Whining Noise at Freeway Speeds From Rear of Vehicle on Chrysler Aspen

A whining noise heard driving at freeway speeds (more than 55 mph) can be normal noise from the rear axle which is being transmitted through the body. A body/frame damper is available which may help with this concern.

problem details
2008 Chrysler Aspen - 2WD 70,000 mi,
78,000 miles and whining noise started about a year ago. One dealer said it was inherent in the vehicle. Now a second dealer is also telling me the problem is inherent after replacing the drive shaft (which was under warranty) and the noise is still there.

Above 60mph a varying whiny noise can be heard ... not at lower speeds. The tone varies slightly depending on summer or winter tires. Dealer has suggested a rear differential rebuild.
2008 Chrysler Aspen - 2WD 40,000 mi,
Whining/humming sound at 45 mph up to about 65 mph when gas pedal is pressed. When coasting, the sound goes away. Having the pinion gear in the differential replaced, which supposedly will fix the problem, or so the Chrysler dealer tells me...glad it's under warranty.
