Ford - F250 :: 1990 - Whistling Sound From The Rear When Cold
Feb 18, 2011
I have a 1990 F250 4x4. Whenever its below freezing outside, I get this whistling sound coming from the rear of the truck at very low speeds, like when I'm slowing down to stop at a light, or when I'm turning a corner. Pressing either the break or gas pedal seems to make no immediate difference in the sound. I took it to my mechanic, but it wasn't cold enough that day for him to hear it. But he did say that it is probably just that the rear differential needs servicing. Okay, so I drained and replaced the differential oil and gasket myself the next weekend. Next cold day came around and the whistling is still there.

I've noticed during the winter my 2012 6.2L engine seems to 'whistle' when it is cold. It also seems to do it intermittently...that is, it always whistles when cold, but it might stop for 30 seconds and then do it again. It does it at idle, and also when driving, just until it warms up.
What is it, and do other people's trucks here do that? I was thinking maybe the engine fan, but why would it cycle on and off for maybe 30 seconds. My other thought was A/C pump.

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.

I am having an issue with my 2002 GTI 1.8T. I have tried searching for an answer to this, and found a couple things saying maybe it could be the secondary air pump but wanted to get more opinions before I go shell out money to chase this problem.
When I start up the car in the morning after having it sit overnight, the car does the normal thing where it increases rpm's to about 1100 to warm it up. During this a loud "whistling" noise can be heard. Once the car is warmed up a little bit, the rpm's decline to about 900, and the whistling sound goes away. When this happens though it almost sounds as if a valve or something is closing causing the noise to go away.
Also, I am unsure if this is related to this, sometimes when I am driving, I will be accelerating and the car seems to stop accelerating as strong as it was, boost goes down from around 8 or 9 psi to about 4 and I seem to lose power as if I had let off the gas some. When I put my foot further down the car accelerates harder again and boost goes back up.
I have already changed spark plugs, cleaned MAF sensor, and run the 3m 3 part engine cleaning kit through it.

It is as an electronic whistle/humming. The sound is coming from the rear of the van, and no, not when it's moving, even though it still does it when moving. The only thing I can think of would be the fuel pump. Because It's loudest just before the rear tires, not after them. My fiancee has heard it twice now, when she first heard it, I didn't, but this last time when I heard it, I also noticed that the gas gauge was reading just below 1/8 of a tank.
Would like to know if it's the fuel pump or something else I'm no thinking of. And if it means I have to replace the pump.

I have a tan 4-door 2006 Jeep Commander with a little over 100,000 miles. I recently had some work done to the rear end transmission. When I had hit the gas when going at high speeds, there was a loud vibrating noise coming from the bottom and rear of the vehicle, and when going downhill there was a loud whistling type of sound. Initially, my mechanic, who I've been going to for the last 8 years, looked at the vehicle and gave me a worst case scenario that the whole rear end might have to be replaced. He said it could cost a grand or more. The whole rear end did not have to be replaced. My mechanic did work on the car and fixed I don't know what on the rear end.
Before my mechanic gave me the car back he said there would be a slight whistling type sound when driving. And there is a whistling type sound, every time I hit the gas going about 20mph or more. Although my vehicle does drive and sound substantially better, this sound is driving me crazy when I'm driving. My mechanic said that there is nothing that can be done without replacing the whole rear end. Is this true? Can anything else be done to minimize or eliminate this whistling type sound?

My awesome 1990 Toyota Pickup (6 cyl., supercab), fondly named Ol' Rusty, has a measly 245,000 miles on it and still running strong. The one problem is that when it is very cold out such as this morning (-10F), I get a terrible noise coming from under the hood just in front of the steering column. It sounds like a belt rubbing, but I can't find it. It happens when I start going faster than 20 mph and goes away once the engine is completely warm. When it's happening, the speedometer jumps a bit. Interestingly, if I warm the truck up for 10 minutes or more so that the engine is completely warm, it still happens when I first drive the truck. Is this something I need to worry about or can I continue to ignore it like I have been for the last 3 years?

Early 90's Toyota Corolla.
I've been hearing this sound the past couple weeks coming from the rear of the car. Not related to the rpm, only occurs if the car is moving slowly -- like when I'm driving in a parking lot, looking for a space. Occurs when turning, even slightly, but not when going dead-straight. It it intermittant, seems to occur more often on hot afternoons, never heard it all winter, or even now in the morning. Not that loud, but noticeable. Sounds a little bit like a vibration, sort of a buzzing sound, but more musical than a simple buzz.
The best way I can describe it is that it sounds almost exactly like that sound they make in kids cartoon shows on Saturday morning, when something bad happens, like one of the characters get hit on the head with a baseball bat ..." waah waah waah" .. sort of like a muted trumpet or muted trombone.
Rear wheel bearings? Brakes?

Just bought my first Ford. Its a 2015 F250 Platinum. Im at 1400 miles and Im becoming concerned because when I start the truck for the first time in the day, no matter how long I let it sit and warm up I am noticing that on the first couple of miles of driving I hear a high revving sound as I accelerate and it seems to quick shift during those first few miles.
As I continue to drive the high rev sound just fades away and all engine sounds and shifting are as normal as can be and will remain that way until the truck has been sitting for an extended period of time and is cold. I thought it had something to do with tranny temp but this morning I let the tranny warm up to about 115 deg in neutral before taking off but still had the high rev for the first few miles. I have never owned a ford nor have I ever owned a heavy duty truck, hoping this is normal.

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.

