Help. CV joint or bearing. Whomp whomp sound on acceleration.

And if the wheel bearings are bad they could allow a camber change. So a
wheel alignment is good to do anyway afterwards! ;-)

I usually guess which wheel bearing is bad and then double check it by
removing all components off of the hub and then spin it by hand to confirm
it is bad.
