Note: Different models may have different coil springs with their own rubber mounts. The spring type is indicated by a red or blue stripe on its last coil, as well as a number stamped on it. When replacing springs, make sure that the new ones always have the same markings as the old ones.
Removal
Remove the rear shock absorber by first loosening its upper mount.
Compress the spring with a spring extractor (the puller should grab 5 turns of the spring).
Remove the rear spring together with the rubber cup.
Clamp the spring in a vice, remove the rubber cup by turning it to the left, and slowly release the pressure from the spring.
Installation
Before installing the spring, check the rubber cup for porosity and damage and replace it if necessary. Clean the contact surface of the diagonal lever. Check if the drain hole is clogged and clean it if necessary.
Place the spring puller on the spring and slowly compress it.
Install the rubber cup (74) and the cylindrical spring (73) in place so that the end of its lower coil "sits" in the recess in the diagonal lever (72).
Slowly release the pressure from the spring, checking that it and the rubber cup are correctly positioned in the body floor and diagonal arm.
Remove the puller.
Install the shock absorber in place, securing it first to the diagonal arm and then to the shock absorber housing (76).
Inspect the buffer (95) for damage and replace it if necessary.
Note: On models designed for heavy loads or with reinforced springs, an additional 8.5 lam spacer disc is installed between the buffer and the body floor. In this case, a longer bolt is used to secure the buffer.
