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.Google+

Similarly, my 2WD 2005 Durango has a whining noise about 60-70mph and when I let up on the gas pedal to coast the noise goes away, push down on the pedal can hear immediately.

Does not matter how fast I am going I start to hear as soon as I take off from 0.

i have the same problem but mine doesnt sound like its near the back its around the middle so i thought it may be the transmission but im not sure and havent felt like doing anything about it yet haha it sounds like a jet plane taking off every time i enter the highway
I hear a high pitch noise only after 60mph on the freeway and lets up after I take my foot off the gas. Whats the problem?
