Installing

Installation is the reverse of removal, with special attention to the following:

Position: Threaded connection of trailing link/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 Coil Spring, AWD.

Always perform the following work in the sequence given!

- Place trailing arm on wheel bearing housing with screws - arrows - but do not tighten yet.






- Insert coupling rod - 1 - in trailing link, do not tighten nut yet.

- Let down wheel suspension again using engine/transmission jack (V.A.G 1383 A) and remove wheel hub support (T10149) from wheel hub.

- Tighten bolts - arrows - for longitudinal control arm to tightening specification, observe required position of components while doing so => [ Position: Threaded connection of trailing link/wheel bearing housing ].

- Connect the coupling rod - 1 - to the wheel bearing housing and stabilizer bar.

Bolting at wheel bearing housing may occur only when the dimension between wheel hub center and lower edge of wheel house, has been attained => [ Measure dimension ] Rear Suspension.

- Install brake carrier with brake caliper.

- Tighten the driveshaft bolt to wheel hub:

• Twelve-point bolt with ribs, refer to => [ Twelve-Point Bolt with Ribs, Loosening and Tightening, Driveshaft Threaded Connection ] Twelve-Point Bolt with Ribs, Loosening and Tightening, Driveshaft Threaded Connection

• Twelve-point bolt without ribs, refer to => [ Twelve-Point Bolt without Ribs, Loosening and Tightening, Driveshaft Threaded Connection ] Twelve-Point Bolt without Ribs, Loosening and Tightening, Driveshaft Threaded Connection

Vehicle must not rest on wheels when doing so.

With screw loosened, wheel bearing can be damaged by the vehicle weight.

Differences between a twelve-point bolt with ribs and a twelve-point bolt without ribs






The contact surfaces - arrow A - and - arrow B - are different on the two-point bolts.
