Wonder if a room temperature urethane such as Flexanehttp://www.markingpendepot.com/browseproducts/Devcon-Flexane-94-Liquid.HTML could be used to repair them. It is available from many suppliers, comes liquid or putty, in various hardness ratings, and maybe could be poured around ball if suspended properly. I used the stuff to make new body mount bushings and thinking it might be an option on these rather than sending off.
