If you can still drive the car, have someone sit in the back seat and see if the noise is in the rear or the front.
When my rear diff went, I swore the whine was coming from the tranny. The noise travels up the driveshaft to the tranny.
I pulled the tranny and had it opened up to find nothing wrong that would cause that noise. My buddy said pull the rear diff, it must be bad.
