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.
