1999 Cadillac Seville V8 Front Wheel Drive Automatic 72000 miles
----------------------------------------------------------------
While driving down the highway doing 60 my whole car shimmies, you can feel it through the whole passenger area and feel it in the steering wheel. The engine mounts have been replaced, there are new wheels and tires on it, the front end has been aligned. the brakes have all been replaced the cv joints seem to be ok. We have had mechanics go over it several times but they say they don"t know what the problem is. The shimmy at first seems to be intermittant during the beginning of the trip, but becomes consistant as the trip continues. Under 55 there is barely a shimmy and above 75 the shimmy seems to disappear. Any ideas?[/quote:b0c40ef334]

no not tie rods, new lower control arms, it hooks to your knuckle, you might call them for this(dealer) give them your vin # and suspention code, which is on the board that houses the spare tire, flip it over and you will see it, it on a white peice of paper, belive its an f code, like F5 or something like that, also Vogue tires this is common for them, they are vary hard to balance, you need a special machine to do this, at my dealer we had to send them out to have it done, go back to where you bought them and complain keep doing it til its fixed, I know its trouble, you might just get some new tires out of them depending how new they are
