Power Steering Pump Question

How much play (in and out, along the axis) should the power steering pump have? The pump in question is for my '93.

My pump, with 20,000 miles (Motorcraft rebuild) has about 1/16" play. This seems like way too much, considering there is a specification as to how to install the pulley so it is lined up with the belt.

I get a chirp from the belt until it warms up, and the steering pump seems to work fine.

It sounds different than my old ones, however. Instead of the traditional whine, there is more of a hiss, or sandpaper on wood sound (that's a bad analogy!)

Is it time to replace the pump?
