Ford Super Duty (1999-2016) :: Whining Noise From Alternator?

I have had this whining noise that I'm not sure what it is. It sounds like its comin from the alternator area. There are three symptoms that are confusing me though, 1st is I only hear this whine as the weather starts getting colder and the colder it is the louder it is. 2nd is it only happens around 1800rpms like when it's getting ready to shift to the next gear. I can get it to whine when I'm parked and bringing the rpms up. 3rd is after 10-15 minutes when the truck is warmed up - no more whine. The truck is used very little duing the summer and I had this whine all winter last year. Alternator appears to be working fine and I do plow a few driveways every storm. Money is tight so I don't want to replace the Alternator an find it wasn't the problem.

Ford Super Duty (1999-2016) :: Whining Or Vibration Noise Seems To Come From Somewhere Around The Antenna

I have a 2014 super duty extended cab truck and at times I get a vibration noise which seems to come from somewhere around the antenna. The little rubber flapper at the base seems to move and isn't tight against the metal. Is this causing the noise...

Ford Super Duty (1999-2016) :: F250 - Whining Noise When Accelerate

I purchased an 1999 F250 Super Duty truck last Sept., it ran great all winter, now when I accelerate I notice a whining type noise (that's the only way I can describe it) it only does this during acceleration not @ idle, could this be a bad water pump? However there are no leaks or puddles of anything in my driveway.

Ford Super Duty (1999-2016) :: 2011 - Whining And High Pitch Squeal Sound?

I have a 2011 F-350 Diesel. It started making a strange whining sound when I start it in the morning. Very random and only does it when it's 0- -4 c. Took it to the dealership and they said its the cooler fan clutch. Got it replaced yesterday, and this morning I started it up and the whining sound was back. It also had a weird vibrating sound. What it could be?

Ford Super Duty (1999-2016) :: Truck Makes A High Pitched Whining Noise

I noticed my truck makes a high pitched whining noise. It does it at idle and while acceleration up to 40 mph or so. The pitch of the wine increases with RPM'S. It is not the cold start whine issue I have researched on YouTube.

It is in the cold or warmth. No difference. It's always there. My 2012 6.2 did not sound like this at all. I have crawled under the truck and it appears like it is coming from the transmission.

Ford Super Duty (1999-2016) :: ESOF Not Going Into 4wd Intermittently?

ESOF not going into 4wd at all, except once in a blue moon... for a few times. All relays and fuses tested, swapped with known good units.

NO 4x4 light. so its electrical related. My hubs function like they should. when they are told to. I recently just swapped esof motor/gearbox on the TC. Worked 2x in the garage, went for a spin down the road, went into 2wd and stayed, wouldn't go back into 4hi brought it back inside, dinked around with resetting the GEM fuse. started working good. drove around and switched in and out of 4wd like 20 times no issues. next day, tried to go back into 4wd. nothing. Bring it back in the garage.

CURRENT DIAGNOSIS: Siting inside right now, If I flip the switch, I don't get anything. normally, that triggers the vacuum pump to suck hubs in. That doesn't turn on, the relays under the hood don't click. so it seems I am back up to the switch or GEM, or wires between.... Any test layout for how to test the switch in the dash? seems to be fairly simple, but I just wanted an exact view of what i need to test.

Ford Super Duty (1999-2016) :: 2000 F250 - Front Wheel Bearing / Manual Hub Whining

Well, I've been meaning to get to servicing/re-greasing the front hubs/bearings for a while but somehow it keeps getting moved down the list.

2000 F250SD 4X4 Gas Manual Hubs+Trans

I'm currently going through the many threads that turned up in my search query.

Driving slow with the windows down it seems like a low whine or squeal coming from the left front. Tone changes when working the steering wheel left and right. Haven't detected any grinding sounds. Any other techniques for isolating the problem? It's going up on jack stands tonight and I'm going to see if there is any wobble from the front wheels and I'll listen as I turn each of the front wheels. Oddly, the right front hub is hard to turn. Left front turns easy.

Viewed Rob259956's videos on servicing the hubs. Currently researching accessing the wheel bearings. It seems pretty straightforward. Truck has been off road but not mud bogged or anything like that. I'm guessing a bad bearing will be easy to identify as will a bad o-ring but any other stuff I should look closely at?

Ford Super Duty (1999-2016) :: 2003 6.0 4WD - Low Rumble Noise / Whining When At Light Throttle Load And Above 50 - 60 MPH

I have a 2003 F250 SD with 130K miles. I primarily use it to pull a race car, about 5000 lbs is all. It has all the upgrades, from studs to EGR delete. Ford replaced the automatic transmission in 2005. I'm looking at a truck newer than 2011, but thinking either a flex fuel 250 or diesel. I want it loaded and 4WD, but they seem expensive.

Anyway, I have bad front wheel bearings. I know this because of the low rumble noise and how it acts when I rock the steering. How tough are they?? I build my entire race cars, so I have a well-equipped garage and some ability to cuss, but I don't have a lot of time. A buddy wants to do it for $300 total for both sides plus parts cost.

Also, this is the bad part I really need input on. It has a whining when at light throttle load and above 50-60 MPH. This seems to come from the floorboard area behind me. Gear changes do NOT affect the pitch, but a change in throttle crowding makes it louder and weaker. It has no coast down noise at all, and the noise pitch seems to track the drive shaft speed. It is a whine much like the low gear set in an automatic trans, but it does it in any gear with or without 4WD on. The only thing that affects the level is slightly pushing the accelerator, speed, or weight I am towing.

