While I had my Muncie out for some Clutch work, I decided to replace the gaskets in my tranny and basically just take a good look in there to make sure that everything is all right. When I took the front bearing retainer off, I noticed that the bearing did not fit tight in the case at all. I can rotate the bearing (the outer race, not the inner) freely and I think that it has been rotating during operation. Should the bearing fit like this? Does the bearing retainer hold everything in place, or is my case just shot?
