Problem Description and Possible Solution
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.
Average mileage: 75,000 (12,000–143,000)

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.
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.
