Joe & Bob The bearings in my nose wheel are rough when installed. Its new, never used. I pushed them out and they feel good. I tried to buy new ones locally and was told that were non-standard. I would like to replace them with cone bearings also. Will I have to modifi the wheel or can I buy the races that size?
