I have a 2006 Harley Ultra Classic with a CSC Daytona trike kit on it. I noticed recently when checking things over, a very slight movement movement when I grab the top and bottom of the rear wheel and try to wobble the wheel. It isn't the wheel to that's moving, it's the hub. I tightened the nut on the shaft and I can still feel a slight wobble. Is this normal or is it the bearing on the wheel hub?
