Removal and Installation

Front Wheel Drive (FWD)

Trailing Arm with Mounting Bracket

Special tools, testers and auxiliary items required

• Torque wrench (V.A.G 1332)

• Mount (T10149)

Removing

- Remove wheel.

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

- 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 bolts - 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 - is 57.5 ± 1 mm.

1. Mounting bracket

2. Trailing link

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

Installing

CAUTION!
Note the different tie rod versions when replacing the trailing arm. Refer to => [ Tie Rod Characteristics ] Application and ID.

Note the allocation of the tie rods for the trailing arms. Refer to => [ Note the allocation of the
tie rods for the trailing arms ] Application and ID.

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 -.

Position: Threaded Connection of Trailing Link/Wheel Bearing Housing





• Always follow the order of the following work steps!

- 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 (V.A.G 1383 A) and (T10149) until mounting bracket makes contact on body.

- Tighten bolts - arrows - on old impression.





- Let down wheel suspension again using (V.A.G 1383 A) and remove (T10149) from wheel hub.

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

- Tighten bolts - arrows B - for longitudinal control arm to tightening specification, observe required position of components while doing so.





- Tighten nut for coupling rod - 2 - to 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 wheel and tighten. Refer to => [ Tightening Specification for Mounting Wheels ] Tightening Specification For Mounting Wheels.

- Perform vehicle alignment. Refer to => [ Wheel Alignment Overview ] Wheel Alignment Overview.
