i'm not sure, but if there is any slack in the wheel it is not a good sign. it could be that the little slack that is there is enought that, over the 24" or so diameter of your wheel, it could make the wheel look like it is out by an inch. i would definately adjust the tension on your bearings and replace them if needed. they don't cost that much. i think i paid $25 canadian for the inner, outer and seal.
