Was riding with the windows down a few months ago and heard a whining sound coming from the power steering pump, topped it off and it went away. Noticed a bit of fluid on the "high pressure power steering line" to the right of the pump if you're looking down on the motor. The pump will run low at the end of the week but it never whines.
Fast forward to today and we have an actively leaking line somewhere causing the pump to dry out every night!
Anyone familiar with this issue? Don't want to go spending the money to replace the pump and all of the lines if it's not needed! any help is always welcome
** also, is there a specific procedure for changing that pressure line?
Driver/front wheel well, moisture on the frame is from the leak
The hose is not hard to change out. You will likely need to pull the CAC pipe to do the job and I would recommend doing so anyway. Just be sure to torque the pipe bands to spec on instillation.
Top the reservoir off and keep an eye on it for a bit. You will likely have a good bit of air in the system.
Remember to use the recommended fluid... Mercon V ATF.
Might even be a good time to do a full system fluid exchange.
If the high pressure fitting at the pump is leaking it likely has a failed o-ring or the Teflon gasket. If you decide to replace the HP hose then use a Ford hose as the pump fitting is a much better design than the aftermarket box store hoses. With the two fittings side by side it’s obvious the difference. Also, when torquing the white teflon fitting in the pump, just “snug it up”, over torquing may cause the gasket to fail prematurely.

Looking at these two pictures says to me that you are being given an advance warning of imminent high pressure hose failure. Something I didn't notice until it gave up two days drive away from home. Fortunately it was an easy fix, but I was sweating bullets until it was repaired due to the rather rural location that the RV park was located in. Last I checked, the pump to brake booster hose was in the neighborhood of $35.00 at the local NAPA store and it was a high quality hose, too.
Mine blew on the way home.... when I got to house about one mile away.... uh??? Not leaking ?? Got the wife out to turn steering wheel while I looked for leak. Touched the high pressure hose with my finger and it blew out into my face. Take my word for it.... it can get HOT !!
Yup, mine blew back in Feb. New hose from store, 2 jacks to lift truck up and start turning wheel and pumping brake. Make sure to remove the return line(factory clamp) and run a clear hose from it to a bucket, to purge the system..took me 5 wyd to do the flush/refill
Guys, I had several HP hose failures on my ‘02 F250 and always away from home since my truck was used primarily for travel at work, so I replaced the main hose with a SS flex (teflon lined) hose from the hydraulic shop with the fittings shown in the photos. This was done several years ago and is still working fine with no leaks/failures.
Comparison of Frord HP hose fittings. From pump to hydro boost. I used the 90 def fitting, better clearance.
