Rear main seal leaking-short cut fix?

I thought there was a way to snake the old one out and pull the new one through without separating the engine and tranny (auto tranny) 05LJ. Is that not correct?

Yes, pull the oil pan, bearing support and rear bearing cap. You may also need to remove the exhaust to completely drop the pan.

Try some Valvoline Maxlife oil first. Worked on mine and the leak has not returned.

Its really not, took me about 4 hours casually. I would fix it the right way and you can learn something about you jeep while doing it. It never a bad to check and insect a few things like timeing chain, bearing play or just looking for metal in the bottom of the oil pan.

The hardest thing was trying not to make a mess so my wife wont get pissed off.

I think there are a few videos online as well about RMS and jeeps.

It can turn into a really long job if you do what I did:

-Tried to get the exhaust off so I could drop the oil pan
-Couldn't unbolt the exhaust from the headers, so I had to grind out the bolts
-Had to remove the intake manifold to get to the exhaust bolts
-Since the intake manifold was off, and it shares a gasket with the exhaust, pulled the headers off as well to replace the gasket
-Since the headers were off, decided to clean, paint, and wrap them with exhaust wrap (as well as the Y-pipe section of the exhaust)
-Cleaned out the intake manifold (which was surprisingly grimy)
-Replaced the oil pump since I had the pan off anyway
-Replaced oil pan gasket since I had the pan off anyway
-Not at all related or required, but since the Jeep was off the road anyway I pulled the skid plate and stripped and painted the skid and the center section of the frame

All told my Jeep was off the road for about a week. I was between school and work at the time too, so I spent every day working on it. Turned into quite a project just to replace a leaky RMS.

Nah, my days of crawling under a jeep are mostly over. Bad neck and a pulled back is also a problem. Not to mention the mess. My wrenching is limited to my KTMs.

i remember reading the 4.0s there was a way to do this.

Did you read the link provided? That's the way to do it. Yes, you don't have to separate the engine and transmission, but you do have to drop the oil pan which involves getting some things out of the way (e.g. starter, exhaust).
