    It would be best to remove serpentine belt again and inspect/ rotate all pulleys for a possible bad bearing. Any rough pulley as it spins and excessive play would indicate a bad bearing.

    I've had the exact same problem, come to find out that my compressor is going out- the bearings that rotate are going out- it cost me about 900 dollars to fix, I had the belt changed to save time and money.
