Ok lets me start off by saying Yes ive used the search button. Ive read MOST of the threads containing others power steering problems.

Was on leave for 2 weeks, 1 week into driving the truck i started to hear the powersteering pump making noise. Checked fluid lvl and condition of the fluid. All looked good, read a few threads stating that if you flush the system with new tranny fluid it'll go back to the way it was. Tried that didnt work so i figured the larger tires had taken its toll on it so i bought a reman at napa. Installed it, flushed the old(new) fluid out again and replaced with fresh tranny fluid. This pump made ALOT of noise, thinking there was air it in i flushed it again, but still made same noise. Also read that if you crook the wheel to the left when parked and let it sit over night and vis-versa in a couple days it will quite down...nope. Then started noticing it leaking from somewhere. Checked the hoses, hoses were good, somewhere behind the IC pipe it was coming out but couldnt find it for the life of me. Wouldnt leak sitting there(turning wheel side to side, and pushing on the brake) would only leak after a good drive. The fitting on the side of the pump wasnt wet at all so i know the seal is good in there. Also checked the dipstick/cap and the seal is nice and tight there. Checked the other two hoses going to the pump and replaced those crappy ford hose clamps with REAL hose clamps and there on there nice and tight. But still leaked....from somewhere.

So I figured maybe...just maybe i got a bad remaned pump from napa. Took it back got another one and installed, again flushed with new fluid. This one WASNT so loud but could still be heard, and I thought ok..i did get a bad remaned pump. Since the noise was still there, i flushed yet again, tried the crookin the wheel thing but still the noise is there. Even when i press on the pedal lightly it can be heard. Also before i changed pump(original pump)when I would hit the brakes the pedal would feel like it hit a soft wall...could still push it past that wall but needed a hole lota convincing. But now my pedal is "soft" and no more "wall". Since this one was quiter I figured it just needed to be broke in, so i took the 1110 mile trip down to TX without it leaking a drop. Now ive been here for a good 3 weeks and it now just starting to leak again, not any puddles yet but can see fluid forming a drip on the bottom of the pump. Hoses are still tight, fluid is still good. Will have to tear the IC pipe outa there 2morrow to confirm anything.

Ive throw two pumps and ahole lota fluid at it and still got leaking and noise, not to mention performance issues with it(idling, not moving she dosnt wanna turn the wheels)


Sorry for the long read~I welcome ANY suggestions as to what some have done to fix theirs 1st hand. Thanks and sorry for the long read~

I dont got very many tools and Ill have to buy another pully puller to change it out if i have to again. I know where advanced auto and napa are around Killeen TX but thats it~

 

You mention a little about the brakes, but not enough...

What kinda shape are they in, not pads, rotors and calipers. But master cylinderish, what kinda shape is your slave cylinder in... all these are connected.

 

How do i go about checking the master cylinder? Shes got fluid, looks and smells like brake fluid.

 

Just went out and checked with a flashlight. There are no leaks, nor any sights of outer physical damage or worn spots on it.

The best way i can describe it is, i can "feel" the power steering pump noise in the pedal when I push on it...if that makes any sense.

 

Did you use synthetic fluid? I (think) have read here that others have quiteted(sic) the PS pump down by using synthetic.

At least this will bump you back to the top.

 

I wonder if the hydroboost unit has failed internally and the pump has to work extra hard to make up for it. Hence the noise and the wierd pedal behavior.

 

Dan that sounds possible.....does anyone know how to check/test the hydroboost portion of the system?

I did not use synthetic....i will try that next.

And this is for testing the power steering.
