my rearend is whining more than your ex-wife

Isn't there a whining noise from your rear end when you have your rear end mounted at the wrong angle to the driveshaft or transmission or something? I really have not a clue about rear ends or transmissions so I may not know what I am talking about. But I think there was a recall for the new Jeep Grand Cherokees because they had a problem with the angle that the rear ends were mounted so it was making them whine. Not sure though...
