There is no "bind" on the rear axle shafts of a "full floating" rear axle. The load is carried by the hollow spindle portion of the housing. The whole idea of the full floating axle is to take the load off the axle shafts so their only job is to propel the vehicle. Axles can be removed with the truck sitting on the ground and fully loaded and the effort to remove them is the same as if the truck is on a jack.
The axle shaft/shafts could theoretically have some torque bind on them if the truck is in gear and on an incline, leave the trans in neutral, block the wheels, pull the shafts. The drums/hubs will come off after you remove the wheel bearing nut, washer, bearing.
