Ford Super Duty (1999-2016) :: Squeal Under The Hood While Engine Braking
Mar 29, 2017
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....

Truck seems to run ok, but when I push the brake pedal down a bit, a strange grinding/howling noise comes from the engine bay and same thing with the power steering. When I put the brake pedal down to the floor, it stops?

First off I want to say I love my 11 f350 6.3 srw she's a awesome truck. I pull a small 7x14 trailer for my biz..
(3600-400) is the usually weight, I always use my tow feature. One day last week I start out hit my button in go, but I notice the engine braking/down shifting wasn't working. The trans still shifts smooth n normal the light is on the dash but no tow engage.
I check the transmission wire plug to make sure it'd getting a good connection, it does. I take the rubber boot off next to the shifter look at those wires they look ok not pinch or nothing, so I'm stumped.

My truck was in 4x4 and would squeal all the time on and off. Here is the situation today, this has happened prior but i just didn't post on here until it lasted for 30 miles on the highway.
4x4 system:
-MM hubs
-all stock minus the hubs
-Pass side vac hose melted against tire (doesn't matter with the MM hubs but too much info is not a bad thing)
-Replaced u-joints in November
-the screeching when not engaged predates the MM hubs that i installed, it occurred when i had my auto hubs locked last year because they would not disengage
Trip:
-average of 45mph
-30 miles from NH to MA (route 3)
-truck was operating up to temp
When it occurs:
-Under Acceleration
-15-45 mph
- when going from stop-30 it makes a hollow tapping noise instead of the screech
- when hubs are locked and t-case is NOT engaged it screeches for about 1 miles and then stops
Sound in the video occurs within the first 8 seconds, its faint in he video but very loud in person. Highway didn't look that bad in the video but i was in a plowed sctretch other than that the last 25 miles were through about an inch of snow and slush.

I have a 2013 f350 with the 6.2L gas and automatic transmission...when it sits idling in gear or park it starts to whine or squeal for about 30 seconds then stops and starts again. it makes a horrible sound if you shut the truck off while it's making the noise... Ford has had the truck for 5 weeks and checked the motor for vacuum leaks and changed the torque converter...but it's still doing it but less frequently now but according to them it's louder. I have a video but don't know how to upload it. if you go to YouTube and search ford raptor whine it shows a raptor making the same noise also.

At low speeds, I notice a squeel sound in all four wheels. Ford tells me that it is due to the type of metallic pads they use and is essentially brake dust noise that warrants no repair.
Any after market pads that are good quality for towing heavy loads, yet aren't metallic in composition? For instance, are porcelin pads a good choice.

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?

So today pulling out of the gas station I turned my steering wheel to the left and I heard a high pitch squeal from the drivers side. It wouldn't do it again unless I was just creeping, nothing going down the road. I did a few searches on here but they all are if the truck is moving say 30 mph or better. I know I need to replace my ball joints. 99 F250, V10, 4X4, extended cab.

I have an 2001 Ford F250 V10 CCSB. I installed 3157 LED Brake//Turn light. Now when I turn in my left turn signal it blinks fast which I can live with that but it would be nice if it blinked at the regular phase. Here my big problem. When I turn on my right turn signal there's a loud squeal in the cab of my truck. !!!

2015 with a 6.2 and 1200 miles. I have a whistle coming from under the hood. I didn't here it at first with the windows up and AC on but now that its cooler I have the windows open. I only here it at 2000 RPM or under while accelerating. Doesn't seem to matter how hard I am on the pedal or how heavy the load.
Dealer is going to have to fix it but would like to get a heads up for what it could be.

I noticed a raw fuel smell today while driving. I came right back home & found fuel spread all over the under carriage. I popped the hood & found the fuel bowl and surrounding area wet as well as fuel puddled up in the valley.
Before I tear into things I'd like to get input about common causes. I've read that the separator valve gets it's o-rings eaten up by modern fuel. Could this possibly be it? If so are there special kits that deal with the low sulfur & biodeisel?

I have a 2004 F350 Crew Cab DRW 4WD 6.0L.
The front drive shaft is making a high pitched metallic squeal while the truck is in motion. I thought it might be the universal joints but after lubricating the joints, I can still hear the squeal and it sounds like it is coming from inside the drive shaft. I also hear this squeal when I spin the drive shaft by hand.
I have quite a few questions about these drive shafts:
- What would cause a squeal from within the drive shaft?
- Are there any replaceable parts or do I have to get a new drive shaft?
- How do I identify the correct drive shaft part for my truck? Seems like there are a LOT of different models on the web.
- Are any of the aftermarket drive shafts any good? Any to avoid?
- Is this a DIY job or will I need to take it in to the shop?

