Default vibrations

I am getting vibrtions and loud noise when go over 80k. Had the car 3 years and it always vibrated now it seems to be getting worse. Half shafts are ok. My thoughts are main drive shaft and universals. Or maybe the rear end. Any ideas. Thanks Randy

Please spell that out a little better.

80K ???

That either means 80,000 RPMs or 8000 RPMs. One is impossible and the other is super dangerous for a street motor.

What RPM are you saying it starts vibrating at?

80 KPH / 50 MPH ???

Sounds like its time for a front end alignment. You could always jack up front end and checkout all components for obvious wear and check tires for damage. You may be lucky and only need a wheel balancing.
