Hey thanks guys. I'll try and get a picture. As I look at it, the movement is where the axle and the bearings go through the outer carrier. There appears to be a large nut on the outside (not the cassette side). If this is an adjustment nut should I try tightening it? I used to have some good bike connections but they are no longer. And I haven't really gotten my hands dirty on bike repair and building. Good with cars not with bikes yet. But again thanks for all the ideas.
