Well, since we are on the subject of power steering......

My pump has been squealing like a stuck pig every morning the last few days since it got cold. First time it happened i stopped and checked the fluid level to find that it was nice and frothy which led me to believe that maybe it had some moisture in it. After a minute of warming up, it quieted down and away I went.
That afternoon I suctioned out as much old fluid as I could and replaced it w/ fresh fluid. The next morning was the same noisy pump but a little better than before. Here we are a couple days later and it is still doing it but only in the morning when real cold (night temps into the 30-40's) but it is fine in the afternoon when temps are in the 50's.

Anyhow, Anyone else experience similar PS pump squealing and what was Your fix?

(fwiw, I'll be completely changing out all the fluid for Amsoil Syn power steering fluid this weekend, hoping that will fix the problem...Oh and this IS on my SFA fwtiw so it is factory pump but running the Ford recirculating ball steering box)

You might have to siphon it out two or three times to get all the bad old fluid out.

Fill it with regular fluid, run it and turn the wheel back/forth to run the fluid through the lines.
Siphon again to get more of the old stuff out.

When you siphon the pump, there's still a lot of bad old fluid in the lines that needs to come out too...a couple of siphonings ought to get most of it.

I'm starting to think that power steering fluid should be replaced yearly (or nearly) in these KJs.

thats same stuff was happening to me and it turns out i have a very slow leak in the power steering pump and on on of the lines going into the pump. its all covered under extended warrantee

Mine does the same thing now that it has became cold. Should have heard it today and yesterday when it was -17(without windchill). Every Dodge-Chrysler-Jeep vehicle I have owned has done it in the cold winter. My last Ram Cummins I sucked some of the fluid out and put in some Lucas Power Steering Treatment. That made a huge difference but I would say if the Amsoil power steering resists thickening in the extreme cold that should work also.

thinking about just changing out the pump then flushing it all. anyone have a good, cheap dealer or online to order hard parts from?
I was just quoted $96.25 for the tensioner and $195 for the pump (in case I decide to just replace it) oh, and $53.35 for the belt....was told that the new tensioner "requires" That belt..."mumble..mumble..think it is a different length due to changes to the tensioner" he said....?!?! Anyone else hear that?

I think the Jeep is just taking after its owner and whining... 30-40 at night is cold.... We didn't even get to 13 yesterday as a high! Subaru didn't squeel... almost didn't start, but didn't whine....

Seriously though, it may be air or moisture as you guessed. I think if you purge the system you may be fine.

If you can read this you don't need glasses, go Wheel your Jeep!

Dry bleeding the system out first, while your at it add a filter.

PS pumps with plastic tanks are known to be squealers in the cold,not that all do it but they are more prone due to the fact the plastic tanks are sealed to the pump with a o-ring.Since plastic doesn't expand/contract as much as aluminum or steel that seal area is prone to warping a little at certian times and allowing air into the system causing noise.
