Call and talk to Jeff @ JJ and A. If it is for sure a JJ and A axle he will help out. Do you have the original hubs? Or is it a full Fireball axle? If you have a JJ and A setup and they matching hubs are loose, he would probably warranty that. You will have slight play however due to the system utilizing the hub setup with pinch bolts. The hubs have to be able to slide over the 40mm shaft while the pinch bolts are loose.
