the ground at any time, thereby ensuring the steering and braking functions of the vehicle and improving the safety of vehicle driving.

In fact, many car owners do not know how often to replace car shock absorbers, and some people do not even know to replace shock absorbers. In fact, car shock absorbers are consumables and easy to damage. Under normal circumstances, they should be replaced after about 80,000 kilometers. During normal maintenance, the car shock absorbers should be checked for oil leakage and damage every 20,000 kilometers. You must know that a broken shock absorber will directly affect driving safety. If the car has run nearly 100,000 kilometers and the shock absorber has already shown signs of damage, then all four shock absorbers should be replaced.

There is no fixed mileage limit for replacing automobile shock absorbers, because the road is blocked and the load is different, which has different effects on the life of the shock absorber. It depends on whether there is a fault such as leakage.
