Strange subject. Just to add: I also have 2, 2005 models, and they both have LESS slop than my 2013 !!!??? The cush drive rubbers just slip in and out, after you remove the big snap ring, that holds the drive spline in the wheel. I've had them out of all my 3 Rockets, when changing tires/wheels, and have not noticed any wear, either time. I know on some bikes, people sometimes swap the rubber for delrin, or poly, but with the triangle shape of the Rocket cush rubbers, it'd be difficult. I don't think we'd ever get rid of all the slop, but less would be very nice!
