I think I have a bad CV joint, but since I've only experienced this in
front-wheel drive cars, it doesn't sound quite like I expect. What do
you think? Recording here, enjoy my son's and wife's commentary :-)

Notes:

* Doesn't seem to happen until I've been driving a few miles.
* Even walking beside the van I can't tell if it's front or rear
wheel. Passenger side.
* One sound per one wheel rotation, except when it skips a rotation,
or goes away for a while, which it often does.
* No apparent relationship between turning and sound (not at all like
FWD CV). Seems a little more frequent when accelerating. Maybe.
* You can feel the click when riding in van.

Thanks,
George
