Power steering issue

Well my pressure line blew out of my power steering pump yesterday and I replaced it. I topped off my power steering with Mercon 5 transmission fluid and its still whining when I turn the wheel. Have I missed something or did I damage my power steering pump?

How long does it take for the transmission fluid to cycle thru the hydroboost system?

Several range-of-movement turns should help to clear the bubbles, but it's not instant. The pump is over a decade old... I replaced mine.

Replace it if it is old. Flush and fill with synth tranny fluid and you should be good to go.

Power steering 99.5 - 2003

I've been battling ps problems for years I have a 99 f350 SD replaced pumps, steering boxes, hydroboost, ball joints tie rod ends, even read how to bleed the system I've been a auto tec for 40 years and I've never seen anything like these trucks, I even removed the pressure valve in the pump and raised the pressure I can dead head it and get over 3000 psi, but it still doesn't help the steering, the tires are Yokohama Geolandar A/T G015 LT 315/75R16 Load E 10 Ply AT All Terrain and some threads say that you just have to live with it, so does anyone have a good solution to help it without replacing everything with aftermarket parts

Start a new thread instead of resurrecting a 12 year old one and you'll get a better response.
