Ford Super Duty (1999-2016) :: Power Steering And Brake Make Noise / Slight Humming
Sep 7, 2013
I recently had a close encounter with some large rocks on a bad road and broke the power steering cooler. I lost some fluid and pressure as I had no brakes and it steered like a log truck. Replaced the damaged part and added fluid. I was informed by ford technician that air in the lines would make noise but would eventually work itself out. Well the brakes work and steering is getting better but it is noisy with steering and brakes. How long should it take to get the air out? PS the fluid looks foamy now. I should also mention it was making a slight humming noise before the incident with the rock.

I have an 08 F250 supercab 5.4L that I bought this past July. The truck has 153000 miles on it now it had 150000 when I bought it. I don't drive it every day just usually on weekends and when I need the truck. The truck was really well maintained and had all the work done at a local ford garage. I live in western pa and lately it has been pretty cold and snowy so I have been using the 4x4 more than I normally would the past few days. My wife was driving the truck the day before yesterday and had it in 4x4.
The past 2 nights it has been really cold right around 0 degrees. I drove the truck yesterday and it just didn't seem right when I first drove it almost like there was a tire going flat or a flat spot with one of the tires. I got out and checked and everything seemed ok but it was still doing that. I saw that the passenger side hub was still locked while the drivers side was on auto and I was in 2 wheel drive. When I got home I sprayed the hubs down with PB Blaster and tapped on them with a rubber mallet. I put the truck back in 4x4 and drove it down my road to the end then put it back in 2 wheel drive and reversed down the road. When I got back into my driveway and checked the hubs were both in auto so all was good. T
he only thing now is when I am driving everything is normal but when I start to brake or decelerate I get a humming noise like you would get with off road tires on the highway. I wouldn't say that it is that loud but definitely noticeable and there is a vibration in the floor in the front along with the humming. When I am going really slow decelerating you can also hear a noise similar to if you would spin one of those wheels with the metal pegs at a carnival or something to win a prize.

I have a 2011 F250 4x4 with 8000 miles. I put a 3.5" ReadyLift on it at 3500miles and Rancho dual stabilizers at 5000miles. This past week I've started to noticed my truck's steering making slight popping noises when turning the steering wheel. I crawled under the truck today and I can't pin point the orgin of the noise. It seems it is coming from higher up in the steering system possibly. It doesn't seem to be from the wheels or tie rod.

2000 crew cab powerstroke 4x4... It's a XLT, six inch lift, weld wheels, BFG all terrain (50%). 277,000. One owner. Clean Carfax. All service done by purchase dealer. Mostly stock other than that. Dealer just replaced AC compressor and charged system. Interior is good, except for driver's edge seat. Good cleaning and ok.
The (my?) Truck.Downside. Power door locks make noise but don't work, remote mirror switch intermittent, stereo broken. During my test drive (alone) it drove straight, stopped straight and hard. 4x4 engaged and worked well. No noise in system. Good acceleration. No rattles or noises. Doesn't drip anything on the ground. Cruise and all accessories work.
I'm supposed to go in Monday. My girl is afraid of the mileage. But it seems well maintained for 17 years old. Is 10k an acceptable price? They wanted 11,900. Anything I should be looking for?

Have a problem When i make a slight turn to the left sounds like the tire is rubbing the inner fender. Don't do it all the time. The tire is not rubbing.

I have a 2009 f250 4x4 . When i make a turn and sometimes while driving the steering locks up. Sometimes i have to jerk it back. Sometimes it feels like i have no power steering . And some times its seems the gear box is stripped. I had it to a mechanic look at it and all the steering and suspension parts are good. The u joints are also good. There has to be a HUGE problem with this issue, due to know one having a steering box, even the dealer. I have a truck that I can't drive...

I have power steering fluid leaking out of the bottom of the Brake master cylinder out of a round hole. Every time I pushed brakes it leaks a good amount of power steering fluid out. Why it would do this and is there a screw missing out of the hole or what?

I've had a large leak from somewhere in my power steering/brake boost system (the whole reservoir gone in under a week) and I want to finally get to the bottom of it. Instead of paying a mechanic labor, I figured I'll look at it myself. So I got under it and I think that the leak is coming from the power steering gearbox, or a line that goes to it, but how to figure out which. How to diagnose this HydroBoost leak on my 6.4L? Here are some pictures ....

i have a 2006 F250 XLT 5.4L 4x4 Crew Cab. after months of dealing with an ongoing power steering issue and replacing pumps left and right, i decided to replace the entire power steering system. Ordered Gearbox, Pump and Cooler from dealership. The install went fairly easy, and finished in 2 days.
The truck used to whine and grind as i would turn wheel any direction, driving or in park and the wheel used to pull , like jerk a bit when i would go like in a u-turn.
Not anymore, all those issues are gone. Steers straight , no whining , wheel doesn't pull anymore and all seems fine, EXCEPT when i take a turn , for example onto a driveway where its a bit of an incline. Then, i hear some grinding noise and a bit of vibration in my wheel. I think it comes from gearbox or pump.
Im scared not to drive it too much as all is new components and don't want to ruin all over again.

I've noticed lately when I turn the steering wheel slowly I get a slight creaking sound from somewhere behind the wheel. What is causing it and if it's worth tearing it apart to fix it. I only notice the noise when the radio is off and turning the wheel while sitting still.

