Anyone who can resolve this issue, will be a genius! When I get the truck up to the 75 mph range it will vibrate in the rear of course making the seat in the cab vibrate.
No it is not caused by needing the tires rotated and balanced, did that. While pulling a trailor get this, it does NOT vibrate. This is a 94 3500 5 sp 3. 55 gear, #6 plate. There are 270,000 miles on truck. Someone surely has this answer.
