I have a 2007 SE AWD with a little of 4,000 miles on it and have had whining from the rear end. They have inspected the tires, ball bearing, and recently determined it was the rear end. Ford directed a whole rear end stump to be sent from the factory and did not want the dealership to even open up the rear end, and wanted to inspect it themselves. They replaced the rear end, and now I have a roaring still. It get most noticable at 40 mph and over (louder). Going into dealership on Wednesday to speak to service manager and another guy to drive and show them. I have called Ford and told them I am wanting them to replace it because of this.
