i have a high speed problem in my firebird, when i get to 50mph my car starts to shake and its to terribly bad but once i hit 80mph+ it feels like its going to fall apart the passenger seat is shaking back and forth and the dash is floping and feels like the steering is shacking and its scary. i would take a video to show of it but at that speeds with the wobble its Frigen scary.

i mostly drive in the city but when i get on the highway i get scared.

What could be the Problem? all i can think of is maybe a wheel is bent? Front wheel bearing?

 

Get your wheels balanced. Also how old are your tires? cuz if they have been sitting a while they may have flat spots. just a thought

 

oh also the Tires are fairly new and they were ballance recently.

but if the wheel was bent i dont think they would even tell you because they just dont care
