GMT400 but am hoping your GMT800 will be similar/same
This is what the front disc/hub assembly looks like

The four bolts are a $$%$#% to get off and some has to be torched off
because of they rust solid
This is what one guy took time to capture while he tore his 3/4 ton
Suburban front rotor/hubs off.

{edit}....that single nut should be replaced with a new one. Some
shops will reuse, but they are just a couple bucks from any GM Parts
counter. IIRC something in the +200 ft/lb torque range, but best to
look that up
PPS....DO NOT loosen that nut with the full weight of the vehicle
on it...and WORST yet, to roll it...that is all that is holding the
hub/bearings together and the tapered roller will gouge their race...
PPPS...if going this, change the hub assembly too...they are in the $100-$150 per range
