Front End Vibrations

I have a new '02 Seville. When I'm on the freeway and going between 65 and 75 the front end of the car vibrates. I've had the tires balance twice and even rotated and balanced again and there is still a vibration. I have the michellin symmetry tires. I have heard that the rotors might be poorly balanced and they may need to be replaced. Anyway, if anyone has had this problem or know of someone who has had this problem with a seville please let me know, and what the problem was and how it got fixed. Thank You!!

I have a 2001 Seville STS and I am having a similar problem. however, my front end doesn't dhake, my seats in the passenger cabin vibrtate. This happens on smooth pavement at betweeen 65 and 80 mph.

I saw there was a technical bulletin abou this Here is the link if you are interested.

I am at a loss as what ot do . I had new tires (michelin)put on, balanced by tiure dealer, balanced by cadillac, yet I still get vibration.

There is a fix out there which involves engine mount and control arm bushing changes. The tires are not the problem, so don't waste your time changing tires. If i can figure out a service bulletin number I will post it.
