There is no slop in any of the pulleys. they all spin freely but the engine pulley.
the alternator makes a very slight squeak, but spins freely other wise.
The water pump pulley made a slight scraping noise that sounded like it was from where the pulley contact the pump. I cleaned that off and gave it a squirt of oil. (NOT IN THE HOLE) and the scraping sound went away. It turns a revolution of two when I spin it.
