...Had the dreaded rear end binding in my 03 xlt 4x4. Had no idea what it was...but it had been getting worse over the past few months. Slow right and left turns from a stop were rewarded with heavy binding/ vibration that I thought was coming from the front....but with the help of a buddy made me realize it was indeed in the rear differential. In a straight line accelerating during the initial take off a slight binding could also be heard.
...Hit the internet and realized it was the clutch discs in the differential acting up. Picked up 3 bottles of Amsoil 80w90 gear lube, 2 small bottles of the friction modifier from the ford dealership and a rear diff gasket from a parts store and headed up to a buds house. The oil that came out was black and nasty. Dumped both bottles of the friction modifier in first followed by about 2.25 quarts of the Amsoil. Drove 10 minutes to an empty parking lot do some slow sharp figure 8's to help speed the " healing process " up. Took the first turn and the binding was gone. That was yesterday. Put maybe 100 miles on it and it turns nice and smooth.
