Need a favor from those with SBM and power steering.

Hey guys. I have tagged on to another thread where I am fighting a screech over 2000 RPM coming from PS/fan/crank. I am noticing some movement in the PS pump with increased RPM.
With your car running and standing at the drivers fender, is it normal to see movement at the pulley while increasing RPM? Almost like the pulley is moving towards the engine slightly.
Not sure if this is supposed to be rock solid or not.
