Squeeling noise coming from engine - 2005 Jeep Wrangler

[Jules_tj_atx]

Good morning fellow Jeepsters. My 2005 Jeep Wrangler is producing a squealing sound. I replaced the serpentine belt and the tension adjuster. This fixed the problem for a couple of days, but now the noise has returned with a vengeance.

Has anyone else experienced something similar who could shed some light on my situation?

Thank you,

Julian

Two items but first track the noise to the source. The idler pulley is common and noise will resonate from there. If it sounds like it is closer to the battery, the ODPA has issues with 04 thru 06.

Edit: darn autocorrect.

Just replaced my idler pulley. It was squealing so loud couldn't hear the radio.
