If the shock absorber does not leak, check the bushing to see if it is damaged, unsoldered, broken or detached. If the above check is normal, should be further decomposed shock absorber, check whether the fitting clearance between the piston and cylinder is too large, a cylinder with and without strain, valve seal are in good condition, whether the disc and seat nicely, and whether the presence of shock absorber spring is too soft, or broken, according to check the shock absorber connecting pin, connecting rod, connecting hole grinding, rubber, the circumstance or change a way to repair.
In addition, shock absorbers in practical use will produce a sound of the fault, this is mainly due to shock absorbers and steel leaf spring, frame or shaft phase collision, rubber pad damage or fall off and shock absorbers dustproof tube deformation, insufficient oil and other causes, should find out the cause, to repair.
After the shock absorber is inspected and repaired, the working performance test should be conducted on a special test bench. When the resistance frequency is 100±1mm, the resistance of its stretching stroke and compression stroke should meet the requirements, indicating that the shock absorber is basically normal.
