Sorry for not being clearer. The helpful VW person was referring to machining the cast portion of shaft, not the journals. I haven't measured the shaft OD for any out of round yet (not sure I can) but found it interesting that the shaft itself is tapered and that the outer bearing journal OD was ~ 1mm larger than inner. I will likely get at least the outer bearing replaced, or do it myself. Regardless, the bearings look ok and I didn't feel any lateral play. This part does not see a lot of load and doesn't turn that fast.
