Measuring frictional torque (check)
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.
- Pinion shaft removed
- Differential installed with shims "S1*" and "S2*"
- Install torque gauge 0 to 600 Ncm -A- onto differential.
- Read off friction torque.
Frictional torque specified values:
| New bearings | Used bearings 1) |
| 150 to 300 Ncm | 30 to 60 Ncm |
1) With at least 50 km service
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.
- If the final drive set is being re-adjusted, the adjustment of the pinion shaft should be performed now, and the adjustment should be checked. Refer to Drive pinion, adjusting .
