Slight "vibration" at over 65mph??

[radtech]

Seems when I'm on the highway at 65+, my car vibrates slightly. Not much, but when the windows are up, you can detect it somewhat easier. The steering wheel doesn't vibrate at all. Car has sat at times before I got it. The tire shop said the tires were okay without flatspots. Any ideas??? Thanks guys!

driveshaft? it's an idea... maybe pull it off, rotate it 180 degrees and see if that helps. You can get it balanced...

radtech huh? You by chance an HP or RP? If you don't know what I'm referring to you probably aren't!

Did tire shop re-balance tires, maybe a wheel weight

Tire shop said tires were ok. Maybe I'll have a shop check my driveshaft for balance. Thanks guys. Radtech is for radiology tech (aka x-ray tech).

Bad shock?

Is it engine RPM, or MPH related?

 

[radtech]

Shocks are relatively new. No suspension issues to speak of. RPM isn't a factor as I can put car in neutral at 65+ and car still has the vibration.
