Default Vibration Data Logger

Could one of these be useful in diagnosing vibrations in the drivetrain? After the dealer left out my pilot bearing during my engine install, and my driving 500 miles without it, I think my torque tube shaft or bearing is damaged but do not know how to diagnose. The manual shift **** is where I am feeling them. While the installation of a pilot bearing cured the screeching and most of the vibrations some still remain that worry me. I figure if I can log the vibrations I can see if they are rythmic, rpm related, or something else. Am I completely barking up the wrong tree here? I don't know how that data would help me but I am lost as what to do. Just replacing parts until the vibrations are gone seems too hit or miss and too expensive but I can't think of any other way.

The dealer has a PICO test that isolates vibration and since the dealer left out your pilot bushing why are you not taking it back to them to fix as I am confident that this could have damaged the shaft , also setting the preload on the shaft correctly is not only imperative for toque tube installation , if not done right will lead to thrust bearing failure in the engine ....

If I was in your shoes know what I would be doing ....
