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.
same issue, but whining is loud and starts from take off at zero. have been told it is the rear axle. never heard it before, bought it at 55k miles and started at 143k miles
At speed i can hear the pinion support bearing howling. I can vary the degree of noise by either accelerating or decelerating. If i "float" thru the rpm range at a particular speed, i can make the sound go away.
Repair was not made because the mechanic at auto nation dodge was either deaf, lazy or "new". He could not find /hear the problem.
