Shock absorber strut - disassembly and assembly

Disassembly

Using a screwdriver blade as a lever, remove the protective cap.



Using the tool, compress the spring so that it moves away from the top. When using a special device for compressing springs, make sure that the spring coils are securely gripped and compress the spring from opposite sides (see picture).



Secure the shock absorber rod with a wrench to prevent it from turning and, using a second wrench, unscrew the shock absorber rod mounting nut.



After removing the washer, remove the upper bushing.

Remove the upper strut support.

Remove the upper spring cup.

Remove the upper bushing.

Remove the sleeve, shock absorber cup, protective cover, and compression stroke buffer.

Using the spring compressor, remove the spring.

Check the smoothness of the piston rod movement during full compression and extension. The rod should move without jerking or jamming.

Note: The rear shock absorber must have a greater extension force (A) than compression force (B).

Check for oil leaks through the rod seals and welds. The stem must not be deformed or damaged.

Assembly

If installing a new spring, compress it with the tool and install it on the shock absorber.