Ford Super Duty (1999-2016) :: AC And Heater Fan Working Intermittently

I have a 07 F650 crewcab with a Cat engine. The air-condition and heater fan work intermittently no rime or reason to it, be driving down the road and it quites, then maybe a few hours later and it will start. A few days ago my wife turned on the key and the fan was working and then yesterday she turned the key on and it wasn't. When I bought it I watched them replace the fan and it worked for a few hundred mile then stopped, for the rest of the trip it was on and off. I replace the resistor and spliced on a new electrical connector, but still have the same problems....

Ford Super Duty (1999-2016) :: 2003 6.0 - Intermittently Not Cranking

I have a 2003 6.0 Auto that has an intermittent non cranking issue. Once it does crank it fires right up. Usually when it doesn't crank, I just keep trying the ignition until finally something connects and it will begin to crank and then start. Sometimes I can try it twice, other times I may sit there for 5 minutes fighting with it. My only issue is, I need to get this problem fixed before it becomes a bigger issue.

I don't think it is the ignition itself. When I am attempting to crank I can see the window switch lights and other things going off when I crank it which I though was normal when the starter is operating.

My first thought is the transmission range sensor which I am trying to locate. I looked on the transmission itself which seemed to make sense but I wasn't seeing anything familiar. Someone hinted it might be under the dash above the brake pedal but I am not seeing anything jumping out at me.

I also question the starter itself, but I hear no noise coming from it at all when the problem shows itself. No clunk or anything. Which makes me think something is causing the circuit to not function properly.

The other thought I had is a possibility in the wiring somewhere. Maybe a bad ground on one of the batteries? I have a brand new factory positive aux cable so I think I can scratch that off the list. The batteries are also charged as well, but cannot rule out the possibility that maybe one is bad since I did not install them. But I can make sure they are both charged, and the issue remains. Where I should check?

Ford Super Duty (1999-2016) :: 2011 - A/C Works Intermittently?

I have a 2011 F250 6.2 xlt 221k miles. I have an issue where my AC works sometimes and other times it doesn't work. On the occasion it will work kind of, meaning that it will blow cold for a few seconds (when the compressor clutch engages, but as soon as the clutch disengages I get warm air. My low pressure is at about 30psi and the high is about 140psi (seems low to me). When I bought the truck the a.c. didn't work at all. I pulled a vacuum and put the recommended 29oz of 134a in it. When it works its VERY cold. There doesn't seem to be any ryme or reason (temp, humidity, drive time) as to if it works or not. On occasion (not working) I have been able to turn off the a.c. for a couple minutes and when I turn it on it works.

Ford Super Duty (1999-2016) :: ABS Light Has Been Coming On Intermittently

ABS light has been coming on intermittently the last few days. Checked the resevoir for fluid level...topped up a bit. Changed the oil today and looked at the sensor connectors on the front brakes...ok... Got a new speed sensor and installed it....ABS is still on. Checked the old sensor with my meter and it is open circuit....no continuity, so I'm thinking it was the problem.. Is there something that has to be reset for the fault to clear, say with a code reader etc?

Ford Super Duty (1999-2016) :: 2002 - Start To Sputter Intermittently?

I have a 2002 F250 superduty with a 5.4 in it, every once in awhile it starts to sputter. Its usually when i'm easing on the gas, possibly around a certain rpm and completely random. Once it starts i can get on the gas a little and it stops. i've changed to fuel filter and air filter recently so i know its not that.

Ford Super Duty (1999-2016) :: 2012 - Heater Fan Work Intermittently?

This morning on my way to work in my 2012 F-250 I turned the heater on, controlling the temp from the temperature control. When the truck got up to temperature the heater fan would not come on accordingly to bring the inside of the truck up to the temperature that I had selected on the controls, so I tried operate the fan manually and it still didn't turn on. Once at work I didn't have really have time to look at anything with it, I did however shut the truck off and start it again and still nothing. Then after I got off work, driving home still nothing until I was about half way home then all of the sudden it started working again. I'd sure hate to have this happen again later this winter when the temperature gets below zero outside.

Ford Super Duty (1999-2016) :: 2002 - Misfire Intermittently - Cylinder 3 Or 4?

I have a 2002 F250 5.4 L with an intermittent Misfire. A little history on the truck in 2011 I replaced the motor with a Ford long block motor, only the block, I used my electronics, intake, etc, this was brand new from Ford. The truck has a total of over 300K miles. Recently it has developed an intermittent misfire. I have changed all the coils and plugs and the misfire is still present. The codes are showing a misfire in cylinder 3 but could be 4 too. The misfire is intermittent because this morning I changed the plugs and truck ran fine, drove to store and it started missing, turned truck off and started up and ran fine again. It has been doing this off and on for a few weeks.

Ford Super Duty (1999-2016) :: Battery Light Coming On Intermittently?

I have an 06 F350 with the 6.0 powerstroke. My battery light started coming on and will go out for a while, then come back on. Sometimes it flickers a little. I have checked/cleaned battery terminals (there was no corrosion). I have replaced the alternator. The batteries are just over a year old (10/12). I have not had any slow starting or any other symptoms other than the warning light. I am still having the same problems after replacing the alternator. I have checked with a voltage tester and it was reading 19+ when the light was off. When the warning light is on it was jumping from 12 - 15. This is an old tester so I'm not sure that it is working correctly. (not sure why I am getting the 19+). I'm going to go buy a new tester, but I was wondering if there is something else that could be causing the warning light. I know very little when it comes to electrical issues.
