Those failures can and do happen. Once the inner cage breaks the ball are
going where they shouldn't and the van will stop, if you're lucky. I've seen
them jam in such ways to even break the end off the drive shaft and the axle
stub on the differential.

I've never heard of a rear cv on a vanagon failing catastrophically enough
to affect driving.
Generally they just start to clunk when turning one way.
Yep, 1 wheel drive in snow. GOOD snow tires help alot.
Otherwise a 2wd vanagon is "ehh" in snow.
The droning could also be a transmission related issue, such as a failing
Ring/Pinion Gear or Bearing.
Rule out wheel bearings first and change your transmission fluid if you
never have.
