Note: You will need a spring compressor to perform this operation.
1. If there are noticeable signs of wear on the struts or coil springs (fluid leakage, loss of damping ability, chips, cracks), then think through all the options before starting work. The struts are non-repairable parts and therefore if any problem occurs they need to be replaced.
Warning! Disassembling the rack assembly is a dangerous operation and all precautions must be taken when performing it, otherwise serious injury may occur. Use only high quality spring compressors and carefully follow all instructions from the manufacturer of the compressor. Once the coil spring is removed from the strut assembly, set it aside.
2. Remove the stand (see section 2).
3. Secure the stand in a vice. Line the jaws of the vise with wooden blocks or rags to prevent damage to the stand; do not tighten the vice too much.
4. Install the spring compressor according to the manufacturer's instructions (see illustration). Compress the spring until it is possible to rock the mounting assembly and spring plate.
3.4. To disassemble the strut assembly and the coil spring, it is necessary to have a spring compression device
5. To unscrew the shock absorber rod nut, hold the shaft with a special wrench (see illustration).
3.5. After compressing the spring, unscrew the shock absorber rod nut
6. Disassemble the rack (see illustrations) and arrange the rack parts in the order shown in the illustration.
3.6a. Remove the bearing cover... |
3.6b....and the upper spring plate with the insulator from the shock absorber axle |
W.bv. Remove the compressed spring. Be very careful when handling the spring |
3.6g. Rack details: 1 - support cup, 2 - upper spring plate, the edges should be directed in the same direction as the lower flange at the bottom of the strut, 4 - cushion, 5 - cover, 6 - upper spring gasket, 7 - spring, 8 - lower spring plate, 9 - shock absorber assembly and strut, 10 - lower spring gasket |
Caution: When removing a compressed spring, lift it very carefully and place it in a safe place, such as a steel box. Stay away from the ends of the spring!
7. Check the rubber parts for damage, cracking or loss of elasticity and replace them if necessary.
8. Assembly is carried out in reverse order. Be careful not to damage the shock absorber rod, otherwise the strut will leak. When installing the spring, make sure that the ends of the spring fit exactly into the installation locations on the upper and lower spring plates.
