Ford - Ranger :: 2008 - Intermittent High-pitched Squeal After Warmed Up / Idling?
Apr 21, 2012
I have an '08 Ranger, automatic. For the last several months, the truck has been making an intermittent high-pitched squeal/whine, but only after it has been warmed up (10--15 minutes driving) and only while it is idling. As soon as I'm driving, the whine stops; whine will occur both in drive (but stopped) and in park. The whine will not happen every day I drove, nor will it happen at every stop. When it does squeal, the squeal will fade in and out in volume.
An interesting kicker I've found recently: it seems to be dependent on electrical draw. For example, if I'm sitting idle with the lights on, and the truck is squealing, and then I turn the lights off, it suddenly squeals less. Still squeals, but less than with the lights on.
I have had mechanics check all the usual suspects, belts, etc, but have not found anything amiss. Nor can I actually get the squeal to occur when I visit the mechanics.

2007 Sonata SE, 74,000 miles
Just took the car in for brake service (not the dealership) because of what I was convinced was a brake pad sensor warning sound - something I've heard with other cars I've had, and been correct about. However, the tech said the pads were fine.
The sound is a high pitched squeal, intermittent, coming from the passenger front wheel. It can be heard when coasting at moderate speed (30 mph or so), not so much when accelerating, and especially when turning left. It got worse today, with a low grinding sound at moderately slow braking speed that started after about two hours of start and stop driving (house hunting). The car has needed a couple re-alignments and will have to get checked for possible camber? adjustment (rear tires wore badly on outside edges, far less pronounced on front tires). Car has tendency to pull to the right.
Any thoughts on a main culprit here for the squealing-grinding noise or about the possible inter-relatedness of symptoms.

I just bought a 2006 F150 SuperCrew with a 5.4L engine and since the weather has turned cold, I've noticed an intermittent high pitched squeal coming from the engine compartment. I've replaced the serpentine belt and the idler pulley plus another belt pulley but none of the above worked.
I've also had two separate mechanics look at the problem and both are at a loss as to what could be causing the noise. The guess is maybe its an air leak coming from either the intake or vacuum lines. But nobody is really sure.
The noise seems to really become noticeable when the temperature gets below 20 degrees and around 2000 rpms, but sometimes it happens at other times. Where this extremely annoying sound might be coming from?

My truck started making this whistling sound a few thousand miles ago. Its a high pitched squeal coming from somewhere under the hood. There doesn't seem to be any pattern or certain time when it does it. Ive read on here about an alternator problem on these trucks. Or could it be my S&B intake?

I have a high pitched squeal coming from the back windows during operation. I am pretty confident it's not the window assembly itself (linkage, track, etc in the door), but rather the weatherstripping type material that physically lays against the glass at the bottom of the window opening on the door. This happens in both up and down directions of the window.
It DOES NOT squeal when the material is wet, and thus is the reason that I've been able to pinpoint the cause. It's likely that the window channels could be contributing to this as well. The problem is...I don't know how to solve this without applying a lubricant that will smear/streak my windows.
I've already taken clean rags and wiped both the inner and outer portions of this material to remove dirt and dust that they gather...no change in the noise. Is there a way to "condition" the material so they will soften up, without leaving a residue that will streak the window?

My 2002 PSD X with 258K miles has a high pitched squeal in the engine compartment. I only had a minute to look at it as my wife was leaving with it. But, I was able to stick my head under the hood and it seems like it is coming from the front of the engine. Trying to pinpoint where the squeal is coming from with all of the other engine noises is tough. I suspect one of the bearings up there like idler pulley, tensioner pulley, alternator, AC compressor, water pump. The alternator has about 70K miles. The other items I don't know.

This evening, my F150 with 2,600 miles developed a high pitched squeal, much like you might experience on an older vehicle with failing front brakes. Yes, that same squeal/grind the brakes make...metal on metal. It came in instantly while at highway speeds. It was VERY loud. The pitch didn't really change with speed...it was pretty consistant going slow or fast. There was no vibration, chatter or growl as I would expect with a failing bearing.
It was definately in the driveline/brakes. I was 10 miles away from a friends house, so I turned around and took it back to his place. Shortly after turning around, it quieted, only sounding when I would turn ( like a wheel bearing would when being side loaded ). I looked at the brake disks, thinking something was grinding on one of them. The outsides of the disks looked fine. Due to the shields on the inside, I couldn't see.
Later in the evening, I had to drive it back home, about 50 miles. Again, it was quiet unless turning fairly hard. By the time I got home, the squeal had turned into an intermitant growl/thump, as if a warped rotor was banging on the caliper. The noise was 1 to 1 with the rotation of the driveline. But still no vibration. Brakes work perfectly and the noise doesn't change with brake use. Backing up and turning hard results in a variety of sounds, including squeaks.
The hubs and CV joints felt cool. The brake disks were not hot as if they were dragging.
It is 4x4 / 3.7l

I have a 2006 350. When I am pulling my camp trailer (about 12,500 lbs) up a grade I hear a fan or blower turn on and I get a high pitched squeal. It will also have a beep and my in dash display will say high engine temp. I have a bullydog pmt programmer (i tow with it in stock mode) the display will show my coolant temp at about 180 degrees. If I pull over and let it idle for about 2 minutes the warning clears and the temp gauge returns to normal. the display reads about 180 degrees the whole time this goes on. I know the engine is not over heating so why do i get this warning and squeal?

Driving yesterday with A/C on & I start to hear this high-pitched squeal from the engine compartment. It sounds like an annoying cell phone ringing constantly.
It only occurs in motion under full or partial engine load (or in drive w/ PB engaged) with the A/C on. It's coming from the front of the engine compartment.

