At speeds between 50 and 70 mph vehicle has excessive vibration that seems to be from the rear of the vehicle. Had tires balanced by a tire shop and problem persisted. Dealership replaced all four tires and wheels and the problem still persists. Informed dealership of tsb sb-16-001-1, which is exactly the problem I have. They informed me they've never heard of the tsb. Similar to other complaints filed and researched concerning rear vibration issues with 2015 Ram trucks.
