Yes a bad bearing on any of your accessories or a tensioner pully (idler) can make the sound. Once the belt is off, you can isolate it. If it's an accessory, it will have to be replaced. The belt MAY be loose instead, meaning it needs a new idler. If it stops when slightly wet or you use belt dressing-it's loose and needs an idler. .

What causes a squeaky alternator and how can you fix the problem on a 96 Chrysler town and country?
A squeaky alternator is sometimes a sign that the fan belt or something associated with it is squeaking, not the alternator. (Possibly the belt or belt tensioner) So first I'd make sure it's actually the alternator squeaking before I proceeded. You could try some belt dressing on the belt and see if that helps or changes the squeak. If however it is the alternator, that's usually a sign the bearing's gone out and you will need to replace the alternator.
