Give me some ideas on how to diagnose drive shaft vibrations inside the torque tube besides a teardown and critical inspection.
Thanks!
Depressing the clutch pedal decouples the propeller shaft from the clutch assembly. If you experience vibration while reving the engine under this condition, the source of the vibration is most likely as a result of an imbalance in the pressure plate and or flywheel. Additionally, depressing the clutch pedal loads the clutch release bearing and allows the pilot shaft to rotate within the pilot bearing.
Releasing the clutch pedal couples the propeller shaft to the clutch. If the drive line was not vibrating under the previous conditions and is now vibrating the imbalance is most likely in the propeller shaft. Depending on the nature of the imbalance in the propeller shaft, it may not vibrate as much while reving it in neutral since it's not under a load.

let us know if this is not the vibrations you are experiencing. I went through this ordeal for a long time and found out I had a bent rim causeing it.

Thats ONE OF THE BEST explanations on this issue that Ive see in a long long while!
