remove the belts, and one by one, rotate the alternator, power steering pump, a/c and listen to which one might be making the noise. a bearing can be going bad.

Assuming original belts, I'd just replace them. Could have an idler going bad, but for sure a 8+ YO belt with 100K+ on it is on its last legs...

Just to satisfy curiosity, and because this diagnosis is so simple, try squirting some lube on the belt when it's doing it.
