MY 2000 - 996 Cab with 54K miles Should the pulley on my power steering pump spin as freely as the pulleys on my alternator and water pump? I have been trying to track down a high pitch hum/squeel at certain speeds and I checked the pulleys today. The pulley clearly doesn't spin like the others. I checked this last winter when I replaced the water pump and I don't recall any tension in the spinning of this pulley at that time.
Replacing the water pump on MY04 C4S and after removing serpentine belt the check of pulleys revealed a noise in the power steering pulley in both direction. There are no drivability issues at this time. The cold fluid level is per spec. The alternator spins freely clockwise but makes a little clicking noise counterclockwise. Are these signs of pending or existing problems which need to be addressed. All my forum reading only mentions noise while car is driven. Any comments appreciated and Ill check back while I continue on the water pump replacement. I have attached a pic for reference
