Grinding at 71 MPH
I have a grinding sound when im goin down the highway but only happens within a 1 or 2 mph range right at about 71 or 72. I would think a tire is out of balance but its a grind not shake and you can usually feel those at half the speed in the wheel. also when im taking a corner and mostly when im on a corner and hit a bump where the truck gets some movement it can go to a real hard rough sounding grind. also grinds when accelerating hard through 71. already replaced any u-joints needing it. could the drive line just be off a little or any other ideas?
