How to maintain and service a 6R0413031 shock absorber?
Shock absorbers are wear parts during use of a car, and their performance has direct implications for smooth drives and the life cycle of other parts. Hence, they should be always kept in well functional status.
In order to test the performance of a problematic shock absorber, the car can be driven for about 10 km on a bumpy road. After stopping the car, feel the enclosure of the shock absorber with your hand.
If it’s not hot enough, the shock absorber probably lacks internal resistance and is not able to work properly. In this case, an adequate amount of lubricant may be added before starting a second test.
If the enclosure is well heated after the second test, the problem of the shock absorber can be addressed by sufficient lubrication, otherwise it may have failed. During inspection of a shock absorber, press down the corresponding bumper with force and then release it.
If the car bumps twice or three times, the shock absorber is in good condition.
If a car vibrates violently in response to an emergent braking action in low-speed status, something is wrong with the shock absorber. To further identify the nature of the problem, remove the shock absorber and put it in upright position. While holding the lower connecting ring with a bench clamp, pull and press the shock absorber rod for a couple of times forcibly. A steady resistance should be present, and the resistance felt when pulling it upward should be higher than that felt when pressing it downward. An unsteady resistance or lack of resistance probably indicates insufficient oil in the shock absorber or a damaged valve part, and corresponding repair or replacement should be performed.
After discovering a problematic or failed shock absorber, first check if it has exhibited any old or new signs of oil leakage.
In the event of a broken oil seal or seal washer or loose screws of an oil tank, the failed oil seal or seal washer should be replaced. If oil leakage persists, the shock absorber should be pulled out. If the absorber fails to move smoothly or the load changes in this process, check if the gap between the piston and the cylinder is excessive, if the connection rod of the shock absorber piston has been bent, and if there is any scratch or pull mark on the surface of the connection rod and the cylinder.
If no oil leakage is found on the shock absorber, inspect different parts of the shock absorber including the connection pin, connection rod, connection hole, rubber, and sleeve to determine if there is any damage, loose weld, crack, or detached part. If no defect is found, the shock absorber should be further disassembled to check other abnormal conditions, including excessive gap between the piston and the cylinder, pull mark on the cylinder, poor valve sealing, loose contact between valve disc and valve seat, and too soft or broken draw spring of the shock absorber. Repair, polishing, or replacement should then be performed depending on the actual problem.
Noise generated by a shock absorber during use may result from collision between the absorber and plate spring, car frame, or car axle, a broken or loose cushion, deformation of the dustproof tube of the shock absorber, or insufficient oil. The root cause should be identified to enable proper repair.
A repaired 6R0413031AT shock absorber should receive performance test on a dedicated test table. At a resistance frequency of 100±1mm, if its extension travel and compression travel are in line with relevant specifications, the shock absorber can be considered functional.
