[Vwdiesel] odd CV failure

This is mostly anecdotal. I've had CVs make noise for over 100K and
taken them apart, cleaned, lubed, inspected, and found nothing
observable wrong. I have heard of CV joints catastrophically
failing with no notice. VW, Dodge, Chevy.
My take is that nothing on cars is assured, and CV joints are proof.
I'm glad you were able to make quick work of it. It helps to keep
the bolts on the axle flange unstuck, just for moments like
your friend had.
BTW, I had a CV rusted inside, with water in the boot, and it still
worked. I never tested it to see how much longer. A replacement is
cheap compared to a problem on the road.
