Does anyone have any information or a procedure to change the rear axel seal in my 2001 Expedition? I have a oil leak.

 

I don't think it's a seal -- it's just a bead of silicone grease on the pumpkin cover. Get your hands on a Haynes manual for the 97-02 Expy, it goes into detail on how to remove the cover of the rear diff and change the fluid. Good luck.

 

I think he's talking about the axle seal on the wheel end of the axle, not the differential. Mine has a leak there too and I haven't gotten around to looking at it (along with a list of other stuff) either, but the proceedure would basically go like this:

(This is assuming these are C-clip style axles, which I'm fairly certain they are)
Remove the tire/wheel and brake/rotor.
Open the diff cover and remove the center pin from the gear carrier.
Push the axle shaft in towards the differential.
Pull out the C-clip that's holding the axle shaft in.
Pull the axle shaft out of the housing.
Remove and replace the axle seal (may require a seal puller, but I don't know on these axles).
Put everything back together, fill axle with proper lube.

 

Mine were replaced last summer. Both seals were leaking. They still leak. Dooooooh!

 

This is the axel seal on the end of the axel. The procedure posted by Pitrow appears to be correct and in line with the Haynes manual. The dealer wanted $450 to do the job. I have less than $100 in new E-brakes, oil, seals, and lifetime shocks. I post the results of the job here tomorrow.

 

Thank you for the help. The job was like the procedure in the manual and I completed the entire job in less than 2 hours. Thank you
