Judging the quality of the shock absorber based on the performance of its internal components
1. Remove the shock absorber and stand it upright, clamp the lower connecting ring on the vise, and apply force to pull and press the shock absorber rod several times. At this time, there should be stable resistance, and the resistance when pulling (restoring) upwards should be greater than that when pressing downwards. If the resistance is unstable or there is no resistance, it may be due to a lack of oil inside the shock absorber or damaged valve parts. Repair or replace the parts
2. Check the gap between the top glue. After driving the car for 2 to 3 years, as long as the gap does not exceed 1cm, it is considered a normal fluctuation. If the distance between the top rubber exceeds the normal fluctuation range, it indicates that there is a problem with the shock absorber.
3. Observe whether the appearance of the shock absorber leaks oil, whether the dust cover buffer block is damaged, and whether there is eccentric wear or corrosion on the surface of the piston rod. Any of these three situations indicates a probability of failure of the existing shock absorber.
