The bearings on the pulley shaft themselves...

...in some cases they will seize up causing the pulley to lock up and shred the serpentine belt.

Rebuilt pumps are available from various sources as the bearings themselves are not readily available. This may be more of a deterrent for a DIY'er wanting to rebuild the pump since it is a smog-related component.
