WARNING: This page does not describe the selected car, but rather 17 other vehicles, including the 2009 Audi S4, 2009 Audi A4, 2008 Audi S4, 2008 Audi RS 4, and 2008 Audi A4. However, it is still accessible from the selected car via links, so may be relevant.
(Adjusting differential)
Special tools and workshop equipment required
- VW 385/17 Magnetic plate 50 mm dia.
- VW 387 Dial gauge holder
- VW 388 Measuring lever
- VW 521 Adjustment tool for ring gear
- V.A.G 1331 Torque wrench
It is necessary to readjust the ring gear when:
Final drive housing, cover for final drive, taper roller bearing for differential, differential housing or drive pinion are replaced.
Adjustment overview. Refer to Adjustment overview
NOTE:
- Differential taper roller bearings are low friction bearings. Therefore the frictional torque only has a limited use as a check. Correct adjustment is only possible by determining the total shim thickness "Stotal".
- Do not oil new taper roller bearings for frictional torque measurement. The bearings have already been treated with special oil by the manufacturer.
