I try to keep my mouth shut but your safety is at stake here. If you don't know how many lug nuts your truck has I doubt that you have the equipment needed to safely support the vehicle while your legs may be under it.

It is (as stated by the OP) the rear axle under a 2500HD. I'm fairly certain that it has 8 lugs.
If he doesn't know that, I wonder if he has the expertise to properly clean, lubricate, and adjust the bearings.
