When I'm going down the highway at 62 mph and faster there is this horrible vibration throughout the cab of the truck. Oh this is a chevy 2500 HD 6.0 4x4. Other than that there hasn't been any issues. When I bought the truck they said they had replaced the Flwheel about 3 weeks ago. I thought it might be the flex plate not balanced. What elese should I check out?
