Steering Wobble at 40+ mph

Just wondering if anyone might know what would cause this. Ive got a 94 Camaro. At slow speeds it drives just fine, but as I gradually increase speed (around 40mph), the steering wheel starts viberating form left to right very quickly. Its more annoying than anything. Anyone know what might cause this and how to repair it? I was thinking a wheel alignment and balancing might cure it. Who knows? Thanks. :)

Bad tie rod end, ball joint, possible broken belt in the tire. I would get it inspected fairly soon. Good Luck.

I'd say a bad tie rod, had that happen to me recently

get it checked!!!!! it could be almost anything. like for me a month ago a wheel stud broke, the other lug nuts were lost, and the wheel almost whent flying off while doing 80 on the highway. GET IT CHECK!
