Chasing the cause of vibration...

[SnowDrifter]

More what I'm getting at: does it feel like it's wheel speed? Or driveline speed?

RPM dependent or speed dependent?

Speed dependent for sure. It starts around 60 and stops after 65. Smooth at 70. I haven't gone faster than that. I have put it in neutral and coasted down from 70 to 55 and it vibrates the same way at the same speed. Today I had the tires balanced at hibdon, they said all 4 were a little unbalanced. Thought maybe that was it, until my way home. Same exact vibration.

If you don't have enough experience to feel the difference between driveline and tire, and easy way you can check would be to put the car in the air, support it well, pull the wheels off, put the lugs back on to hold the rotor in place, pop in in 4wd (not auto) and take it up to speed on jack stands

Ya, I definitely dont have the experience to be able to tell the difference. I was thinking about taking it to a chevy dealership or an alignment shop and having them take a look at it.
