This thread is mainly for the new guy that wants to do this but thinks they need two people to do this job. I did this job by myself and yes it would of been nicer to have a second person but it's doable by yourself, doing it by yourself you just get more of a work-out.

All you need to do is turn (Tires off the ground) the steering wheel a little (three little turns) while pumping the brake and watch the tubing you have running to a gallon jug. It pretty much went like this for me, turn the wheel/pump the brake get out refill the pump, then repeat. I could have stopped at 2 1/2 Qts but I went ahead and ran 3 1/2 Qts through just to make sure I had all the old stuff out

I followed this write-up
Ford Super Duty Power Steering Flush | Superdutypsd.com

I also used Mobile 1 synthetic ATF, and after doing the fluid change my pump has quieted down but it was pretty warm here today, I'll see if it really worked once the temp drops.

Thanks for the procedure. My power steering is making the whining sound and I will do this procedure.

If I recall correctly it's a 4 quart system, I may be wrong. Don't use power steering fluid!! Mercron V ATF, the same stuff the transmission takes.

 

i flushed til the fluid was bright red
