How to install shock absorber after Geely Job?

Pacific auto network 1. Stop after driving 10 km on the road with bad road conditions, and touch the shell of the shock absorber with your hands. If it is not hot enough, it means that there is no resistance inside the shock absorber and the shock absorber does not work. At this time, appropriate lubricating oil can be added and then the test can be carried out. If the shell is hot, it is the lack of oil inside the shock absorber, so it is necessary to add enough oil; Otherwise, the shock absorber is invalid. 2. Press the bumper hard and release it. If the car jumps 2~3 times, the shock absorber works well.

3. When the car is driving slowly and braking urgently, if the car vibrates violently, there is something wrong with the shock absorber.

4. Remove the shock absorber and erect it, clamp the lower connecting ring on a vise, and pull and press the shock absorber rod several times. At this time, there should be stable resistance, and the resistance of pulling up and restoring is greater than the resistance of pressing down. If the resistance is unstable or there is no resistance, it may be that the shock absorber is short of oil or the valve element is damaged, so the parts should be repaired or replaced.

After determining that there is a problem or fault with the shock absorber, first check whether the shock absorber leaks oil or has traces of old oil leakage.

If oil leakage is found, first tighten the nut of the cylinder head. If the shock absorber still leaks oil, it may be that the oil seal and sealing washer are damaged and failed, and a new seal should be replaced. If the oil leakage still cannot be eliminated, pull out the shock absorber rod. If you feel that there is a hairpin or the weight is different, further check whether the gap between the piston and the cylinder is too large, whether the piston connecting rod of the shock absorber is bent, and whether the surfaces of the piston connecting rod and the cylinder are scratched or scraped.

If there is no oil leakage from the shock absorber, check the connecting pin, connecting rod, connecting hole and rubber bushing of the shock absorber for damage, desoldering, cracking or falling off. If the above inspection is normal, the shock absorber should be further disassembled to check whether the fit clearance between the piston and the cylinder is too large, whether the cylinder is tight, whether the valve seal is good, whether the disc is tightly attached to the valve seat, and whether the extension spring of the shock absorber is too soft or broken. Repair by grinding or replacing parts as appropriate.

In addition, the shock absorber will produce noise in actual use, which is mainly caused by the collision between the shock absorber and leaf spring, frame or shaft, damage or loss of rubber pad, deformation of dust-proof pipe of shock absorber, oil shortage and other reasons. The cause should be found out and repaired.
