Is some play in AC/Power Steering pump normal?

My TJ is about 10 years old and has about 160k miles on it. If you pull on either of these two pumps you feel a little play, but not enough to really measure. The alter and pulleys have no play what so ever in them. So I'm guessing this is normal and the bearings are not going out or anything like that...

I'm pretty sure the play should be negligible. I'll know better tomorrow hopefully, if my power steering pump rebuild kit arrives from Rockauto. My bearing went bad and ended up pissing fluid out of the front of the pump just as I got home. I'm rebuilding as a recon pump is over 200 ($300) here. I have about 138k miles on mine.

Just rebuilt my pump over the weekend. There is no play detectable in the bearing itself, but there is a small amount of play in the way the bearing fits into the pump. It is held in place with a circlip. My old bearing was a snug fit within the housing, due to the dirt of thirteen years and 138k miles, and a bit of light corrosion.

I only realised my bearing was on the way out a few weeks ago due to the noise transmitting through the fluid to the steering box and up the steering column. Best way to tell the condition of the PS pump would be to remove the belt and see how the bearing feels when rotated. Mine was rough. Don't have AC so don't know about that one.
