Vibration on deceleration
about 1500 miles, I noticed a vibration and whine when I let off the accelerator above 75 mph, but it stops @ 70 mph. It sounds like a differential or transfer case whine. Any one with similar problem or ideas. Thanks in advance.
By the way my 02 250 7.3 4x4 was a great truck, but this one rocks!!! as my 14 year old daughter would say.
