Ford 6.0L Power Stroke Diesel :: Power Steering Pump Making A Loud Whining Sound
May 27, 2015
My power steering pump was making a loud whining sound. No problem, changed the pump. Now after the truck is started I will have no power steering or brake assist, give the truck a little gas and you can hear the power steering pump "start". I have tried every way to get the air out, or is that not the problem. I even lifted the front of the truck off the ground with a forklift and with the truck off turned the wheel about six times stop to stop. Fluid level looks good and has since adding after the change.

So I have a 06 f350 6.0 and this started to happen yesterday. I was driving and all my temp gauges were ok says the tuner, but I noticed when I accelerated and went above 8psi the noise got significantly louder and wouldn't go above 17psi so the cause of this sound is making lose pressure somewhere.
- I check the hot side of the inner cooler pipe and boots for cracks or tears(nothing)
- I checked the cold side and the plastic seems to be in good shape except where the flex part meets the inner cooler had some little cracks in it
- I check the Intake for cracks, didn't see any.
Noise is still there and the loss of power.....so I'm at a loss!
Cold side pipe where I taped it
Hot side boot to inner cooler no tears
No cracks in hot side pipe
Hot side on turbo
Cold side of the inner cooler

So, I just had the fuel pump replaced on my '15 6.7 a month ago and it just died again. (next day edit: it didn't actually die, it showed all the same symptoms)
Same symptoms: whining sound, low fuel pressure warning, reduced power warning.
This time I'm 50 miles from home so I pulled off the road before it shut off. Interesting, I was in a hilly area and my low fuel warning came on too. We are waiting for a tow. I was considering trying to push on but don't want to get stuck in a dangerous spot on the highway. We're in a church parking lot.
So, last time this happened I was on flat road with about a half tank of fuel on a lunch break. I ran a mile after the warnings came on to feel out the issue and to see what would happen. I happened to be only about a mile away from my dealer so I drove that way. I got reduced power warning and then it cut power on me (limp mode). I made it to about 100 yards away before it cut off.
This time, I was in a hilly area at night on a windy two lane road with no shoulders in the woods. I was miles from civilization and was showing below a quarter tank of fuel. ~100 miles to EMPTY. I got the low fuel pressure warning first and then the reduced power mode before the whining noise started. I was climbing a hill on a curve at the time. I drove a quarter mile and then pulled off the road into a parking lot so I wouldn't be stuck on the shoulder. It didn't actually go into limp mode.
I let it sit a few minutes, talked it over with the wife and decided to call for a tow. After talking to the tow truck driver who said he would be an hour because he had to go find a bigger truck, I decided to see what I could do while I wait. I fired it back up and the fuel level dropped to below 1/8 and I was now showing 33 miles to EMPTY. I was parked on a hill with the back end up. I had backed the truck into a space to make it easier for the tow truck driver. I let it run a minute, checked for leaks and it seemed to run fine with no studdering or additional warning lights.
CEL was on but no new warnings. I put in my code reader and pulled the P0087. Just one code. I revved it a bit to see if there were any issues. It seemed fine so I decided to try my luck. I started driving towards home with the intention to stop at the first diesel station to fill up. Truck ran fine. After two minutes of driving gently, heart racing, my fuel level came back up and it now read 88 miles to EMPTY. I drove 11 miles to the nearest station and filled up. No issues. I shut it down. I fired it back up. Still no issues so with a full tank, I drove home the remaining 30 miles without issue.
Planning to take it in to the dealer Monday to get it checked. Could this be from an air pocked due to low fuel level and hilly terrain? Is my new pump dying already? Is there something else going on inside the tank or elsewhere?

Our 2006 Honda Odyssey had a power steering pump replaced in the spring. It makes a loud whining noise especially when turning. Our mechanic said this is normal!! It looks like air is in the line as the fluid looks foamy. Is there a special way to bleed the lines?

