CV axles wouldn't do that. I hope they were bad for other reasons. Is this vibration felt through the steering wheel, the entire car or what? The thought that comes to mind is motor mounts. I would be checking the motor mounts. Check them one at a time. Using a partner, I would run the engine and watch as the car is put in to gear forward and backward while accelerating with the brake on. The engine will try to move and you should be watching for excessive movement at the mounts.
