I have a 1988 6cy 4.2 with a serpentine belt system. The pulley on the power steering pump is going bad and is screaming loud. (I know this cause I have replaced every other pulley and know its this one for sure. A little water shot on it will stop the screaming until the water dry's). Anyway the part number for this pulley is J3238275. Apparently this pulley is no longer made and available. Does anyone know if there is a replacement part number for this pulley? The only thing I can come up with is J53010085 made by Crown. Will this pulley work? I'm no mechanic, but can I buy a new bearing for the old pulley? Is this bearing replace able? All of the auto parts stores carry the power steering pump without the pulley. Any thoughts would be appreciated. I'm going crazy trying to fix this problem! I'm sure with all of the 88 wranglers out there, someone has to have had this same problem.