While driving home tonight in the snow, about half away home I noticed the most god awful high pitched squeal sound coming from what sounded like the back passenger side of the car. The squeal was so loud it made me cringe. I couldn't really get any near 40 mph because I could hear it start and instantly it would become really loud and would only stop when I slow down almost completely and then maintain a speed around 30 mph. It's pitch black out so I couldn't conduct a real thorough inspection however a quick look over and I didn't see anything wrong.

Ok, I replaced the head gaskets on this truck a couple years back and now I am having symptoms similar to the ones I was having then. I am not entirely convinced that this is what is wrong however.
Symptoms:
Truck was idling rough until it warmed up
Truck takes forever to warm up or simply does not warm up
If/when it warms up it operates at higher than normal temp/almost overheats(it hasn't overheated yet)
Heater blows very cold air
White smoke(has been cold outside so not sure if due to temp or coolant)
Overflow bubbled when I shut the truck off, but it has only happened once so far
I am kind of at a loss, but like I said am suspicious of the head gaskets.

I recently purchased a used 2009 Kia Rio. I really am enjoying the car. While there is nothing fancy to it, it gets me to and from work and that's basically what I need. However, when I apply the brakes, there is a high-pitched squeal that is made until the car is almost at a stop. It does this I would say 90% of the time. The brakes work just fine and are in fact very sensitive. I've tried researching this online and it seems a lot of people have this problem because of the type of brake pad used. The dealership I purchased it from is more than an hour away from my home, so I am reluctant to drive down there if there really is nothing that will be done.

So, last week, I heard this high pitched squeal coming from the wheel well. At low speeds it seemed. It was in a parking garage.
But then, it disappeared. All of a sudden, I'm reversing into a spot barely touching the brake and it's squealing again.
I then take it again for a spin around the garage, no sound. I reverse again, no sound.
A few days later, I'm pulling out of the garage and the sound is so loud my GF could hear it from within another car behind me. It squeals until I start going faster and I'm on the highway. I get to my destination, ask my friend who is good with cars to check it out. But of course, I couldn't recreate the sound. Tried going slow, backing up, braking, going faster, etc.
So, do you know of a sound that would be very loud one day and completely go away the next? I saw some things about a shim or clip on the brake pad possibly touching the rotor or is loose?

I did a search for this symptom but didn't see anything that sounded right... High pitched squeal from right front wheel well area (sounds like a tea kettle actually).
Starts at 10+mph and is speed variable (faster=louder)... but not effected by applying the brakes (so doesn't seem to be related to the brake assembly)... It doesn't happen all the time... but getting more frequent... annoying...
wheel bearing?
air suspension?
What it could be?

Have a very high pitched squeal on cold starts as well as when idle occasionally.
Bad compressor?

I have been hearing an intermittent high pitched squeal at 50 MPH and higher. Taking my foot off the gas or taking it out of gear doesn't change the noise. Hitting a bump or tapping the brakes makes it stop momentarily. It sounds like it is coming from the front driver side, though it's hard to tell.
I have about 33,000 miles on the car. My manual says that the brake pad replacement indicator should squeal when the brakes are applied.

While driving, I occasionally hear a hiss, which seems to be a/c related. but just recently, I've heard an extremely high-pitched squeal/whistle. So high-pitched I had to slow down, turn off the music, and tell my wife to stop talking :P to hear it. Brakes are not being pressed. Definitely not a brake problem. How do I know? I parked the car, with engine running, opened the hood, and looked for the sound. nothing. I turned off the car and was walking inside when i heard it whistling behind me, mockingly. it stopped shortly after.
I'm thinking it might be a/c related, or some kind of pressure hose. (a/c is working fine otherwise, as far as i know). It's not air leaking from the tire. I've heard it on and off for about a week and the tire pressure is fine.
I'm more mechanical with computers than cars, but i have a basic understanding. it seems to be coming from the driver side, under the dash/under the hood.

I bought the 2 door 2012 Golf 3 weeks ago and I noticed that whenever I roll the passenger window up or down, there is a high pitched squeal somewhere, I think out of the speakers. It's kind of annoying. If I knew the problem, I could just add a low pass filter, but I don't want to really go that route.

I have a 1987 ranger 2.9 V6. Have a intermittent miss @ idle when warmed up. What is the proper way to pull the codes from the computer, i,st something about counting flashes or lights...

A high pitched squeal appears to come from the front of the a/c compressor whenever the clutch engages. When the clutch disengages the compressor stops spinning, and the squeal stops. I can watch and listen to this as the system cycles with the a/c switched on. If I turn off the a/c, no squeal. I'm guessing the bearings in the compressor are going out. However, the system still cools normally, so apparently no gas has leaked out.
Does this imply the compressor must be replaced, or could injection of some oil into the system possibly fix it...?
This car only has 73,000 miles on it. I've owned 2 other TB's and a couple classic Mustangs with much higher miles and never seen an a/c compressor bearings fail.

Reading thru all the squealing noise posts made me want to ask about mine. I have started to notice a high pitched squeal/squeak that occurs while sitting stopped with your foot on the brake...then let off the brake and take off and get this momentary squeak that doesn't continue (at least I can't hear it). It seems to stop once you get going again.
Seems to be coming from the passenger side front. I think I started noticing this after my most recent tire rotation and balance. What the brake wear indicator sounds like or if I will get an icon on the mfi when the brakes need service. The brakes do not squeal when in use. I currently have 27000 miles.
