1959 Vibration at 60 MPH

[PaulB]

I tool my car out on the freeway for the first time this year and i had a slight vibration when i reached 60 mph. I hadn't noticed that before. I put new tires and rims on the car over the winter but they were installed and balanced by the tire dealer so i can't imagine it would be that. Any other thoughts of what it might be? Alignment maybe?

Possibly a bad universal joint.

Yup, They will act up a certain speeds. Sometimes at 30MPH will disappear when you get up to speed then again at double the speed. Bad tires will do the same. Vibrations at certain speeds. Harmonic resonance in play.
