Elective maintenance - About 100 miles away from 10K miles on my 25' ST. I Changed the front diff. fluid and the transfer case fluid on Saturday. Changed the rear diff. fluid yesterday. How nice of Ford to put the rear diff. fill plug and a cross brace just over an inch apart from one another..
I wanted all the "break-in" drivetrain fluids changed since I've made a few trips from Michigan to West Virginia to ride the HMT trails with my ATV's and dirt bikes. I Pull close too, or at the max GVWR and GCWR on these trips in the steep mountains with my trailer and interior totally loaded. When you're going on week long trips like this you take everything including the kitchen sink with you.
The front diff. fluid was pretty black and smelly with the normal fine particles on the magnetic drain plug. The transfer case fluid looked brand new and the rear diff. fluid looked surprisingly clean with not much particle wise on the magnetic drain plug.
