replacing rear main seal

[johnwaynejeep]

I need to replace my rear main seal. I got the general idea from the Haynes manual. Does anybody have any suggestions that would make this job easier or problems I should look out for. I have an 85 GW with an AMC 360 and a TF727 tranny. I have never done this before so any suggestions would be greatly appreciated.

Thanks guys

johnwaynejeep,
I wound up having to drop the exhaust Y-pipe in order to easily remove the oil pan. Naturally I broke off 2 of the manifold studs so I had to remove the manifolds in order to drill out the broken off studs so new studs could be installed. you'll need a brass rod to tap out the old oil seal.Follow the instructions carefully for installing the new oil seal.I had to replace my exhaust pipe anyhow,found some small holes in it. Also it helps if you have the use of a 3/8" drive torque wrench and a 1/2" drive one as well. If you run into any problems just holler. I did all this on my 87 GW and more.
good luck,

Thanks for the help, I'm gonna try to tackle this over the weekend. With any luck I'll get my transfer case working too and then I can try to break something else when I go to the woods.

When I worked at an auto parts store we used to sell something called a sneaky pete made by Lisle.

Lisle tool catalog (http://www.lislecorp.com/tools/catalog/engine/index.htm)
I never used one but a guy who I worked with thought they were great.
good luck

Be sure to use a brass rod. A steel rod can easily damage your crank. I couldn't completely remove my oil pan but I managed to move it to the side enough to work. Afterward the danged thing still leaked. It was late, I was 100 miles from home at my brother's place so I figured I'd just have to do it all over again. I stopped on the way home about 50 miles out and had to put in some oil. Another 25 miles and I put in some more but not as much. When I got home, I didn't need any more oil and its been good since then. So, if it still leaks when you finish, give it some miles before you decide to try it again. It is a time consuming job and not real pleasant, but not difficult. Just be sure to oil it up real good before you install the new seal. It will burn up on the crank if you don't.
Now my front seal leaks :( that's this weekend's job.
