It's a one piece. I have never done a one-piece while it's in the truck but I would think a case of beer, a cherry picker, and a slew of bench racers might be a better weekend then trying to change it under the truck.
Just my 0.02
On a difficulty level meter, 1 being easy 10 being farm it out...I would say it's an 8 . But I'm sure someone around here might beat me with a 6 or 7.:D

1 peice rear main seal, Just pull the tranny and have at it.

One of my friends just got geared up to R+R the rear main on his 97 Chevy. He got under there and after CLOSE inspection he found it was just the pan gasket...much easier.
Maybe you'll get lucky to??:rolleyes:

Also seen the back of the intake manifold leak (or the older oil sending units) do a nice job of looking like a rear main seal leak. :D

the other thing to check. is if it has a oil cooler the o-ring on the adapter above the oil filter gets hard and leaks down the bellhousing cover and makes it look like a rearmain seal leak.

It is leaking thru the bell housing so I figure it is the rear main or the rear pan
won't know till I really get under to see
thanks guys

Dont drop the tranny! If you want to save a lot of time pull the driveline & get some 8 or 9" bolts & slide the tranny back. get in there with some air & pull the flywheel. then you'll be ready to work. If you do it this way you can do it on the ground in about three or four hours & not have to worry about making too big of a mess. You wont need to pull the converter either.
