This job is a walk in the park. A couple tips that seem to make it easy. Undo the for bolts that hold the mount to the floor frame. Lower the diff to remove the back plate, and raise it back up again to remove the axle. Remove the brake caliper by undoing the two bolts. You don't have to undo the hydraulics. REMEMBER to fish out any spacers used to set up thrust on the axle and transfer to new axle. The job is so easy with the caliper out of the way.