I have a 2010 F250 extend cab 4x4. While traveling about 70 down the freeway I get a whistling noise. It is usually worse when the wind is blowing hard or behind a semi. Wind makes the noise louder so I assume the noise is coming from the air hitting something. Slow down to 50 and noise goes away. Do not think it is mechanical because when a gust hits the truck it is worse. Checked all the windows, windshield and rubber parts. Where I should look.

I have recently noticed that there is a loud, high-pitched whistling sound coming from under my hood that has progressively gotten worse over the weeks. At first, it would only occur when I had my AC or heat on and would stop immediately once i turned the AC/heat off, and will also happen from time to time when I accelerate. Now, this noise is happening right when I start my car and takes a few seconds to stop.

So heres the story..........'02 Escape, 179K miles, just had the oil changed 2 weeks ago, ever since then I've smelled oil burning when the car starts up and every now and then after exiting the car. Also have had the check engine light on intermittently for the EGR insufficient flow for the past few months. It comes and goes whenever it wants. Today Wifey called me and said something was wrong with the car, I drove it home (about 26 miles). The car runs fine as shifts through the gears, but as soon as it gets a load put on it, it cant pull hard like it used to and it gets a high pitched/squealy whistle similar to a turbo that's spooled up.
Its hard to say where its coming from but from what I can tell I'd say somewhere under the hood near the glove box. (that's the only way I can think of to describe it). There's a big long hill right outside her work that I wasn't sure I was gonna make it up. Car just didn't have any power and couldn't decide what gear to be in as RPMs were too high in a lower gear but wouldn't pull in the higher gear. Car pulls hard off the bottom but falls flat in the midrange. I was thinking maybe clogged cat but what would the whistling sound be?

Automatic transmissions! I have a 90 F250 4x 7.5 and E4OD. I have been chasing electrical gremlins, and I'm not sure if these problems are related or not. Symptoms: When starting off in drive, it feels very sluggish, as if it is starting in second gear. Manually putting in first works. When left in drive it will drop all the way into fourth at 20-25 mph. If left in drive, when you turn a corner and step into the throttle the trans will rapidly shift up and down causing a surging effect. Manually moving the shift down into second stops this. I have been considering swapping the PCM from an 89 7.5 E4OD parts truck I have, to see if that cures any of the problems.

My 1990 F-250 with the 460 overheats when driving in overdrive. Driving a hundred miles will turn the trans fluid brown and the transmission is very hot even though it drives just fine. If I drive it out of overdrive I have no problems at all.
It all works fine except the overheating in overdrive, no flashing on the overdrive light. The tans shop is not getting a code, they tell me they have to rebuild the tranny.

My 1990 4.0 refuses to start when the air temperature outside is at approx 40 degrees or below. It will crank until the battery runs dead if I let it. At approx 50 degrees farenheit the truck takes forever to start and always backfires out of the tailpipe and intake manifold (blowing off a hose on the vacuum tree) before it starts. If I can get it to backfire, it will start eventually. If it does not backfire, then I can run the battery dead and the truck still refuses to start. This condition has grown from a little problem to a huge problem over the past 6 months. Here is what I have done so far, including regular maintenance items.......
KOEO test checked OK
KOER test returned code 77 multiple times (TPS).
Replaced Throttle pos. sensor
Replace Idle air bypass valve
Subsequent KOER test came back with no more codes except 11 - OK
Load tested battery
Made new heavy gauge battery cables for + and -
New plugs, wires
newer starter
Changed coil pack for known good one off my explorer
Visually inspected hoses for vacuum leaks, replaced 1 cracked hose

Just became the proud owner of a used 2011 F-250 Supercab, 6.2L. Overall the truck is great but it does have a-few things that need fixing, the most annoying of which is a knocking sound from the rear passenger side cab corner. Sounds like the exhaust vibrating and smacking up against the floorboard but that's not it. Everything seems tight, even the front suspension.
The only thing I can see that may be the cause is the rear passenger cab mount seems worn. I can rotate the bottom rubber portion without too much effort and when I feel for the top rubber portion all I feel is the metal cup on the top, like the rubber has collapsed and the metal cup is sitting directly on the frame mount.
So... how many cab mounts there are for the Supercab? I think there are two on each side and two in the front. All of the information & videos I've seen describe the locations for the crew cab. Also, is it possible to replace the cab mounts and not have to mess with the ones in the front? I hear those are the real buggers.

My Ranger has 296,000 miles on it. Most everything has been replaced except the u-joints. It's a 2wd 2.5L with an automatic. The motor was replaced at 228,000 with a used motor with 52,000 miles. The transmission has about 60,000 miles on it. All the bearings in the rear end were replaced about 20,000 miles ago. It has the most annoying whistling noise coming from the rear only sometimes. I don't know if it's the brakes being misadjusted or a bearing with a burr in it. It happens at random times but it's such a high pitched whistling you know everyone on the road can hear it too. There is also a driveline vibration, very minor though when over 60. However, I've had the drums checked and even had the wheels balanced many times. My friend said the ujoint grease could be dried up, but the whistling noise only happens at random, the virbation is anytime you're at highway speeds. It's not a violent vibration just enough to tell that it's not a brand new truck anymore. What it could be?

I have a 2002 F250 with 189,000 miles. Im having some very bad issues that im trying to fix. The truck idles rough, with fluctuating RPM's. In certain speed reanges it also shakes and runs rough. If I turn the overdrive off the shaking pretty much stops, but it still accelerates pretty slowly. There is also a whistling noise from the front of the truck until the engine warms up, someone told me it sounds like a bad intake manifold? Does that sound right? What could be going on with my truck? All spark plugs and coil packs have been replaced, as well as the fuel injector rails.
