Kent,
Can you give a short summation on how to remove the differential on my 82 sd? I recently purchased one that howls very loud, and the previous owner supplied one with the car. I do have a car lift, tranny jack, tall jack stands. Just looking at it, I would unbolt it from the body, lower it, drain out lube, take rear cover off, remove axle clips (Pin), remove rear wheels, loosen axle nuts on hub, and go from there. Any help is appreciated. Thanks, Bill
