Ford Excursion :: Screech / Squeal Coming From Under The Hood While Driving
Apr 6, 2016
On the way home tonight, the Ex started to make what I can best describe as a screech/squeal. It sounds a little bit like a pulley spinning against a stuck belt or a motor that ran out of grease. I heard it 4 times and it lasted about a second or 2 each time. It seems to be coming from under the hood. The only common variable between all of the occurrences is a speed between 5 - 20 mph.
Belt has been replaced recently, when I looked under the hood all pulleys were spinning normally. The only thing I can think of is maybe it's the re-manufactured power steering pump that I put in after the redhead box install or the a/c compressor. When the compressor is running it makes a ticking noise. Maybe it's finally done and the screech is it starting to spin up when it engages the pulley?

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.

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've got a strange squeal sound coming from under the hood only when truck is cold? It sounds like a bearing and after it gets heated up the sound stops. I talked with a guy thats a cummins guy and he said he had a similar issue and he had to replace the bearing in the turbo? Also when truck is warm it will still do it, like for instance, if I run in a store and truck idles for 5-10 mins it will do it only if I romp on it for a short while like 2-3 mins then again goes away. And if I'm idling or in neutral, hot/cold, it does not do it, it seems to be only under a load. Pull a 26 foot boat no problems.

My Superduty will randomly squeel for a few seconds or just one. It seems to happen randomly. The hub doesn't have play.

I've been experiencing a loud clutch squeal or screech when I first engage the clutch after the car has been sitting for longer periods of time, overnight etc. It goes away after a few shifts and only returns after the car sits for a long period.
I brought it to the VW dealership since I'm still under warranty for a bit. After two visits the have come up with two hypotheses without any evidence. They claim to have not heard it or found anything wrong visually.
1) it could be a rear main seal leak. Or leak from somewhere on the tranny onto the cultch. When I first drive it is burned or wiped away. After putting on the lift they found no evidence of leaks. So hypothesis two:
2) Thy flywheel may be developing a bit of a patina of rust. After the clutch is engaged a few times, the rust is gone and the squeal goes away.

I have a 2002 Nissan Sentra (manual transmission). I recently started noticing this horrible metal screech/squeal/scraping sound when my car starts moving from a stopped position. It's the worst when the car starts moving after it's been still for a bit. I thought it was due to the cold weather because when it started getting warmer, the noise issue went away. Unfortunately, the weather is warm, and it's back in full force.
The noise almost sounds like the noise that some semi-trucks (or large buses) make when they press on the brake. But my car only makes the noise when it starts moving and it only lasts a few seconds. It also doesn't happen every single time, which makes it even more frustrating.
I've got about 115,000 miles on the car...

The wife drove the Excursion (V10) to work today and it ran normal and didn't have any loud noises coming from under the hood. When she started the engine to return home it immediately started knocking. This is not a ping, but a knock. Not a loud heavy knock, but much louder than a ping. It has a fast frequency, seems too fast to be a rod knocking. The frequency is similar to a valve issue, but the knock seems to be too heavy for lifters. Oil looks good. Just changed out 2 weeks ago. Truck is driven everyday.

I have a 2000 2wd with the 5.4 in it. I tow a travel trailer and loaded is 6500lbs. Today leaving the campground I had to climb an extremely steep hill as soon as you left the campground. No time to build speed. The old Ex made it, but I was definitely worried. The truck ran fine the rest of the 2 hours home. I went to back my camper into its spot to store, and smoke started coming out from under the hood. When I crawled under it, tranny fluid was leaking on the ground. A pretty steady drip. I let it cool down, added fluid and drove around. Didn't leak anymore. Did the tranny just get hot and had to burp? The drip was coming from where the tranny connects to the motor.

A little background info...up until about 6 months ago my 01 Ex V10 was a grocery getter for the wife; only got a few thousand miles a year for the most part. Since we moved from Washington state to Texas it has turned into my daily driver (after a 2500 mile drive towing 8k trailer).
A couple of weeks ago we were running errands and after we got home there was smoke coming from under the hood, but I couldn't pin point it. I let it be because I figure it would let me know when something was really wrong. A few days later it did it again but this time I found the problem; transmission fluid was leaking out of the bell housing onto the y-pipe. I did my research and come to find out it is most likely the front pump seal that got soft from overheating. So my buddy and I drop the transmission and replace the seal. Put it all back together and everything seems great.
Another week goes by and we have driven the Ex fairly extensively around town and even took a couple short day trips and everything is great. Then as we are turning onto an on ramp to get on the highway I give it gas to speed up and all of a sudden the RPMs climb like it dropped into neutral. I had enough momentum that I got over onto the shoulder and started to check thing under the hood. Looked like I was low on trans fluid; ok so I added a quart. Put it in "D" and still nothing. Then I try "1", "2", "R" and they all work fine.