So I have a 2012 Elantra Limited. From what I understand the power steering is no hydraulics and is only electric assist. So I have a strange problem. I can remember in previous cars when a power steering pump was going bad it made a whining type noise that changed with engine speed. My Elantra is making the same type of noise. I'm trying to track this down. My car doesn't have any other symptoms aside from the noise. It's hard to really tell but it does appear to be coming from the belt side of the motor (passenger side).

I'm having some strange action in the turn where sometimes it "sticks" and also I sometimes get a loud whining sound for 10 seconds or so and I believe it's coming from the power steering but I could be wrong.
I know my ecoboost has an electronic power steering system but that's the extent of my knowledge on it. Does it have a pump anywhere in the system that could be making this whining noise?
124,+++ miles, no real issues, runs like a champ.

I think my pcm has gone bad. My wait to start light won't come on an when I turn my key on I can't hear my fuel pump cut on anymore. My vacuum pump is also making a loud noise.

When replacing the power steering pump on my 2006 should I go OEM on the pump or save some money and get a Napa or aftermarket remaned unit with the pulley installed? Also, whar is the fluid capacity of the power steering system?

I am having a heck of a time finding this coolant leak. It drips off the power steering pump. I replaced the upper radiator hose and the heater "y" hose that goes to the bottom of the Degas bottle. I recently replaced the lower radiator hose as well. So the truck runs normal. When the system is under pressure I do not see any leaks. But after the engine is completely cold it starts leaking a small puddle of coolant. Its appears to be coming from the power steering pump. But I am sure its something above or near it. This is on my 2005 Excursion with a 6.0. Can the water pump be going bad and leaking this direction. I would expect a water pump to leak straight down the middle of the engine. What to look for? The thermostat seal stays dry. but it has to be in that area. What is really messing with me is. When it is hot and pressured up It does not seem to leak. Only after it has been sitting for hours and cools off..........What the heck!

I have a 2003 F250 6.0l 4x4 with 230k miles. All of a sudden it seems that the fan is very very loud and there may be a very little lost of power. Also i just replaced the fan clutch not sure if that may have anything to do with it. What could it be. I need to get this fixed this week...

AC compressor makes a loud growling noise and lugs the engine briefly when engaged at idle and the truck has been sitting for weeks. After that initial grind, it works perfectly and makes no harsh noises. Can I replace the compressor bearing or should I swap out the entire compressor?

Black smoke is bad I think, especially when I push on the gas pedal, and I hear a bad whine or something that sounds like a very loud power steering pump whining.
I also have zero on the boost gauge. The truck barely pulls itself back home and black smoke is dribbling out of the exhaust pipe.

The truck now makes a whining sound for about 30-40 seconds on a cold startup from the fuel tank and def tank area . what could this be ? Its at the dealer for other issues also , the dealer said that it was my starter making the noise, I'm pretty sure the starter is attached to the motor and not located by the fuel tank....

After engine is up to temperature the engine has a buzzing/whining sound just at idle. Pick up rpms and its gone. They thought it was comeing from the oil filter and changed the filter and it disappeared for a while but its back again.
Very hard to pinpoint the sound even with a styphiscope. Going back to dealer.

Well, I last summer my fuel filter/ pump started squealing, and making vibrating noise, replaced the fuel filter changed the noise slightly, some times it would go away, sometimes the line going to the filter under the hood would vibrate, couple weeks ago truck warning light came on- "low fuel pressure warning" came on, hum... went out, came on a couple days later, then finally put me into limp mode, luckly only 1/2 mile from home... checked filter on frame/ tightness, it was tight, the pump on the filter housing was very noisey still, well, I figured 200 dollars cheaper than taking to ford....
I waited and pump arrived 3 days later, replaced it and low pressure warning still on, but pump was very quiet, and when I restarted low pressure warning and reduced power came on in driveway, hum.... I thought code was still in computer, I disconnected battery and turned headlights on to try and kill the code, started it and now the engine light came on, nothing else, and truck ran fine....hum.... went to autozone, and they pulled the code, low fuel rail pressure, p0087, guy said to drive and code should go off, truck runs fine. Drove truck a couple days and engine light went off, Truck runs great.......All is good.

