Need a favor from those with SBM and power steering.

Got my replacement viscous fan clutch today and installed it. Guess what???? Not the issue. Ugh!!!
I removed it again and ran without the fan and clutch. No screech. Gotta be the extra weight hanging off the end of the
water pump making bearing noise or as Mopar73340 said impeller rubbing but I would think that would happened at any
RPM. Any other thoughts? I would really hate to replace the water pump without that being the issue.
