The truck has a violent vibration, you can feel it while sitting in the drivers seat the steering wheel and also the steps getting into the truck, pretty much the whole CAB vibrates. Truck was taken to Peterbilt in Plainville, MA and upon three and half weeks of them trying to diagnose the issue for the third time we were told by Peterbilt that this was acceptable. We are a Fuel Oil Delivery Company, we are worried that the vibrations can cause loosening of truck components that could affect the integrity of the truck and casing failure while driving.
