Hi,
Das Thema hatten wir hier schon mehrfach.
Das aktuellste TSB gibt ein Anzugsmoment von 215 Nm vor (unten zitiert unter 1). Auf eine Anfrage in Bowlinggreen wurde einem US C6 Owner allerdings ein Anzugsmoment von 190 Nm angegeben (zitiert unter 2). 160 Nm sind definitiv zuwenig.

This condition may be due to the torque on the wheel drive shaft nut relaxing over time.

Remove the center cap from the rim.
Remove and discard the wheel drive shaft nut.
Apply LOCTITE™ 272, or equivalent, to the threads of the axle shaft.

I used the Owner Feedback at
https://www.bowlinggreenassemblyplant.com/
to ask about the Axle Nut issue.
I received a reply and asked for permission to post the fix on the forums. The information I received is as follows:
If there is presence of the nut "indexing and/or looseness", do the following:
1. Remove existing nut
2. Apply Goodwrench # 12345493 (also known as Loctite 272) on threads in area where nut finally seats
3. Install new nut (p/n 10257766)
4. Torque nut to 190Nm (140 ft-lb), static
5. Allow 24 hours cure time.
Update 9/13/2007
Part Number 12345493. has been superceded by 89021297.
