I have a front left wheel shimmy --- its shaking at very low speeds, and if i'm creeping(5mph or less), I can feel the vehicle moving side to side. I know its coming from the front left.

When going highway speeds, it shakes VIOLENTLY --- I already put a new tire on the front, and test drove it, it still does it.

I just purchased new rotors and pads yesterday.

Could it be a warped rotor?

The vehicle doesn't shake more or less when braking --- it actually helps the problem since its reducing the speed.

Possible wheel bearing? I did notice my ABS light is on. I lifted the front of the vehicle and used my hands to try to move the tire vertically --- I got no play.

I also tried pushing in at 12 and 6 oclock to test for wheel bearing - I ddint' get anything; however, I did notice a little clicking/clanking sound yesterday. It was very slight. I had to have my music off and windows down to hear it.

Also, its getting worse as time goes on. I did notice that it shakes worse at highway speeds if I hit a bump.

Right now, I can barely go over 40mph without an extremely violent shake. Have to avoid the highways.

Thanks a lot man. I'm going out of town for the weekend with a different car. But i'll check as soon as I get back. I really appreciate your prompt response.

Update: Now that I think about it, the shaking wasn't TOO bad until wednesday when I put air in my two front tires --- then it got extremely worse.

Man, I don't knwo why i'm just now thinking about this. Its great to not have to end up spending money.

Thanks man. It was definitely a cord separation in the right passenger side. I just threw my spare tire on and took it for a test drive - it drives great once again.
