Mercon tranny fluid is the recommended fluid in there. Is that the best? Don't know but if I were to put a synthetic in there I would be sure to flush very well as it operates the boost/power for the brakes too. Keep it simple.

Put end of clear hose in suitable container.
Start engine, have helper turn steering wheel and pump brakes while you add fluid throught funnel to power steering reservior.
When fluid runs bright red shut it off and put back together.
Enjoy a quiet power steering pump!
I used two or three quarts Mobil 1 iirc

If you think you can, I would flush it and put in new fluid.

Our trucks don't use "power steering fluid". The power steering pump uses ATF. When I had an bumpup last year and busted the pump coolant line, the guy that made the quick repair to the line add about 2/3 of NAPA power steering fluid to the resevoir. It was my fault for not watching, i guess the cop had my attention. Anyway, pump sounded bad all the way home 350+ miles. Got home and called back to the station that made the repairs and he said that he did use power steering fluid and also stated that is what goes in there. I flushed the system with syn atf and it has never sounded better.