I'm working on an 05 with a 5.4. I got it with a bad valvetrain noise on the PS, which ended up being a bad cam, and one bad rocker. I changed the bad rocker and any others that showed any wear, the cam, and all 12 lifters on that head.
The truck starts, idles, runs, and drives fine; identical to my own 05. But if I get on it, it has a dead spot around 3-4k rpm, then picks right up again. After a while, I get the p0012 (Variable camshaft timing over-retarded bank 1). After I get it pissed off, the idle gets rough as well and bogs down.
Now I know the cam went it correctly. I used the wedge tool so the phaser never left the timing chain. I marked the chain as well just to be safe, and the phaser only goes on the cam in one position. Also, it idles too nicely, and runs fine under normal acceleration.
Tonight I swapped the VCT solenoids from one side to the other. It took a lot longer to get the code, but finally came up as a freeze frame dtc, and on Bank 1 again, so it's not the solenoid.
So in my mind, all I can think is that the timing chain jumped (which I don't think is likely due to the good running under normal conditions), or the phaser is bad/sticking on Bank 1. I popped off the oil fill tube and the phaser looks fine physically, so I don't think I banged into it somewhere along the line. I also manually excited the Bank 1 solenoid by grounding the purple wire, and it gives my the same rough idle which I get after the p0012.
It looks like the phaser to me. Another mistake I made was not scanning the truck when I first got it. It came right from a repair shop which diagnosed the camshaft, but I would have at least known if they cleared any codes from it.

Truck seems to run ok, but when I push the brake pedal down a bit, a strange grinding/howling noise comes from the engine bay and same thing with the power steering. When I put the brake pedal down to the floor, it stops?

I only hear it at low speeds, but I guess that's to be expected. I've heard a similar noise before with other cars/trucks, but I can't recall what causes it. Just looking on tips for where to start looking with the front end parts or wheel/caliper assembly.
Also, but not sure it's related, had a lot of front end wobble when I applied the brakes coming down steep hills last week while pulling a big, but empty, gooseneck trailer. I assumed warped rotors, but later, after I had picked up my load, it quit doing it, albeit I had started babying the brakes. Still, there was one instance of very hard braking and it didn't do it at all, but that was on straight pavement.
It's almost as if having that empty trailer and/or going down a steep hill caused it, and not anything on the truck. But the rubbing sound started before that wobbling. Whatcha think?

2002 5.4L... I have a humming noise that comes from my engine and wanted to see if any of yall knew anything about it. I sounds like it's on the other side on the driver side firewall near the brake booster. Once the engine runs for a bit it tends to start then. It'll start to hum then ill tap the gas to get the RPMs up a bit then its gone for couple miles then its right back on.

I just bought a 11 f350 powerstroke. CC lariat 4x4 with 70k miles. Whenever i turn off the truck abt 30-45 seconds later a humming starts and continues for abt 1 minute. Sounds like a pump or a release of air? Is this a normal function or should i have it checked out. I've searched around but found very mixed answers.

I have an '06 F-250 that's making a quiet grinding/humming noise from what sounds like the front end. It doesn't seem to be coming from any side in particular, just an omnipresent noise whenever the truck is moving. It's constant with speed, and most noticable between 30-60 KPH.
Truck has about 268,000 KM on it right now, and has been worked pretty hard for whatever that's worth as well.

I have a 2004 ford f250 5.4 and ithe makes a Humming noise only at idle. I have checked the fan clutch. it seems to be good and does not spin freely. I was thinking maybe idle air control valve but the truck idles like normal and does not stall. the sound does go away when squeezing the air hose doing today the IAC but comes back as soon as you let off. can it still be the idle air control valve if idles fine and doesn't stall?

Every time I apply brakes I hear a weird humming noise, as well as no stopping power. Checked fluids and pads and everything is where it should be. I heard abs can cause this but not sure on that. I know my master cylinder has a very small leak but it hasn't lost any fluids of that sort. I'm lost. I don't know where else to look.

I've been noticing a low pitched humming noise coming from what sounds like the passenger side of the engine. it happened only occasionally at first but within a week of first hearing it, it is now almost all the time. here is some specifics...
-the noise always starts about 2 or 3 seconds after starting the engine.
-the pitch or loudness does not change with increased rpms or with truck in gear driving.
-the noise randomly stops for no given reason whether driving or idling then starts back up again.
-there are no performance issues while making noise, no dip in rpms, nothing. still runs the same
I've listened with the hood up and cant identify where the noise is coming from. is this something i need to get fixed asap or no? I've got a 2001 f250 5.4 with a manual tranny ....

I would like to know what's happening, it seems as if idling for a minute to let my transmission temperature dial raise past the lowest line on the dial fixes or at least drastically reduces a couple issues.
The truck will deliver power much smoother off the line. I've been concerned about this for a while. The degree to which it happened wasn't constant but it seems like the truck is having trouble grabbing on (so to say) to the power coming off the line. I sort of liken it to a rope. When I give it the beans the rope goes forward but it takes a half a second or so for the truck to "grab" on to the rope. Never hard shifts, it's just delivering the power off the line or from a near stop.
Idling for a minute seems to fix this, power delivery is smooth off the line. Transmission dipstick was nice and pink but smelled slightly burnt. This is with the engine cold overnight. Didn't have time to do multiple wipes or check in the handbook for the proper methods of checking fluid, I just pulled it out quickly to take a look before heading out. Fluid covered the whole tip.
Second issue that seems to be fixed is that the battery light doesn't come on nearly as much and not for nearly as long. Typically the battery light will come on and off seemingly on its own whim during the drive. However, it seems to stay more consistently off if I idle right after startup.
Now bear in mind I baby my truck, I don't rev it high right after startup. Just low enough to cruise around the parking lot until I hit the road then I accelerate up to 40 - 60 depending on my route. I'd gladly give it the minute to warm up in the future but if I could get down to the bottom of this that'd be preferred, I doubt this is required behavior.
I do realize that these issues are not tied to startup behavior but I find it interesting that idling for a minute at startup to let the transmission gauge rise seems to mitigate these symptoms.
