Well if you think it is drive train related - have you checked oil / fluid levels?

Don't leave that there - I'll take it to bits!

All checked and good.

Just jacked car up and and ran through the gears and got the noise, waiting for additional person so I can get under car to find the source of the sound. Is there a test to determine if this is the Throwout or Carrier bearing once I am under car? I will check the Center Support. Check back soon.

If when depressing the clutch pedal ( engine running) the sound changes volume or tone it is most likely the throw out bearing.

Great, that test rules out the TOB. Sound does not change when engaging or disengagement of clutch.

Sound varies only with speed only.
