2009 bearing noise near oil filter?

My 09 Unlimited 3.8 with102k miles has started chirping like it has a bearing issue with an accessory. I used a stethoscope to try and locate. It sounds the loudest on the oil filter. The tension pulley had some play and slight noise, so I changed it. Chirp is still there. Thinking it is oil pump related. Anyone have any experience with this?

Take the belt off and run it briefly. Should tell you if its related to the accessory drive or internal.
