Heres my 2 cents for what is is worth. As easy as it is to pull the motors on these trucks, I would just yank the motor, bellhousing and tranny as a unit and get it out where you can work on it. If that rear seal leaking, likly it needs all gaskets replaced, except maybe the head gaskets. The engine may be dirty and the engine bay may need cleaned up anyway. It really does not take that long to yank one out, versus many hours on your back under the truck with no room, with crap and oil dripping all over your face. I've done it both ways and I vote for pulling on these.
