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?
