The holes in the cradle which the yoke bearings slide into and to which the yoke is attahed has become so worn, there is alot of play which prevents the driven disc from maintaining good contact with the steek drive disc. I have replaced most of the drive train parts, however, it will never work right unless I can somehow get a tighter fit with these nylon bearings. Do they make oversize bearings for this issue or does anyone know another quick fix for it. The cradle is part of the main case and cannot be replaced.
