Finally after 4 years and 45K miles its gone. The only thing I can think of that the dealer did different is when I got it back it had 10 more miles that when I left it. I think the tech went and drove it and got the tires warm then road forced balanced them. Who cares! no more vibration.

 

Or replaced the bushings in the steering.

 

I could see the new weghts

 

Been having this problem alittle on mine also, nothing too bad, but hopefully they can fix mine also.
