I have the same problem as the guy in Texas. Once it started going over 60 mph the front right would shutter. Took it in today to check alignment/rotate tires, etc.. They asked if the car was wrecked...nope why? The back tires on the inside wall were down to the thread...I said how...they said it's like the axle is bowed. They re-aligned it and have a call into Chrysler because they've never seen this before. I call bull sh*t on this one, there is something big time wrong with this...How does an axle bow down? They are one piece...You'd have go off a cliff upside down to do this... The guy in Texas stated that they blamed him for towing to heavy a load...bs..now way....I think this problem is going to be bad news for Chrysler...I'll update you when the call back

I bought this vehicle during cash for clunkers, it had 6,000 miles on it. Started having a bounce in the right front tire over 60mph. Took vehicle to dealership, they told me it needed a front end alignment and due to problem it had warped back tires and one had steel belt showing through tread. Went to dealership where purchased and their diagnoses was that we had towed something too heavy with vehicle. Either way it is OUR fault not theirs and now I have to buy new tires for a vehicle I have had 4mo and only has 14000 miles on it. Is it just me or does this sound fishy?
