It would be that noise. Take a look at the pulley. See if it has started to eat itself.

I wish I kept the bearing number! I bought two bearings (they are both the same on mine) then banged out the old ones with a large socket and then pressed the new ones in with a vice.

Yours are $ 15/ea at rockauto. The pulleys are constructed poorly on our Jeeps. So if you do a bearing swap, then do it with caution as these pulleys get distorted easily

The pulley is bought as a unit. They are about 70$. Take the belt off, unbolt the old pulley and bolt the new one in. Make sure you don't strip the threads.

Pulley unit $ 15 on rockauto. But two and replace the serpentine belt, if needed.
