It could be the idler pulley which is easy to replace. I would recommend doing it before it fails. You could possibly shred your drive belt.
Here's my post of when I replaced my idler pulley, belt tensioner and belt. NOTE: My car is a manual, if you have an automatic, there is no shock attached to the tensioner.
