I am pretty confident that it is the bearing, but it would be wise to
check the belt tension.
I always prefer an easy fix to a complex one!

I have found that when the alternator belt is loose, that it will scream horribly until the rpm gets up and the alternator is fully engaged.  Loosen and re tighten the belt tension as per the manual and see if the noise goes away.  It is also a good time to check the belts, and if there are any cracks, replace with new belts.
