My '06 R/T vibrates real bad between 70 and 75mph on the highway. Less than 15K on the car and all the parts.
I have seen several threads about the Continental tires, car vibration, and rotor warping, wheel balancing, and even brake replacement, but I can't seen to find an answer to my car's vibration.
How do you determine which one is the issue without a shop diagnostic and fee? Doesn't seem to vibrate much when braking, so does that rule out rotors and brakes? I'm sure I am going to have to take it in, but just want to gain some insight before I go. Most places around here charge to even see if the wheels need balancing, so at that point you might as well do it. So unless I can narrow it down to that problem I'd rather not just guess.
Thanks.

My friend had a brand new 06 with high speed vibration. Took it back. They spent hours aligning it and replaced the rotors because he also had a brake judder. He got it back, no change to the hs vibration. Brought it in again. He went to pick it up and they wouldn't give him the car (too dangerous to drive). They called and said DCX said it was defective wheels. He picked it up and the wheels did not look to have been changed. Still vibrated. He took it to a tire shop. They had to use a 4' pipe to loosen the lugs and they found 3 tires GROSSLY out of balance. 4 trips to the dealer over several weeks (He lives in the next state!). The level of incompetence out there is STAGGERING. HS vibration is almost always tire and balance issue. So save the headaches and try a tire shop and wait for the car instead of the old dealer run around.

My father has a 2005 Magnum SE, and when I've driven it, I've noticed something similar at highway speeds: The steering wheel will start vibrating heavily, then gradually go away a few seconds later, then drive smooth for a few seconds before beginning to vibrate again. He's had the tires balanced multiple times, but it keeps happening a short time later. The brakes feel OK; the stops are smooth, and the "bite" gets progressively deeper the slower you go. So is it an issue of crappy tires? If so, then another tire maker needs to make a similar-sized set, because the tires we've had have been lousy, and my father said that the right size tires were hard to find.

Had the same problem, along with a front-end pulling, on my 05 R/T. Classic alignment symptoms. Had it aligned twice, no difference. Still had the vibration when cruising (not braking) so that ruled out brakes. Defective rims is really a long shot.
My mechanic advised that the self-sealing Conti's were probably the cause. Apparantly, this is a problem with all self-sealing tires, where the sealing goo inside heats up and shifts around, causing random pulling symptoms (one day left, next day right), and also out of balance problems. You can balancce the tires, then the sealing goo shifts as you drive around, and they are out of balance.
I ditched the Conti's a few months ago and went to Goodyear Assurance in stock 18" size. Problem solved. No more pulling, no more vibration. based on what you're saying, I would replace the tires before you spend any more time/money on this problem.
