Ford Super Duty (1999-2016) :: Sudden Hissing Noise For About 2 Seconds Happens Once Every 5 Minutes Or So
Minor noise, and it might be normal. When I have my air on, I get a sudden hissing noise for about 2 seconds, and it happens once every 5 min or so, almost to the second. Not that loud. like a blow-off valve noise, almost. Sounds like it's coming from the passenger dash area. No other ill affects that I've noticed. Not to be confused with the popular wind/intake whistle that some have. Any theories? Almost sounds like a drop of water landing on a belt, and spinning dry. But it happens on dry days too, I think.

I have a 2015 ford f250 xlt crew cab, 6.2, fx4 with about 1200 miles on it. My questions are, I have noticed a hissing or whistling noise while accelerating. I took to dealer and was told it was the throttle plates not closing all the way.I was told they all do this. Normal? Very annoying noise with windows down. Another noise I have been having is the brake pedal makes a popping noise while applying pressure to brakes. Dealer said brake pedal assembly was out of alignment. They said was out of alignment 1/8". After adjustment within a few days popping started again.

Looking for some input on a recent "hissing" noise coming from eng compartment. It's only noticeable during initial acceleration, and sometimes at the beginning of gear changes. I am assuming its tubo and/or exhaust related, as I've noticed a strong exhaust odor in the cab as well. I wasn't under load when the problem started but i was under rapid acceleration. Not noticing any fluids or oils leaking. No warning lights have tripped, as of yet.

I have a 2000 F-550 w/7.3. I am having a bit of a problem with the hvac system. When I turn the selector switch to floor heat only or put it on vent or both the a/c clutch kicks on and off. Not when I put it on defrost but as I said only when it is in the other positions. I do know that the clutch will kick in and out when on the defrost position. That is fine. But why would it kick in and out when in the heat only position?

This is the first winter for my truck, and the first time I've driven a truck in the winter. I struggled to get out of my street this morning, through 15" of unplowed heavy snow. As the traction control seems to engage, and even sometimes when it doesn't, the truck literally shakes very violently. I even had to lock the rear diff to get out this morning, but that didn't seem to make the shaking any worse. What causes the shaking? Is it just my truck? I've driven Land Rovers with full-time 4x4 for years, never any shaking even when they are spinning like crazy and traction control is operating. One thing I did learn that seemed to be a question of several on this forum...traction control does operate on the front wheels when 4x4 is engaged, in addition to the rears.

I guess my AC Compressor is about to the bed. AC works good however there is a lot of rattling going on. Been driving it like that for two months plus expecting it to fail.
Just not sure how long I should let it go. If the compressor pully fails on the road I will lose my serpentine belt and the ability to put the spare on and I will be stuck for sure.

Ford Super Duty (1999-2016) :: AC Not Blowing Cold / Compressor Making Whine Noise
This week was our first nice week of the year. Monday I got in my truck at lunch time turned the a.c. on and it blew ice cold. Today my truck sat in the sun all day and I got in it and turned the a.c. on. I noticed instead of the normal "click" you hear when the clutch engages in the a.c. compressor I got a wine and wimper kind of noise. The system never cooled the air after this happened. Is the compressor shot? Is it safe to drive or is the compressor going to tear itself up and send metal pieces thru the system?

So a few months ago I would occasionally hear what appeared to be a slight squealing noise from a pulley when I started my truck. It was very intermittent, so I didn't think much of it.
After a few weeks, I realized I was only hearing it on colder mornings - it would also go away rather quickly. I bought a mechanic's stethoscope, and figured I'd get to it on a slow day.
Today, I finally broke out the scope and tried to figure out the source. Didn't really find any pulleys making noise, and I did notice that when I shut the truck off, it squeaks for a second or two as it comes to a complete stop.
My dream of finding a bad pulley or perhaps a power steering pump was crushed. I had hoped to do a little Easter wrenching and put this noise to rest. So, I did what any good mechanic would do - I Googled the issue.
I'm reading that it could be the belt. Certainly wouldn't bother me too much as that is an easy fix. The belt isn't too old - about 4 years and 20 - 30K on it.
I took a few pics of the belt and can take a video of start/stop ....
Ford Super Duty (1999-2016) :: 2011 - Slight Popping Noise When Turning Steering Wheel
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.

