Disassembly
Clean the dirt from the suspension strut.
Using a special tool. compress the spring so that its upper cup is unloaded (see fig. 10.14).
Attention. When using a universal spring compressor, make sure that the coils of the spring are securely gripped and that the spring is compressed from three opposite sides. The spring has a very high compression force, so use only a very reliable tool. Never tie the spring with wire.
Attention. The central fastening nut can only be unscrewed when the spring is compressed.
Secure the shock absorber rod against turning with a wrench and, using the second ring wrench, unscrew the central nut of the shock absorber rod.
Remove the washer, top mount, top cup support, collar, and rubber bumper from the shock strut (see fig. 10.15).
If only the spring needs to be replaced. release it slowly. If only the shock absorber is replaced, the spring remains compressed.
Examination
Check all suspension strut components for wear, damage or deformation. Check the smoothness of the shock absorber rod.
Check the shock absorber for tightness. as well as its stem for pitting along the entire length
Assembly
Assembly is carried out in the reverse order of disassembly. At the same time, make sure that the upper and lower ends of the spring are correctly located in the cups (see fig. 10.16, 10.17).
