Sooooo after bringing the truck back to the dealer for the third time, and them balancing the tires and allegedly doing a road force balance, I still felt the vibration and ended up bringing the truck to a local shop. I told the shop that I had vibration issues at varying speeds, and they diagnosed that all tires were out of balance and that I had 2 bent wheels. So much for the quality of a Certified Pre Owned Ram Truck from this dealership!Thanks for all the reply's. Bringing it back to the dealer on monday, they need to figure this out...Stay tuned.
