I think that you might refurring to the nut that holds the brake drum on. really there is no real torquing... when I take that nut off and put it on I just use plyers and tighten enough by hand and then make sure that it flows freely and not to tight... the carter pin holds and stuff holds the nut in place and that washer (cant think of what the water is called) but that keeps the nut from turning as well.
Axle torque specs are as follows: Axle nut torque..............148Ftlbs
On the trans, where the pass side axle shaft comes out.
rear axle nut is 65 ft/lbs
180lbs per the spec
175 foot pounds
173 FT. LBS.
175 ft/lbs
175 ft lbs

first torque to 136 ft/lbs, spin the hub by hand 5 times, re-torque to 236 ft/lbs
Once you slack the axle, there should be adjusters to tighten up, just make sure the wheel is even, and torque the axle nut back to spec's.
Axle nut torque specs are 170-203 ft.lbs
