Mark -- The external wiper arm fits onto a splined shaft.  Probably due
to not tightening it down enough, I managed to strip a wiper arm and
saw something similar to what you have, but it was a gradual process.
Sounds more like something's come loose between the motor and the
wiper arm in your case... but it's been so long since I've looked
in there... Bentley shows a couple of 'relay rods', so it's possible
that one of those has somehow popped off...
