Question rear main seal replacement

need some advice. i am pretty sure my rear main seal is leaking after 138,000 miles on the 4.6. there is oil on the front of the transmission.

my question is, is this seal replaced like the 5.0 by any chance? dealer here wants $500 to replace it, but i would rather do it if i can. not interested in removing the engine!

thanks in advance for any help.
Ben

Hi Ben and welcome to FTE
What year is your truck?
Did your dealer check it out and say it's the rear main seal?
A more common leak would be a head gasket. Usually that can be seen above the starter.
To replace the rear main seal it is much like a later model 5.0.
You have to remove either the engine or transmission

racerguy,
no i haven't had it to the dealer yet. i will crawl back under and look around the starter. i just say the oil near the rubber plug on the bottom of the auto and thought of the rear seal. it is a '99 xlt.

so i just remove the transmission, pull the old out, oil up the new one and slide it back in? no oil pan removal or anything else?

That's pretty much it.
There is a special tool to install the seal but if you're careful you should be able to install the seal without it.

Racerguy,
I've got a 2001 Supercrew(small V8) and I'm not sure if the seal is my problem. I'm losing oil, not smoking, grayish residue on the Oil cap when I screw it out. I get a sputter on light excelleration. I've been told it's the main seal but they recommended I sell the truck as opposed to fixing it. Of course I was weary of that answer, but it did not come from a Ford Dealer because they usually charge so much just to analyze. Any thoughts?
