HI Woody

Inspect your belt for wear and tension it may be that easy.  As to the bearing you must remove the clutch plate to remove the pulley.  I South Florida some mechanics try to do it without removing compressor.  I really find that harder then just removing and replacing on the bench.  Good luck Let me know.
