POWER STEERING ISSUES
IM NOT SURE WHERE TO POST MY QUESTION, MAYBE THIS IS IT. I HAVE A 2007 FORD F450, AFTER GETTING IT BACK FROM A NOT SO GOOD SHOP FOR AN ENGINE REPLACEMENT, THE POWER STEERING WAS NOT WORKING RIGHT AT A STAND STILL POSITION OR EVEN WHEN ROLLING SLOW, THE WHOLE HYDRO SYSTEM SEEMS TO BE MALFUNCTIONING, INCLUDING THE BRAKES. NOW THIS IS WHAT IVE DONE SO FAR: REPLACED HYDRO BOOST PUMP, REPLACED GEAR BOX, LAST THING LEFT IS TO REPLACE POWER STEERING PUMP, BUT IT IS GENERATING PLENTY OF PRESSURE, WHATS NEXT? ANYONE PLEASE HELP, THANKS!!

Well I was going to suggest a Hydro Boost system Flush but with all that You have already done that fluid has to be New
The Hydro Boost pump is the Power steering Pump
The Only thing I can think of that would Affect BOTH BRakes and Power Steering would be a Plugged Hydroboost Cooler or a Collapsed/Plugged Hose in the system
Might be worth Taking the Fluid Return Line OFF and see if it has GOOD FLOW when the wheels are turned and brakes Pumped

This makes me think that maybe a Steel line may have got SMASHED/Pinched During the engine swap
Or Possibly hooked the Lines up wrong maybe slim chance this one
IDK Thinking outloud here
So when you Hit/Push the Brakes then try to Turn the Steering wheel (AT the SAME TIME) The Tires wont Turn/Rotate
This is Kinda what made me think about maybe the HydroBoost Lines are hooked wrong IDK
Sorrey about your troubles sounds like its been a Huge Nightmare at this So called shop
I wouldnt take it back to them but I might get it fixed and send them a Bill
If it took 3 months for engine replacement God Only knows whats messed up
Hell Iv Swapped Engines faster than that only working on days off and after work with a 50hr a week Job IIRC I had 3 weeks in the last one but think it was even little faster then that

to the OP, do u have steering wheel controls? like cruise control, or radio controls or a/c controls, or all of the above? if so, i think there is a TSB issued for funky or malfunctioning steering wheel. ford recommends to replace the steering wheel in tat case. i vaguely recall reading about tat somewhere a few months back, but then again, i could be wrong and tat TSB might only apply to king ranch trucks. my 2 cents.

jus curious. plenty of pressure? no offense. maybe when u replaced the power steering pump (hydroboost) there may have been a lotta air in the system. if too much air pressure in the lines, it may cause tat tightness...........yeah, sounds kinky. sorry...i couldnt resist......come to daddy.......ooops, my bad.

Ive checked all the lines, none are pinched, what i meant is that while holding the brake and tring to turn the wheel, there is no rotation in the resorvoir, the second the brakes are released the fluid starts rotating again, i compred the line connections to my 07 f550, and all lines seem to be routed correctly, you guys think it may be the power steering pump not generating enough pressure under load? Thats the last piece left to replace. Thank you all for all the input so far!!!

The hydro boost pump is ur power steering pump. It shares the same reservoir as ur brake pump. Tats why when I do a power steering fluid flush, u use the line there n u pump ur brakes to get the old fluid out. When changing out new parts, ur required to put new fluid back in. While doing tat, u may have gotten too much air in ur lines. Tats why u may be feeling too much pressure. Maybe tats it, or I could be wrong. Tats my theory, tats all.

there have been a few issues with supply do to debris in the ps resivior, i dont know if this will help your issue. check for damaged or kinked lines and the pump. the concern can be from either side.
I have seen a bad spool valve in a gear box cause this as well. I have had more then one bad rebuild on a gear box threw the years aswell.
