I have:
1989 YJ 6-258 automatic transmissionIn replacing my U-Joints (driveshaft), the grove where the snap ring fits in broke off. It broke off from the grove out, so an actual piece of the metal broke off. About 1/4 of the circumfrence broke off, so the snap ring will hold there, but it pops out easily resulting in premature U-Joint breakdown. This happened on the "Y" shaped part that slides into the transfer case, not the main part of the drive shaft. Normally when I replace the U-joints, I mark all of the parts so that they will line up the same way when I put them back in. If I get a replacement "Y" part, how do I make certain to get it lined up the right way, or is that even an issue? Also, is there an "official" name or part number for the "Y" part? Thanks in advance Richard M. Hinchliffe