Okay so 2007 F350 DWR here, I have a driver who hauls loads using the truck and a 25' gooseneck trailer. She's gone through the bullet proofing process at 80K miles, she now has 128K miles. I have a programmer to monitor temps, and do all required maintenance.
With that said, my driver reported last week that when under load and going up hills he got the white spray coming out from under the hood. See pics below, this is never really good of course but I want to believe its not catastrophic. Two weeks prior I changed out the thermostat and upper radiator hose and of course flushed and filled coolant, all was good - no hoses were loose, etc. Driver reports the truck did not overheat at any time.
Both ECT and EOT are within 10-12 degrees of each other, and did not go over 190 for me while driving around town the other day. There are no codes present, I cleaned the engine bay and drove and re-inspected but can't tell where the coolant is coming from as none appears to be leaking. Last note, I have to admit after driving for a day or two I had to fill the degas bottle up about 3/4 gallon of water. My questions is, what is the next step for me in the diagnostic process?

A few weeks ago I heard my car was making this weird noise in the morning, when I go really slow, like when I'm parking in reverse or just getting out of my garage in neutral. It comes from the tires, I don't think the problem is in my breaks, because it doesn't make that sound when I'm breaking and I took my car to the dealer (forgot to mention the sound to them) but they said everything was fine, so my brakes should be fine...
Usually the car makes that squeal-sound in the morning. The sound goes away after I start driving on normal speed (40-45mph).

I have a 2001 F150 4x4 supercrew XLT 4.6 with 150,000 miles. I have a few things happening in the truck, and although it is still running for now, I would like to get ahead of this before something catastrophic happens, and I don't know if everything is related, or everything is falling apart separately.
1. I have been noticing a burning smell coming from under the hood after driving, every time I drive, but no noticeable leaks, and oil level is fine. I have seen light smoke coming from the exhaust but inconsistently. A mechanic said it was probably the valve cover seals leaking to the manifold, but I would think there would eventually be less oil on the dipstick?
2. When on the gas, over 2200 RPMish, the air and AC switches to defrost. It seems like a vacuum line leak somewhere, but can't find it.
3. Generally, the truck seems sluggish, sometimes unwilling to shift gears or accelerate at freeway speeds. Not sure if its the transmission going out again (had it replaced at 125000), or spark plugs?

The last week or so I have been having a screeching belt sound driving me insane in my 2003 F-250 7.3. After further investigating I have found out it is coming from my 11 month old GTP38R bearing. It has an aftermarket billet compressor wheel in it and I sold the factory wheel when I installed the Billet wheel. Where to locate a factory Garrett GTP38R wheel? All I can find online are Billet wheels or random off brands. At this point I would even trade my Billet wheel for a factory 38R wheel.

So I've begun to notice an annoying intermittent squeak/screech in my steering column while driving, obviously aggravated by the rough roads we've got down here. I can silence it tho, if I push in/up real hard on the steering wheel, so I'm pretty confident there's some bushing or bearing in the steering column that needs some lube or maybe just outright replacement.

While engine braking I started hearing a squeal under the hood , when I started accelerating it became a little louder, I pulled over and when I rev it up it gets louder and has a little rattle sound, sounds like it coming from the turbo....

My wife was driving the car on the freeway and flames started coming out of the hood/vents/etc. We just picked the car up from service on Friday...Today is Monday. Whats the standard protocol for a car that's is still under warranty that goes up in flames?

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.

Swapped for Warn standard hubs a few months back when the ESOF's turned out to be trashed.
Since then, I've noticed a rattle coming from the hubs when driving over rough or broken pavement. I've checked the outer caps and they're good and snug, proper amount of grease inside, and the hub itself is completely secure.
Do aftermarket hubs have tis issue? It's not critical, but on cooler evenings with the windows down it sound like a rattle trap unless the roads are in good shape. More of a pet peeve I suppose, but still curious.

The Ex just started making a sound that I can best describe as a hiss or squeal, but not as much of a squeal as the belt were to make if it were slipping. It starts around 1700 rpm and gets louder as the revs increase. The truck also feels maybe a bit down on power but that just could be me not willing to push the gas as it squeals louder when I do. I don't see anything leaking and anything out of the ordinary under the hood. All gauges are normal, turning the a/c on or off doesn't change anything. Nor does the radio. Any clue as to what my problem is? I'm a little worried driving home if it's something potentially serious.

So I think it's time to change my belt on my 6.0. I came back from Fort Hood, started the beast back up, and heard the belt squeal loudly at first, then settle into a rhythmic squeak that at first seems to intensify with RPM, then seems to die out at highway speed.
On every car I've ever owned, when the time came to change out serpentine or fan belts, I would also change tensioners and idlers. Is this necessary on these trucks? Or something I should do for peace of mind? Or not at all?
