I changed my cover awhile back as well and went with mobil 1 75w140 LS diff fluid.
I found out that my rear cover was leaking a bit not from rust but from the differential contacting something and raising a lip in the cast metal on the bottom causing the leak.
So after filing down the hill and doing all the work and installing new cover I took the old cover which (was still good) and used it to replace the rusty cover on our 94.5 F250.

Another question, I see you guys are doing this on different year excursions and 250's but will this also work on a 2000 Ford Excursion? Google research is saying it will but not 100% sure

Yes it will, whether you have the 10.25 or 10.5 rear. You're good to go. Carry On Wayward Son...

Should be a good weekend project.
Ordered everything on ebay. With the cover and 4 liters of Royal Purple 75w-140 price will still be on under $150 with a new gasket and some Permatex Ultra Black, bolts, etc.
4 Liters Royal Purple (Ebay Item #281207108410) $72.29
Permatex RTV Gasket (Ebay Item #271245979142) $4.59 + Shipping
Aluminum Diff. Cover (Ebay Item #300550951896) $53.83
FEL-Pro -Gasket (Ebay Item #350840960213) $7.24
10 Pack of Bolts (need 12 total) (Ebay Item# 231085796889) $8.14
Doesn't have anything to do with Differntials but for $185 a piece I ordered two new Optimas D34/78 (ebay item # 190965601058)
Also got a new Driver Side Window Motor for $30.
I love saving money and ebay is my #1 place to save right now. Also they have ebay bucks which gives you 1-3% back on all your purchases. All of the items above have more available if anyone else was looking to do this project.

It is an easy shade-tree mechanic job to change out the fluid and reseal the cover. But very messy till I used the manual pump...forget about just filling with the bottles! Mecdac stopped by with Rudolph and talked FTE for a while.
