Alternator pulley misalignment on 4 cylinder engines may result in belt noise and/or the belt "walking" partially off the pulley. Our technicians tell us that replacement of the AC and alternator mounting bracket, alternator belt, and if necessary, installation of washers to align the alternator pulley may be necessary to correct this issue.

Alternator pulley misaligned with rest of engine, causing belt to walk and come off. Not sure how to fix other than what was suggested above.
Belt noise and slipping because of not lining up right.
