Shock absorbers are too important for some of you who often drive on rough roads. If the shock absorber does not work properly, it will lead to a reduction in the life of the parts of the car! And also greatly reduce the smoothness of the car driving, sitting in the car personnel will also feel quite uncomfortable bumps. Then the car shock absorber is usually installed in the car suspension system. Remind everyone to check whether the shock absorber can work properly before going out, especially when you have to pass through a lot of uneven road surface for a long distance. Here is how to check the efficiency of the shock absorber.

1. First, you can drive at a low speed, and then brake sharply, if you find that the car shakes more, and the human body feels uncomfortable, then the shock absorber has a problem.

2. Press the bumper hard and then release it, if the car has 2~3 jumps, it means the shock absorber is working well.

3. Make the car in the road conditions of poor road surface driving 10km after parking, with the hand touch the shock absorber shell, if it is not hot enough, it means that there is no resistance inside the shock absorber, the shock absorber does not work. At this time, you can add the appropriate lubricant, and then test, if the shell is hot, the shock absorber internal oil shortage, should add enough oil; otherwise, the shock absorber failure.

4. Remove the shock absorber and set it upright, and clamp the lower end of the connecting ring in a vise, and press the damping rod several times, there should be stable resistance, and the resistance should be greater than that of the downward pressure, such as unstable resistance or no resistance, it may be a lack of oil inside the shock absorber or the valve parts are damaged, and the parts should be repaired or replaced.

Then oil leakage is also one of the reasons for the shock absorber not working properly.

If there is no oil leakage from the shock absorber, then the shock absorber connecting pin, connecting rod, connecting hole, rubber bushing, etc. should be checked whether there is any damage, de-welding, rupture or detachment. If the above checks are normal, the shock absorber should be further disassembled to check whether the piston and cylinder clearance between the cylinder is too large, the cylinder has no strain, the valve seal is good, the valve valve and the valve seat fit is tight, as well as the shock absorber extension spring is too soft or broken, according to the situation to take the grinding or replacement of the method of repair.

If you find that the shock absorber rattling fault, this is mainly due to the shock absorber and steel plate spring, frame or shaft collision, rubber pad damage or fall off, as well as the shock absorber dust cylinder deformation, insufficient oil and other reasons.

The above four methods can effectively test whether the shock absorber is working properly. The first method should be used as little as possible, because frequent hard braking is likely to cause damage to the brake system. The second method of pressing the bumper is more recommended to try. And it is very convenient, the effect is also very obvious. In the usual long-distance before, should also check whether the shock absorber has the phenomenon of oil leakage, if there is also cause in the halfway shock absorber work in the source of failure.
