I did a search and couldnt find any tips on replacing a rear main on a yj with a 4.0.

I did an oil change on monday and ever since then the thing has been leaking like a sieve (checked drain plug its seated well and its not leaking from there anyway).

I figured my haynes manual would give me the step by step on the seal, but they will probably say something like:

Step 1. Remove engine.
Step 2. Remove tranny.
Step 3. Replace Seal.
Step 4. Do steps 1 through 3 backwards.

If you guys have any advice/writeups on how you did yours, please let me know.

Thanks,
Chris

Well on my 4.0 and the 258 it replaced I just dropped the oil pan and the rear main cap. Then you just take a punch and push the old one out. Make sure you lube up the new one and just slide it in. Know what I mean? <IMG SRC="smilies/wink.gif" border="0"> Then reverse the steps to put it back together. Make sure you torque the cap to specs. I have done this twice and if you get the seal in the right way it works like a charm. The whole process should only take about 2 hours or so. Then it is time for <IMG SRC="smilies/beer.gif" border="0">!
Oh yeah, make sure you put a dab of silicone where the seal halves come together.

Go to Napa or www.4wd.com and pick up the 1 piece oil pan seal. It is real nice and makes putting the pan up real easy. It is worth the $20. There are detailed instructions in the FSM. I have one for a '91 and if you e-mail me a fax number I could send them to you. I will not be able to do it until Fri. though. An even better idea would be for you to get a FSM because it will be the best $100 you can spend on your Jeep.

I agree with joep......drop the oil pan and remove the rear bearing cap. I used a one piece oil pan gasket from the dealer. If it is leaking,I recommend cleaning the engine compartment before you start. It would suck to have all that road grime fallilng in your eyes while you are working. I also replaced the 3 o-rings on the oil filter housing while I was in there. This was on our 91 XJ.

Mine was 35 from the dealer, Napa was out, but it was worth every penny!
