CV or not CV

[Beatty, Robert]

Most likely front wheel bearing.  Way to test is if the noise goes away when
turning left, it is the left front wheel bearing that is bad.  Turn right
and gets quiet its the right side. Once you think you know what side it is,
jack the car up and take off that wheel and see how that side spins, usually
you can hear it grinding away when you turn it by hand.  CV joints usually
dont make noise at speed, they are more inclined to pop and snap when
turning at low speeds.  To test CV's find a big parking lot thats empty and
roll down your windows.  Turn the wheel to one side to the limit of steering
travel and make a few SLOW circles in the lot.  Repeat for other direction.
If you have a bad CV joint you will hear clicking, snapping and popping
sounds while turning.
