I just got back from visiting with a mechanic that works at one of the local parts store. He thinks that it is the TO bearing as well. It only has 8000 miles on it. How long do they normally last after they start making noise? Of course there are all types of variables that influence the answer. My concern is I don't have time to drop the tranny to inspect or replace before ZDayz. I actually have another spare Koyo TO bearing and an OEM pilot bushing so I am hoping that it will last until I get back. Any thoughts? Thanks
