transfer case=?????
front and rear diffs.=?????
Thanks
Front diff takes a 75W-90, 5.7 pints (get 3 quarts) also to the bottom of the fill hole.
Rear diff takes a full synthetic 75W-140, 6.9 pints (get 4 quars) and maybe some friction modifier from Ford.
Here are some excellent how-to links from one of our members, complete with pics and exact specs.

I use full synthetic fluids in my truck, and my personal preference is Schaeffer's fluid, but it can be hard to find. Go here to see if there's a retailer in your area: http://www.schaefferoil.com/dealer_locator.html If there's not, it will give you an 800 number to their home office where you can call and find a rep who can get it for you.
