Besides that I can't think of what else it could be with my knowledge as the diff should be a set size from manufacture.


Those bearing shouldn't really be popped out as they are only sold that way. If you need new bearing you just need to buy the corresponding replacement part. Sadly every car over had has been like that. Would shimming the area help?
