I have noticed that the the rear of my 99 4.0l has been a little wet with oil lately and there is the odd drip underneath. I suspect that the rear main is likely out of it and I was wondering will it get progressively worst? Do you think that a oil overfill could be causing this as I noticed that after my last change the shop put too much oil in (about a half inch high on the dip stick).
Has anyone had any luck with some of the leak stop additives available?
Overfilling CAN cause problems, but unless it was grossly overfilled I wouldn't think that would be it.
The leak stop additives typically cause more problems than they solve.
Monitor your oil level regularly until you can get in there to fix it. It's not a hard operation at all...once you get the transmission out. That's the PITA part. Once it's out it's a really quick swap, and then put the tranny back in.

Zack, can you remember what has to be removed to drop the tranny on a 4.0L?
On some 4.0 engines, the filter is mounted to a cast aluminum adapter that mounts to the side of the block where a filter would normally mount. There is an O-ring behind the filter adapter that can leak also. Oil will come down the side of the block, and can be driven back towards the bell housing by air flow at speed.

No, but you need a rather large wrench to remove the bolt that holds the adapter in place. I think I used a large adjustable. It comes right off, and the O-ring is easily replaced.
