i just got some body work around the right rear tire because of some scratches, but when i got it back i was driving home and at 80 mph i began getting vibrations throughout the whole car and it started to become unstable the more i sped up the more the vibrations and when i slowed down it slowly started to level out. i checkd my tire pressure and thats not it, can any1 help me?

 

Tires might not be balanced. You should check to see if the weights are still on.

And where are the vibrations coming from. The steering wheel, seats...?

 

srry but how would i do that? and i dont really know that whole shell begins to vibrate and the sterring wheel starts to get a lil unstable

 

Your wheels could very well be out of balance as roldy stated above, but if its a really harsh vibration, your tire could very well have a seperation. Get it checked out soon, stop by a discount tire..

 

Check to see if the lugs have been tightened

 

lugs or bad tire

 

If you have aftermarket wheels then you might need hubcentric rings
