Holy hell does that noise sound familiar. My van makes those same exact noises and I also have not pinpointed them as of yet. I am leaning towards it being the belt and the tensioner. It is eerie how similar your noise is to mine. If I find a fix I will be sure to post back here.

I am going to say alternator too. However, b4 you jump the gun, I would remove the belt and hand spin every pulley first.

Did this fix the problem?... (cant tell if this was a plan or if this was what he did)
my 2006 is making this exact sound too. I see 2 different solutions in the replys... could it either be the tensioner pulley OR the alternator?
... did talk to a car knowledgeable friend who had a Chevy S-10 with the exact same sound, and his was the tensioner pulley

I case anyone pops this up... still have the sound but did alot of online research.
One video I found on youtube (don't have the link)...pretty much sealed the deal that it is a very common problem with Caravans from 01 to 07.... it is the pulley on the alternator.
The pulley is what the call an ADP or decoupler pulley...acts like a clutch type pulley... and is notorious for going bad and making this sound..
it can be replaced independent of the whole alternator, but you still have to take the alternator out of the vehicle to replace it, and it 'says' it requires a special tool to get it off.
Checked the local auto parts store, and they can get one for around $70, but they dont have the tool to loan out.... found the pulley on Rock Auto site for around $45
