WARNING: This page is about a different car, the 2018 Audi S7, 2017 Audi S7, and 2016 Audi S7. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
the pre-tension on the left flange shaft ball bearing must be optimized only on certain vehicles. Refer to the table for a list of the vehicles. Refer to Installing .
This is not necessary on vehicles built later because they have been redesigned.
- The left flange shaft is removed. Refer to LEFT FLANGE SHAFT, REMOVING AND INSTALLING .
Conditions For Optimizing:
- The bearing bracket does not show any traces of wear or material erosion.
- Small indentations near the hole on the bearing bracket -arrows- are permissible.
- Bearing bracket with wear pattern "A". Refer to LEFT FLANGE SHAFT BALL BEARING PRE-TENSION, CHECKING (the bearing bracket does not shown any traces of wear or material erosion).
- A shim is inserted into the bearing seat on the transmission to optimize the pre-tension on the ball bearing.
-- Insert a Shim :0B4 409 227 -1- into the bearing seat on the transmission before installing the flange shaft to improve the pre-tension.
-- Install the left flange shaft. Refer to LEFT FLANGE SHAFT, REMOVING AND INSTALLING .
