So I'm back from holiday travels and finally got around to separating the driveshaft and switching out the bearing. One of the CV joints was dry so I was cleaning it out to replace the grease and one of the balls failed. Definitely need to replace the joint, but I'm not finding it anywhere online and ETKA doesn't even list it as a separate part since it's a "non-serviceable" driveshaft. The part numbers on the outer carrier are: "7153120184020 *GKN LOGO* ITALY GKN61 030610 2C*VW LOGO**AUDI LOGO*".

Does anyone know of a source for these? Or am I shit outta luck and need to buy the whole driveshaft?
