Could also be a bearing in the idler pulley or other pulleys.
I would take the belt off and grab the pulleys to see any obvious play.
You mentioned lubrication? If you are talking about belt dressing, don't waste your money, replace the belt and clean any grease/oil off all pulleys.
Also check that you have no leaks around the belt e.G. Coolant from a leaking waterpump.
