The gimbal is tight, compass dance completed, changed out one motor that was acting up.....bit still have the high frequency shuttle/vibration.
What might I try next? Should I do an advanced calibration?

Yes. Do an advanced IMU cal and then closely inspect your props for and wobble, distortion while hovering. You haven't changed the gains by any chance have you?
Can you recommend a good balancer from amazon or ebay,possibly a name of the balancer ? ThanksIrishSights said:Check the screws that hold the gimbal to the shell. Part of my regular maintenance.

ianwood said:Your gimbal and P2 are in a feedback loop. If you ever saw the movie Gravity, you'll know that when one thing moves anything attached to it is going to move as well. Something has changed in the frequency in which your P2 or gimbal correct their balance. It could be the rubber balls or it could be a gain settings.
Sledge said:That makes sense, but I don't think I changed anything (same dampeners, etc.) when the vibration arose.
I have balanced my props with the dubro balancer and used 2 different sets just to make sure that wasn't it.
The only gains I have ever changed is the X1 tilt gain. (to the best of my recollection)
Here is a video showing the vibration: http://youtu.be/ei-spF8iYK0

Yep. That's a feedback loop. I would focus on the gimbal mounting. Don't fly for long like that.
