Car shock absorbers are disposable. Once they are damaged and fail, they need to be replaced. In addition, shock absorbers have a certain lifespan and cannot be used continuously until they are completely damaged. So how often should car shock absorbers be replaced? Everyone has different driving habits, road conditions, and the degree of damage to shock absorbers. Generally speaking, replacement is required after 80000 kilometers or 5 years.

Firstly, replace the shock absorber after 80000 kilometers or 5 years.

Many components of the car above are not lifeless, and so are the shock absorbers. Not only is it damaged and needs to be replaced, but it also needs to be replaced when its lifespan is reached. So how long does it take for a typical car to replace its shock absorber? The specific replacement time is determined based on the degree of damage to the shock absorber. If there are no special circumstances, the shock absorber of a car is usually replaced every 5 years or 80000 kilometers.

However, the actual replacement time of car shock absorbers is not fixed, as everyone's driving habits and road conditions are not exactly the same, so the degree of damage to the shock absorbers also varies. Therefore, it is necessary to determine the replacement time of individual shock absorbers by observing the degree of damage to the shock absorbers.

1、Method for determining whether the shock absorber is damaged.

After driving for 10 kilometers in poor road conditions, touch the shock absorber housing with your hand. If it is not hot enough, it indicates that there is no resistance inside the shock absorber and the shock absorber is not functioning. At this point, appropriate lubricating oil can be added. During the test, if the casing heats up, it indicates a lack of oil inside the shock absorber. Just add enough oil. Otherwise, the shock absorber is damaged and ineffective, and needs to be replaced.

2. Place the car on a flat surface, press down firmly on the bumper (or front), and then release it. If the car only jumps 2-3 times, it indicates that the shock absorber is working well. If it jumps repeatedly, it indicates that the shock absorber is damaged and ineffective, and needs to be replaced.

3. If the car vibrates violently during slow driving and emergency braking, it indicates that there is a problem with the shock absorber.

4. Remove the shock absorber and keep it upright, clamp the lower connecting ring onto the vise, and push and pull the shock absorber multiple times. At this point, there should be a stable resistance, and the resistance to pulling up (restoring) should be greater than the resistance to pressing down. If the resistance is unstable or there is no resistance, it may be due to a lack of oil inside the shock absorber or damage to the valve components, which require repair or replacement.
