How do I change the rear differential fluid in the 2003 ford explorer?

The process to change Your 2003 Ford Explorer's rear differential fluid is quite simple; all You'll need is a 1/2 inch drive ratchet, a 3/4 inch drive ratchet, and replacement 75W-140 differential fluid. Perhaps, of course, a little bit of patience -- things like this always seem to go wrong, at least for me! I tend to plan out an afternoon and maybe have a few beverages in the meantime. Anyway, You'll need to put Your Explorer up on jack stands and access the rear differential cover. On top, there's a fill plug that can be removed with the 1/2" drive, and a drain plug at the bottom that can be removed with the 3/4" drive. Remove these to drain, replace the drain plug, fill, replace the fill plug, and You're as good as new!
