When I took the wheels off I didn't notice any problems. I think the outer bearings might be the difference. I will check them later. If I recall I had to get them from two different sources. I have a third set of bearings, but they are not barrel roller bearings like the other two, it is a tapered roller. Wonder is I should try installing that one.
