Is there supposed to be a bit of play in the steering rack?

[GetOuttaMyWay]

I've had a shimmy in my front end for a few months. I assumed it was the bushings in the front end. I finally lifted the front end and checked it out. The bushings, while old, don't look severely worn. I noticed there seems to be a bit of movement in the steering rack (not the tie rods) if I push on the wheels and try to turn them left-right with my hands. Is it normal to have a little play in there, or is it supposed to be tight?

I should mention it's most noticeable at lower speeds.
