4.0 rear main seal is 2-piece, not one. Tranny does not have to come
off the replace it and it's definitely not a $400 job. Took me 2
hours to change mine - and half od that was getting the old pan gasket
off so the new one would seal. Pay attention to the advice - put a
rag behind the rear of the engine under the valve cover and see if
that's where the "rear main" leak really is. That's a lot more common
than a rear main (mine was over 150k before it really did start to
leak).
