I keep seeing "one side loose", though have not read all threads. Are the axle threads opposite rotation? In other words are the threads designed so that the rotation of the axle is designed to tighten, not loosen, the nut?

Ok, then on the right side, which rotates clockwise, if the nut also tightens clockwise, the natural rotation of the axle will tend to loosen the nut. The nut on the right side should be designed to tighten counter clockwise.

The hub is splined at the connection point. It looks like the nut just keeps it firmly locked down on the splines.

Just checked mine (05 MN6 Coupe with 9600 mi.). Driver's side required about 1/4 turn to tighten/torque, passenger side about 1/8 turn. I bought my deep socket at Autozone - tried 33mm, 34mm, and 1-5/16" before buying - the Great Neck 33mm, $13.95, works just fine, for what it's worth. Thanks for the thread, guys!

I used the Pep Boys 33mm Axle nut socket and it fit perfect, $12.99, the sockets package said fits many GM applications. Both nuts were either only a little loose, maybe 10-15 degrees of rotation on both sides to tighten, or my Torque wrench is slightly out of calibration. I have an 06 with 9500 miles.

I think they only make a 3/4" drive 1-5/16" regular socket, so you would either have to purchase a 3/4" drive torque wrench (if they make one) or a 1/2-3/4" adapter along with the socket (which I think was $17 or $18 and the adapter is about $5). If you think you truly need a 1-5/16" socket (looks like quite a few here are getting by just fine with 33mm, which you can more readily find in 1/2" drive), then you might check Autozone or Pepboys (assuming you have one of these near you). Autozone for sure carries a 1-5/16" socket, but it is not a deep socket, and I think it sells for under $15 (might even be under $10). HTH.

I bought a 33mm at Pepboys. It was VERY tight to get on. I used a rubber hammer force it on and to get "marks" on the inside to see where the fit was incorrect. It turned out to be the "black" coating on the socket that was being a snot. I put a cone stone on the Dremel and buffed out the black and the fit is perfect.

I checked a guys axle nuts on his 05 c6 this weekend at the track and the drivers side was 1 complete turn loose and the passenger side was 5 turns loose
Very scary since he tracks the car a couple times a month.

Sorry.... Beelzebub made me say it!
It's still a fine picture of the object in question!

Chevy probably wasn't aware of the problem until it was first posted in the Z06 Forum here. Give them a year to go thru committees and bean counters and it'll be fixed.

Thanks for the pic
Now for those of us who are not as mechanically inclined quite SIMPLY
(If it aint' broke don't fix it) these 2 axel bolts need to be torqued to 118 lbs and when checking them the torque wrench should be used to back off first then to 118lbs? It's that simple?
What should I put on my shopping list when I go down to Sears? size of tools needed??.
I already have a torque wrench to tighten the 5 lugnuts on each tire can that be used? I don't have wrench with me now so I can't remember size....