2002 Ford F250 4x4 Superduty Lariat (4 door). Just changed the locking hubs to a new set of Warn manuals. I began to periodically hear what sounds like a rumbling/bearingish/howling kinda sound. Happens when you hit a bump at any speed...then howls till you hit another bump..goes away..then process repeats. Come to a complete stop, and the sound usually goes away till you hit another bump. The hubs are "free" at this time.
Heres the weird thing...when the noise starts...I switch it into 4 wheel drive on the dash...the sound instantly goes away. Click it back outta 4 wheel drive (hubs are still unlocked this whole time) and the sound is gone. drive some more down the road, maybe hit a slight bump, and the sound returns. Switch it back into 4x4...sound instantly goes away. Its not really in 4 wheel drive, cause the hubs aren't locked in...but that cures it till I take it back out. What could be causing this howling ? Its getting worse, and you can feel a slight vibration in the floor now when its doing it.
Ford Super Duty (1999-2016) :: Power Steering And Brake Make Noise / Slight Humming
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 am in the process of replacing the front hub seals so my ESOF works again. I tested both front hubs with a mityvac and neither one of them holds any vacuum at all. All the lines are good, and the pump and solenoid seem to be working fine.
I have the driver's side apart and I have a couple of questions.
What's a good source for the vacuum seal? I've checked rockauto, riff raff, and diesel o-rings. Diesel o-rings has it, but the description says it's only for 2003+ Excursions so I didn't order it.
There is no yellow o-ring anywhere on the hub. I assume that someone forgot to put this o-ring back in and this is why I don't have ESOF? I guess what I really want to know is that there isn't some 2000-specific thing where there's no o-ring, right?
After I got the hub off, I spun it around on my workbench and it doesn't sound good at all. It makes a slight metallic grinding noise about 1/2 way around. I assume this isn't normal? AFAIK these are all original parts - but the missing o-ring means to me that someone already had it apart.
There was a lot of water intrusion and rusty colored grease but nothing was dry, the needle bearings were intact and the shaft isn't scored at all where the bearing rides. I'm hoping new seals and good cleaning and it should be good as new. And then it's off to the next side.
Ford Super Duty (1999-2016) :: 2012 F250 - Hissing Between Shifts When Run WOT
2012 F-250 6.2 gas 4X4 SC/SB: when I run WOT, or near that, from a slow speed, I hear a short "hiss" between the 1-2, 2-3, and i think 3-4 shifts. I can also feel that the engine eases up quite a bit during the shift, and it is kind of a slow, soft shift. It has about 2,000 miles on it. I bought it in March 2013 as a leftover (great price!). The door sticker says it was manufactured in 4/2012, so it sat on the lot for quite a while before i bought it. But i don't remember it doing this when it was newer (~500 miles).
With the lite weight of this configuration (it is an XL so it isn't even carrying around 4 speakers ha ha), and me rarely carrying a very heavy load (yet) or towing anything, I rarely have to step on it very much in normal driving... it hardly ever gets above 2,500 rpm unless I am just running it faster for fun.
The hiss and slow shift happen at any transmission temperature. Of course, it never has been above the left side of the "gear" pic on the temp gauge, where it always is after full warm-up. Well, I'm hoping it is just shifting soft like this because it has "learned" my lite-foot driving style (even when I'm in a hurry of course the engine rarely has to work very hard).
Ford Super Duty (1999-2016) :: 2000 F350 Takes Forever To Start When Cold / Water In Fuel Light Keeps Kicking In
So the first issue is, if the vehicle is cold (regardless of temp outside) it takes forever to start it. It cranks and cranks and cranks and after a couple seconds of cranking I stop, wait a second, then try again. Usually it takes two sometimes three tries to start it. The guy who I bought it off of said it has newer glow plugs (last year I believe) and also I have replaced the batteries. Once its warmed up it does not do this at all.
Secondly and also something that just recently started happening, my water in fuel light keeps kicking in. I drained the water out of the water catcher reservoir under the truck multiple times and the first time water actually came out but every time after that simply diesel fuel comes out. I added a bottle of water remover to the fuel as well and ran it down to a quarter tank. Then filled the truck up completely, added two more bottles of water remover. The light still comes on. I noticed it only comes on when I am going up or down a fill. When I am driving on flat ground it does not kick on.
Ford Super Duty (1999-2016) :: Hissing Sound From AC That Lasts For A Couple Of Seconds Then Goes Away
I used the a/c for the first time this year on my 2013 F250 and heard some noises I don't remember hearing before. When the a/c(or defrost) is on every 12 sec or so I hear a hissing sound that lasts for a couple of seconds then goes away. Is this the compressor cycling and if so is it normal to hear it inside the cab?
I know it has to do with the a/c because if I shut it off as the hissing sound is being made the sound will instantly stop. Other than the noise the a/c works fine and blows cold air. Also, if it matters I have the standard control panel, not climate control.

Have a Whistling or hissing sound while accelerating? My 2015 6.2 seems to make this sound while under load. I took to dealer and they claim its the throttle plates not closing all the way. Claims this is normal, but to me it is annoying. Just would like to know what others think.

2012 6.2 XLT 50,000 miles with manual single zone controls. I haven't had time to work on it yet, but it seems that my AC compressor is not engaging. The dash controls light up normal, fan comes on, etc. I am just looking to see if there are any common failure points. I know it COULD be low on charge, clutch could be bad, etc. I am just checking if there is a common failure with these trucks AC system.
