I posted this on the GM Board the other day but only had one reply (thanks Mr. Ed).
It seems that the rear main seal is starting to fail. After getting back home the other night I noticed way too much oil on the outside of the tailgate.
Also I noticed a lot of oil on the power steering reservoir and the engine. So, I removed the inspection plate so I could see the flywheel....and more oil!
Has anyone changed out this seal and what's involved in the process.

Thanks,

First of all, are you sure the oil is coming out of the engine rear seal or is it coming out of the front seal of the transmission? Changing either seal is not hard, on the rear main you may want to use a ring spacer to avoid riding on the worn grove (or go oversize with a sleeve), and be sure to put in a left hand seal. You'll need a slide hammer with a screw end to remove the old rear seal.

"First of all, are you sure the oil is coming out of the engine rear seal or is it coming out of the front seal of the transmission?"
The reason I'm thinking engine seal Geoff is because I rarely add transmission fluid compared to engine oil.
I'll probably be getting the seal from Luke ggypsy.
Thanks guys.

You need to find out which seal//
Take off the body part below the tranny door disconnect all the clutch and gear shift rods. Go underneath and take off the frame /engine cradle strut that goes under the tranny. Get a large cantelever engine lift and a chain( I used two floor jacks one heavy 3 ton under the tranny bottom, I made a large flat plate to replace the small round one. then I used two belts around the tranny to secure it. the second floor jack I put under the angle drive and put belts around it.)
Then you unbolt all the bolts around the bell housing lift slightly up on the jacks and she will wiggle stright out. you can the unbolt the clutch from the flywheel and see the main seal.
You may have to unbolt the flywheel, in order to pull the seal///maybee???
My wife and I can take are tranny out in 4 hours. but I have done it twice before.
Let me know when its time to go back and Ill walk you thouh it.
Does your bus jump at all when taking off in 1st gear or in reverse?

Thanks John. This will probably take place sometime in December. I sing with a gospel group, and we'll be off for the month.

Oh yea, that's something else I'm gonna address at the same time. LOL
