Need a favor from those with SBM and power steering.

I tried soap previously and did not effect. Tried again today. Still Ng. Sanded the belt and pulleys with 80 grit. Actual!y did it with engine running. Shhhh...dont tell wife. Cleaned with distilled water. NG. I'm beginning to second guess myself. Could it be something else that uses the same belt? The belt drives the PS, water pump/fan and I have a 3 groove crank pulley. It is very difficult to isolate the sound with the engine running at a high rpm. Can't be the crank because that is always driven. So I removed the viscous fan assembly and ran it. NG. Maybe the water pump bearing but I would think it would be at all speeds. I shot the WP shaft at the bearing with WD40 and let it soak. Dunno if it worked it's way in there. NFG.
Maybe I will find another PS pulley since it does have some slight runout to it. Tried a reman pump last year so doubt it is the shaft but they both had lateral play (in/out). Figured it was normal Does someone have a known good pump that can check for shaft play for me?
