Don, thanks. I just went to the garage to compare the bushing to the bearing that came with the kit, and I noticed a very strange thing. The bearing that came with the kit, has an outside diameter that is quite smaller than the bushing that is inside the shaft. Hmmmm. So, for now I MUST leave the bushing in. I will do as you suggested, and tell ya what I find.
If it is worn a bit, what is the worst that can happen?
