When I hit 55mph and above , I notice a slight vibration in my drivetrain. If I let off the gas, say at 65 and let it coast, once I come down to 50 mph, the truck rides smooth, vibration goes away. It`s not really all that bad but it`s noticable. What`s the problem? The dealer had it 2 times for the issue. 1st time they said tires needed to be rebalanced so they took care of that. Well, no go. 2nd time they said tires are choppy due to lack of rotation (thx to previous owner) thats the reason for the vibration. Well, no go. I replaced the tires and its not as bad but it`s still there. Also on these cold mornings, when I drive down the street it feels like I have a flat spot in my rear tires until the drivetrain warms up then it`s fine. I think the problem is in the trans. What about the rest of you? What do you think? Help. Thanks.
