The noise/vibration associated with the CV cups that I am familiar with is during acceleration, particularly out of right hand corners.

If you have a mid to high frequency noise (whine rather than thump) abouve a certain speed I doubt it is the CV cups. Sounds more like bearing noise. Wheel bearings, diff bearings, secondary case bearings are all suspects. Also, it could be crown wheel and pinion noise from your diff, but this will get worse and then fail.