I just recently bought a 2011 powerstroke f250 and while running I can hear the fuel pump humming pretty loud. Is this a possibility that it's going out? Or is this normal?

So I have just over 14k on my 2015....... I love the truck but have had a few small issues. I had a water leak coming in from the roof that would leak through the grab handle. Nothing major dealer replaced one clearance light seal and they said the windshield needs to be re sealed.
Then I had a god awful irritating squeak in the dash..... It only does it late In the day when it's been hot. The dealer said it was a loose air bag. I have had the truck back a week and it's doing it again.
Those are little issues that will get resolved...... I hate having problems with a brand new vehicle but I understand it happens and that's what warranty is for.
I also reported a bad shake to the dealer...... The truck will shake very violently and have a very loud "diesel" sound. It's very specific at when it occurs. It has only done 4 times in the past 6 weeks including today. The odd thing is the 4 times it has done it has been the same time of day in the exact same spot on the exact same road!!!!
Basically I leave my office sit in some traffic and by the time I get to the parkway it has been35 minutes or so. Only happens in 6th at 60 which is roughly 1,400rpm a slight load due to a small incline and it shakes real bad! The typical "diesel" sound you get when under a load is very pronounced almost to a knock. It will continue to do this as you slowly increase throttle until it down shifts and then goes away. I also caught it doing it and I manually shifted to 5th and it went away.
Because of the rpm at which it happens with slight load only doing it in 6th I lean to a Trans issue and more so a converter problem. It feels like converter shutter. I just don't understand the engine sound.
I gave very descriptive info to the dealer..... Several techs drove it and could not duplicate. I just picked the truck back up last Thursday and the dash squeak is back and the shake happened yesterday and again today. So I am a bit irritated to say the least.
I really hate the fact that I know there is a problem but I also understand if a tech can't duplicate it he can't diagnose it. However today I did get a video of it with my phone so they will know I'm not making this crap up!

I've got a noise that I just can't find. Have replaced a bunch of stuff trying to eliminate this sound.. steering pump, both front wheel bearings, new pads up front, both caliper brackets and pins. Did a new turbo, verified the new pump is not air bound, brakes work, no noise with wheels up, lock to lock, pumping brakes the whole time.
Sound is prominent at 1400 RPM, does go up with RPM, seems sometimes to follow a steer to the right. When I shut down, not at full temp a clunk happens, like a mechanical stop. That clunk is less noticed once up to temp and it really started after the steering pump. Sparky came over, listened with a probe, says it's not the pump, my BIL and a close friend say the same thing.
Today, when I nailed it, rpm came on hard, tires smoked and when I let off quick, truck died, like something held the belt. It just slowed and died, restarted immediately.
Shawn listened to the transmission, says he heard nothing there either but did hear something above that near the back of the motor.
IPR is spot on 21.8%, ICPV is .80-.82 and [email protected] However, it has been dropping to lower numbers recently, saw 15.4% and it often sits near 19.4%-20.4% for periods of time. Tap the throttle, right back to 21.8%.
I'm at a loss. I've tested everything I can think of. I can power brake the truck, no trans slippage, it spins the tires easily around 10lbs boost. The A/C seems low on the charge, it is freezing the dehydrator and I added some freon, 18oz can, the clutch is not frozen. Turn it off, compressor stops spinning like it's supposed to. The tensioners are not frozen or squealing, water pump is not making noise, temp is 200 on the dot. Trans is full, no burned smell. Motor oil is fresh, filters clean.
It sounds like a grinding noise and I'm about to tear the cover off the HPOP. I'm at 150k now and know it will need replaced soon, I've spent $2500 in the last 2 weeks, but before I tear it apart......

The steering on my truck has become a little heavy after making a turn and bringing the steering wheel back to center. The steering feels heavy like I had a front tire half way down. There's a lot of drag then once on center it's gone. Could it be the beginning of the end for my ball joints?
