Do I have a worn diff?
How can I check for a worn diff, and ring pinion gear. If i turn each drive cup side to side on the rear diff (with fresh fluid), it has a "geary" feel, unlike a totally fluid feel of my other two. Is it a sign of being worn out?
also, when free spinning the diff in the gear box, i get a deep "gear whine" noise that I do not get out of the front. the gears look pretty decent. Are these worn?
