Position: Threaded Connection of Trailing Arm/Wheel Bearing Housing






Threaded connection of trailing link/wheel bearing housing must only be tightened when all other components (spring and strut always) of the respective wheel suspension have been already assembled. To tighten, suspension must be unloaded. Only now do the trailing link and wheel bearing housing move into the position required - arrows -.

- Install coil spring. Refer to => [ Coil Spring ] Coil Spring.

Always perform the following work in the sequence given!
