Trailing Arm with Mounting Bracket, AWD

Special tools, testers and auxiliary items required

• Torque wrench (V.A.G 1332)

• Mount (T10149)

Removing

- Remove the wheel.

- Remove coil spring => [ Coil Spring, AWD ] Coil Spring, AWD.

- Remove retainer - 1 -, pressing out inner pins of rivets - arrows A -.






- Remove the coupling rod - 2 - from trailing link.

- Remove bolts - arrows B -.

- Unclip electrical wire from mounting bracket.

- Mark installation position of mounting bracket on body.

- Remove the screws - arrows -.






- Remove longitudinal control arm - 1 - with mounting bracket.

If longitudinal control arm is being replaced, mounting bracket must be removed from longitudinal control arm.

- To do so, clamp longitudinal control arm into vise so that mounting bracket - 1 - makes contact at vise - arrow -.






- Remove bolt - 2 -.

Installation position of mounting bracket to trailing link must then be adjusted.

Determining installation position of mounting bracket relative to trailing link

Measure dimension - a - from center of bolt to outer edge of mounting bracket.






Dimension - a -: 57.5 +/- 1 mm.

1. Bracket

2. Trailing link


- When dimension - a - has been adjusted, tighten bolt.

Installing

Note the different tie rod versions when replacing the trailing arm. Refer to => [ ] Tie Rods for Trailing Arms, FWD and AWD, Allocation.

Note the allocation of the tie rods for the trailing arms => [ ] Tie Rods for Trailing Arms, FWD and AWD, Allocation.

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!

- Attach longitudinal control arm and mounting bracket with bolts - arrows - to wheel bearing housing, but do not tighten.






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

- Raise wheel suspension using engine/transmission jack (V.A.G 1383 A) and wheel hub support (T10149) until mounting bracket makes contact on body.

- Tighten bolts - arrows - on old impression.






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

- Install coil spring Coil Spring, AWD.

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






- Tighten the coupling rod nut - 2 - to the wheel bearing housing.

- Install retainer - 1 -, pressing in inner pins of rivets - arrows A -.

- When installing the wires for the electrical parking brake, make sure the dimension - a - between the connector - 1 - and the retainer - 2 - is exact.






Dimension - a - = 150 mm

- Install the wheel and tighten the wheel bolts. Refer to => [ Tightening Specification for Mounting Wheels ] Specifications.

- Perform vehicle alignment => [ Vehicle Alignment Procedure ] Vehicle Alignment Procedure.
