I have a 91 limited, 4.0, d35 with a factory limited slip. I have only had the truck a couple months, and checked the diff fluid over the weekend while I had it on a lift. The diff was way overfilled with what looked and smelled like ATF. Did the previous owner know something I don't, or should it be gear lube in there? The gears don't whine or grind.
Thanks
