Think its driveline now

Cancelled on the wheel re-balancing, I am sure it is drive line. Vibrations are too inconsistent in how much and when it happens. My tranny shifts too hard randomly as well, maybe it is a center support bearing issue, or a diff bushing issue.

Strangest thing was I jacked up all 4 whees to check for play with the wheel bearings, and then it drove with a lot less vibration, but as it warmed up it came back. So probably the rubber part warming up loses its rigidity and then it vibrates again. What a PITA.
