Removing and installing wheel bearing housing Special tools and workshop equipment required

t  Torque wrench -V.A.G 1332- Removing –  Remove wheel. –  Remove coil spring → Chapter. –  Remove wheel bearing/wheel hub unit → Chapter. –  Remove splash plate. –  Remove ABS speed sensor out of wheel bearing housing.

–  Remove bolt -arrow-.

–  Remove bolt for track rod -1-, upper transverse link -2- and lower transverse link -3- from wheel housing -4-. –  Remove coupling rod -arrow- from wheel bearing housing.

–  Hold wheel bearing housing and unscrew bolts -arrows-. –  Remove coupling rod -1- from trailing arm. Installing

–  Install bolts for track rod -1-, upper transverse link -2- and lower transverse link -3-. –  Attach coupling rod -arrow- to wheel bearing housing hand tight.

Threaded connection for trailing arm and wheel bearing housing may be tightened only after all other components (particularly the spring and shock absorber) of respective wheel suspension have been installed. To tighten, wheel suspension must be in extended position. Only then do trailing arm and wheel bearing housing move to the necessary position -arrows-. It is important to keep to the specified sequence for the following operations.

–  Position trailing arm and mounting bracket on wheel bearing housing using bolts -2- but do not tighten yet.

–  Install bolts -arrows- and tighten to prescribed torque. –  Install splash plate. –  Install wheel bearing/wheel hub unit. Bolt connections on wheel bearing housing may be tightened only when dimension „a“ has been obtained → Fig..

–  Tighten bolt for track rod -1-. –  Tighten bolt for lower transverse link -3-.

–  Tighten bolt -1- for upper transverse link.   Note Washer -2- must be installed so that there is a gap -arrow B- between washer and splash plate -3-.

–  Tighten bolt -arrow-. –  Install coil spring → . –  Install ABS speed sensor in wheel bearing housing. –  Install brake disc. –  Attach brake carrier with brake caliper → Brake systems; Rep. gr.46. –  Install wheel and tighten bolts or nuts → Chapter.