5.4L f250 is dead. Went through a small mud hole and the he truck just died. The muddy h20 was about 1/2 way up on my tires. After getting pulled out I checked the air filter and its dry. I did notice that the insulation on the hood was wet towards the back half of the engine. Guess maybe the fan sprayed it up there. Tried starter fluid with no luck. Just turns over. Also checked the fuel reset and its normal. Where should I start.

So it was -10 last night didn't have my truck plugged in fired it up this morning took a few cranks but started heard a wine under the hood figured it was cold let it warm up for a half hour went to a buddy's for a party left a few hours later driving home truck was up to temp running fine then I thought I heard a wine again turned my music off rolled my windows down and it sounded like a Cummings lopping shaking like crazy lost power couldn't make it up a hill and bogged out and died look under it and has some oil on the axle tube called for a tow truck ten time no answers so I tried to fire up again and stared and ran fine made it home no problems. My question is is it a fuel issue I use anti gel every fill up but is it still possible maybe water? Or could it be my hpop it hasn't thrown any codes or lights all pressures and gauges read fine. Also my rear main leaks along with oil pan was it just some water running through or should I be worried...

I have searched and tried everything that was suggested to open the hood on my 2000 and nothing works. When looking form the front you can see the hood release operate, but nothing happens. What part of the release do I need to operate to get the hood to open?

2011 F-350 XL, I can hear a squeal coming from the front brakes when rolling forward slowly, believe the pads are dragging on the rotors. If I touch the brake pedal the squeal stops as it does when I turn the wheel. Took the calipers off and greased the slide pins and put it all back together, still got the squeal. What don't I know???

Battery tested good, tried jumping it as well with cables and with portable pack.
I hear two clicks under the hood (NOT a continuous type click you hear when the battery is dead). The first seems to be up near the passenger fender well when the key is turn to the start position, the second click seems to be down under the motor near the passenger side (near the starter I assume, couldn't tell very well) when the key is RELEASED from the start position. The motor doesn't budge, I don't see any belts flinch or pulleys move to indicate that the starter is engaging. I don't hear anything that sounds like a starter engaging to me.
If not, where the starter solenoid is on this thing? is it separate like the other older ford's I've owned or is it now on the starter? Is there any fuse-able links that could cause this? Wiring diagram? Is there a way to jump the solenoid like in the old school days (e.g. with a screwdriver or wrench)? would like to get this home without towing it or fixing what is really wrong with it in the parking lot.
It's in negative to single digit temps here in Indy now, I fired it up in the morning in negative temps, drove it work. Came out to go home, and now this. So something happened between this morning and now and it's not the battery.

I have a 2000 Ford F-350 V10 Triton that is currently not running. It all started when I was going to work at 7:00am it just shut off in the middle of the road. I had someone to take out of the road and found out one of the fuses had blown. It was replaced and not even a mile down the road it died again, luckily next to Orielly's. They came out and did a test and found out it was coil 10. I purchased and installed a new one and went down the road only to have it die again. I replaced the fuse again, and went back to Oriellys and just as I was backing into the parking spot it died, this time smoke coming from under the hood. The brand new coil had caught on fire but I extinguished the flame and got the coil unplugged before any damage happened. Replaced the same coil and it ran fine until I got home, let it idle and it was fine. Then, two days later I started it and it died, again smoke coming from under the hood but no flames or fire. Now cylinder 10 does not fire any more. What the cause is?

I got to replace mine because the hood won't stay up on it's own and is heavy to lift. I was wondering if these things fail often. Mine is an '08.

03 F250. 5.4 2v ... I purchased it a month ago.
Squeak under the hood. It appeared to squeak in relation to the movement of the tensioner......simple right? Replaced Tensioner and Belt..... Still squeaking.
AC not working at all. Compressor never kicking on.....replaced compressor, accumulator, and orifice tube. AC works now!.....squeak still there....
Notice fan wobbling.....shut truck off.....fan clutch shot... replaced....STILL SQUEAKING!!
Obvious answer....sound still on that side of the engine....Idler pulley....I just replaced it and the dang truck is still squeaking!!!!!!!!!
All that's left is the harmonic balancer, alternator, and power steering pump.......What could it be?

Twice I open the hood of my SD and I see water pooled up around the intake manifold on my 2001 F250 5.4. This happen when we have heavy rain. My truck is sitting on my drive way that has some angle to it. When it rains, all the water from the roof flows down the windshield and somehow the water is getting into the engine bay.
I cleaned out all the leaves and made sure the rubber molding were in place near the firewall, but it happen again last night. Is there something wrong with my truck to keep the water out. I suppose I could turn the truck around so that the rain will flow from the roof to the bed. But, I like parking my truck the way I park it.
