I really noticed it one time when I was making a turn around in a cul-de-sac, and I was moving forward in 2nd gear with only a bit of gas, so my rev's dropped of course like usual but this is the first time its happened to me that my PS pump started to make a clicking sound. Is it the PS pump not getting enough power when making a corner like that at lower RPM's? It never did that before until recently. There is plenty of fluid in the reservoir.

Ive never heard a PS pump click before. Id guess u-joint. Is the noise repeatable? Try to duplicate the noise with the front end jacked off the ground.

I'd say hubs, wheel bearings

my 90 does it and both hubs are shot.
Do the hubs need to be locked to hear it? Because I thought I noticed one of my hubs didn't click into the lock position the other day when I had them locked (I did some light wheeling).

I never drive around with them engaged though.

I suppose you could get some clicking from a p/s pump, but I would think it'd be pretty fast (short time between clicks). The little "flippers" inside attached to the rotor could be damaged and doing that but...man that'd be weird. Usually you have to run these pumps dry for a long time for that kind of damage. I'd try replicating the noise, but next time, stop the vehicle and make sure it's not being caused by the drivetrain, suspension, or wheels/hubs/bearings.

I know for sure I only hear it while turning sharply, especially at a lower speed. I'm just saying I really noticed it when making a sharper turn in 2nd gear when the RPM's had dropped. But I've done this before as I never usually go back into 1st unless I'm starting from a stand still.

I dunno if this is related, but my right radius arm bushing is practically all gone, and its been causing my radius arm to move a bit and squeek on turns, and in result of it being able to move, the shock that mounts on top of it is coming loose and basically doing nothing. I have no choice but to drive the truck for now but it is going back to the shop for it probably on Wednesday. Could something with that cause it?

Maybe you could try coasting in a circle with your engine off to see if your pump is the source of the noise.

I know exactly what you are talking about, Mine dose it too,:chili: but only when wheeling. Usually when a rock or something is forcing my wheels to turn while I am trying to go straight. The first time I heard it I thought it was the trans because the clicking was in time with the rpm's. I figured it was time to upgrade the steering.
Also, Check your steering stops.

You think my stops are adjusted too far?

Just an update - It only does it on sharp left turns, but does not have to be held to the stop to hear it. It seems to be coming from something other than the PS pump though, almost sounds like my tire is rubbing against something but I don't see what it would be rubbing against. Sounds kinda like a baseball card in spokes now that I've paid more attention to it. Could this be related to my right radius arm being loose and missing quite a bit of its bushing (loose because of the bushing being gone)?

Never ends...

:banghead

Well, mechanic found the problem. Apparently my core support is rotted out so bad (I knew it was getting pretty rusty) that when I make a turn, especially left turns, the bushings underneath there are also rotted out so that when I turn, the body sags and causes the fan shroud to hit the fan. So now I'll have to be visiting a body shop to see what they can do about that.

After having the RA bushing replaced I also need an alignment, that was expected as well, so I'm waiting for Farm and Fleet to get an opening and then take it in there. Right now I'm sportin' this a little bit. \--o-/

He also looked at my shocks, they're shot as well. The Rancho shocks didn't last as long as I thought they would.

Interesting diagnosis, that it fits the bill and they are known to rot. The core support can be fixed pretty easily, there are writeups on FSB.
Side note: What does the raduis arm bushing have to do with your camber \--o-/?
