Hej GM bulletin beskriver problemet för årsmodellerna 2005-2009

Supercede:
This bulletin is being revised to add the 2009 model year. Please discard Corporate Bulletin Number 07-04-95-001 (Section 04 - Driveline/Axle).
Condition
Some customers may comment on a tapping or a scraping noise coming from the rear wheel area.
Cause
This condition may be due to the torque on the wheel drive shaft nut relaxing over time.
Correction
Replace the left and the right wheel drive shaft nut following the procedure below.
1. Remove the center cap from the rim.
2. Remove and discard the wheel drive shaft nut.
3. Apply LOCTITE(TM) 272 or equivalent to the threads of the axle shaft.
4. Install the nut (P/N 10257766) and tighten to the new specification.
Tighten
Tighten the nut to 215 N.m (160 lb ft).
5. Install the center cap to the rim.
Important: The vehicle should not be driven for 24 hours following the repair in order to allow the thread lock to cure.

33mm, 1 5/16", or 34mm socket (whatever works for you). I will say that the 34mm socket will work with the 1 5/16" and 33mm nut, but a 33mm socket probably won't work on a 1 5/16" or 34mm nut.
