Get the friction modifer from Ford. Oh, and make sure you buy a synthetic gear oil. I had Royal Purple in my truck for 50K, and just switched to Lucas oil. Both were/are great.

First, what differentials do you have?

It's a 2000 F-250.. There's only one set he can have. Dana 50 up front, Sterling 10.5 in the rear.

if you go with aftermarket covers, most increase fluid capacity. also, if you use a good synthetic oil you may not need friction modifier(i didn't using some amsoil i had left over from something else)

How often do you change this fluid and how do you know it needs to be changed?
I have a 99 F250, do I have the same differentials?
