I've wasted my adult life away overhauling everything from Eaton 2 speeds to many tandem axle semi differentials and never drained the oil where the last few drips didn't look like fine metallic paint particles---it's normal with mileage and age. Same with a manual transmission. And if a magnetic drain plug is used, it will always have some metallic "fuzz" stuck to it. Since Ford in their infinite wisdom didn't spec a drain plug in the axle housing, after pulling the back cover to completely drain gear oil it's a good idea to drill and tap a 3/8 or 1/2 pipe plug hole in the bottom of the housing and use a magnetic drain plug for in the future.
