alternator squeals with new bearings. What else?

[Konstantin Bogach]

Over weekend I confirmed that sound comes from alternator.   There are no signes of belt movement on the pulley (rubber marks) and no wear on the belt.
Plus, belt tension was good.  I am already thinking about maybe too good.  But my other car has same tension and no problems there.
It is hard to describe the sound.  I called it "squeal" but it is like "moaning squeal" (or "squealing moan").
I am about to take alternator apart again.  It is a shame when I am on the middle of A/C conversion job and time is pretty limited.
