i have an 04 f-150 with a 5.4 motor. about 2000 miles ago the power steering pump started to whine really loud. i sucked out the power steering fluid and started it up and the fluid that back into the tank looked like it was gritty and rusty. i replaced it out a few times and no change. i then did the pita job of replacing the power steering pump which was about a 5 hour job. it was quiet for about 5 miles and the new one started whining. every week i have been sucking out the old fluid and replacing it and it still seems to be gritty. what could i do to quiet it down? the steering works perfect btw. i am looking at selling this truck and buying an 09 or newer ford and want to quiet it down before selling it. the truck has 88,000 miles on it and i am the original owner.

 

Try draining the steering rack? It could be that the system has some contaminants in it and it is getting into the new pump.

 

After you do as Rudeman suggested, add a bottle of LUCAS POWER STEERING STOP LEAK. I don't like to support snake oils but this stuff works on quieting Ford power steering pumps.

It made a believer out of me.
