When I bought my truck, the tech who did the prep said, "this one vibrates". Yeah so did my last three. It's a Cummins. Like Harleys, they vibrate. First trip out on the interstate, he wasn't shttn. So I returned to the dealership where they rebalanced my tires. Now I had a tire vibration along with the origional vibration. So I had the normal 2100rpm engine vibration, a higher frequency pulsating vibration, and a tire vibration. A TSB came out for the 2100rpm normal vibration to isolate it from the steering wheel. The weighted hydro boost hose works great! The dealership swapped drive-shafts with another truck and cured the pulsating vibration that started very slightly at 45mph and was bad at 65mph. Now I've got the tire vibration. The dealership rebalanced the tires two more times. When they rotated the tires, the vibration seemed to go to the rear of the truck.
Point is, there seems to be more than just one cause of vibrations in the new Dodges. There's a fair amount of arguing on other sights about what it is and what it ain't. If you think it's a drive shaft vibration, take a hose clamp and strap a small bolt or something to the shaft. Drive around the block and see what a drive shaft vibration feels like. It comes on soon and is a higher frequency than tire or axle vibration. It's spinning 3,000rpm on the highway while tires and axles are spinning 700rpm there about. It's a different feeling. If you think it's motor or the dealer is telling you it's normal motor vibration, run up to 70 on the enterstate and slip it into neutral and coast down through the vibration speeds. If it still vibrates, it ain't motor. If it's not motor and it seems to come and go from day to day, it's probably tires. They get into different positions each time out and can be worse or better in relation to each other each time out. That and I don't think the dealer's tire guys are all that good. We had the tires balaced and rotated on our Durango and now it vibrates. We'll be taking both to Goodyear for a rebalance to see if we can cure the vibration on both of them once and for all.
