Hi, I'm new to the forum and the Dodge Truck Family. Just learning how to get around the forum. I recently purchased a 2110 Dodge Ram 4x4 Mega Cab Laramie mineral gray. What a nice truck. However, I'm experiencing a vibration throughout the truck between 65-75 mph. The dealers having trouble isolating the problem. Anyone else experience this type of problem or have any solutions.They checked the tires, replaced the rear drive shaft, and the rear housing, pinion, and ring gear. Any advice would greatly be appreciated. I'm confident they'll find the problem eventually.
