Rough Ride on a 06 Quad Cab

I have a 2006 4x4 Quad Cab HEMI Ram and I have had a bumpy ride almost like the tires need to be balanced since I have owned it. I have taken it to about 4-5 dealerships across the country to fix this problem and they have had no success. The dealerships have tried everything from replacing the rims, balancing the tires, checking out the suspension system, and now I took it to another dealership and the service mananger flat out told me that he has had numerous Rams come in with this same problem and they have taken the apart and put it back together and havent been able to fix the problem and also told me that a couple of the customers actually had there trucks purchased back by Chrysler. He said that I probably wouldnt be able to sell my truck back to Chrysler because I have owned it for over 12 months and the NC lemon law where I currently live wouldn't apply. I bought my truck in Arizona and I am not familiar with there laws, but I need to do something about this problem. Does anyone know a number or a way to contact Chrysler about this problem or should I just call a lawyer and ask them what they could do?

Thanks for all of the advice and help......

All that info is in the manuals that came with the truck. Most people don't look at them though. Tell the dealer you want to talk to the DSM.
