My TO bearing squeaks but it only does it when the engine is cold. It stops after being driven a bit.
If it's your TO bearing, it should stop squeaking as soon as you depress the clutch pedal.
Funny that you mention the tensioner pulley wobbling every time that you hear a squeak. My truck is doing the same thing. Both the belt and the pulley are brand new. As a matter of fact, they have been replaced TWICE! This has been an ongoing problem.
I have it isolated to one side of the engine.
I still suspect that damn tensioner pulley...
Let us know what you find.
