Its alright on the streets the problem is on the highway is there anyting that my be loose or worn out that could cause this? The problem occurs around 60 or over I was thinking a alignment and tire/wheel balancing any suggestions?

I would start with rotating tires and if you hit anything hard like a pothole or a curb, get your alignment checked. I slid into a curb one winter and it jacked up my alignment. I burned through a set of tires in 15,000 miles and the car shook bad at high speeds

Does the steering wheel shake? Or the whole car? Could be any number of things. I'd try rotating tires to narrow it down...like Cappuccino911 suggested. Or save all the hassle and go to gsp9700.com and find a location near you with one of those machines. They can spin your tires up and correct just about any vibration.

Could be a loose / improperly torqued lug nut too. I had a vibration problem before, all I had to do was re-tighten the lugs.

I agree with the rotation balance- start there...if it persists have ur alignment checked. With it ocurring over 60 I am believe you prolly just need a good balance and rotation.
