Ford Super Duty (1999-2016) :: Squeaking Sound Coming From Under Hood In Reverse But Not Moving
Jun 8, 2014
So today I was backing up my 11000# fifth wheel at the campground when at 1500-2000 rpm I hear this awful shrieking sound coming from under the hood. I heard it the whole time while backing up and under a load. I never heard it once going forward. So when I get home I put it in reverse and hold the brakes and again I hear this shrieking sound coming from under the hood I get it up to 1500 rpms or so not moving just holding it and the more throttle i apply the louder the shrieking gets.
Now remember the truck is not moving its just spooled up, holding the brakes. I think that maybe something is wrong with the turbo, but I dont want to jump to conclusions. This truck is a 2001 F350 SRW CC LB 7.3 161,000 2 owner miles, 4 inch turbo back FLO PRO Straight pipe, and gauges everything else stock. What is moving that is making this horrible sound.

My 2001 F250 5.4 has started to make a screeching sound. It only happens when it is in gear (auto) moving forwards or in reverse, and increases in pitch relative to engine speed rather than road speed, and is much more noticeable under mild to moderate acceleration. Maybe I actually mean transmission input speed?
When simply maintaining road speed, it is almost silent. Anyway, if I drop it into neutral while driving, the sound stops, and starts again when I put it back into gear.
From the drivers seat and with the windows closed, it sounds as though it is coming from the engine bay at steering column height, although this is really tough to gauge while actually looking where I am going. With windows open, it comes from both sides of the vehicle.
1st thought is tranny......
2nd thought is a water pump bearing, although there are no apparent cooling problems or leaks.
3rd thought is the alternator bearing, although there are no charging problems.
I say alternator because I recently changed the serpentine belt and noticed that the alternator made a very faint screech-like sound when spun without the belt on it. The main screech was there before I changed the belt. Maybe it gets really loud under load?
So I'm kinda scratching my bean and wondering what expensive piece of mechanics I'm going to shell out for next. If it's #2 or #3, I can do those myself, but if it's #1.... it likely means more money than I have to spare.
I did wonder about removing the serpentine belt and driving a very short distance (end of the driveway and back) to see if I can remove the pulleys, tensioner or other belt driven parts from the equation. Maybe this is not such a smart idea. I'm somewhat at a loss right now.

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?

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 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?

Is there a way to grease the steering shaft or whatever is making the squeaking sound inside the cab when I turn the wheel? It's a 2001 F250 CCSB Lariat and it drives me crazy hearing sounds I shouldn't be hearing. This is certainly not coming from outside the cab but rather in the steering shaft within the cab somewhere. How I can lube that up?

we've had a bunch of snow this week and I've been driving around with my hubs locked in. today I noticed when I was slowing down to pull into my driveway I could hear a slight squeaking sound(sounded like a squeaky belt) coming from the front.
I verified it was coming from underneath the truck behind the engine compartment so I unlocked the hubs and went for a drive, the sound was gone. I crawled underneath and turned the front driveshaft by hand and I could hear a slight rubbing sound at the back of the pinion. The bearing doesn't have any play in and there are no leaks. What is going on? Could the bearing be starting to fail or could the rubber seal around the pinion have some grit in it causing the noise?

I have a '12 F250 w/ 6.7 diesel. Lately when I turn off the ignition after a few seconds I hear a noise that sounds like a small electric pump coming from under the hood on the passenger side.
This also happened a while back but at the time the service people said they could not get it to do that and it eventually stopped.

So yesterday we were towing our camper home from a weekend trip. We were pulling on the interstate at about 70mph, up a slight grade into a strong headwind. The outside temp was about 85 degrees, so not too hot out. After about 5 miles I got antifreeze sprayed on my windshield, coming from under the left front corner of the hood. The water temp held at about 220 degrees where it usually runs when towing hard but the oil temperature steadily worked up to about 240 degrees. I limped to the nearest place to stop and pulled over to let it cool down.
After it cooled down I added water to bring it back up to the minimum mark. We were 200 miles from home on a Sunday so I stopped in the local Wal Mart and picked up a can of stop leak and poured that in then we hit the road again. About 10 miles down the road the water again sprayed onto the windshield and the oil temp came up, this time hitting about 260. The water temp stayed between 218 and 220, once working up to 225, so I slowed down and the temps came down. I was able to creep along and made it 50 miles to a relatives house where I let it cool again and added more water.
When we hit the road again we made it about 10 miles and the oil temp had worked back up to 240, water temp stayed around 218 so I stopped at my parents house and dropped the camper. We drove the 100 miles home from there without the camper. The water temp stayed around 195 and the oil temp held at 212. If I got over 60mph the oil temp came up, but keeping it under 60 the temp held. So, what is wrong with my truck? Is the oil temp up because I was a gallon and a half low on water? The most I had to put in was a gallon and a half. Did I plug the oil cooler up with the stop leak?
The oil temp when towing has always ran 12 to 18 degrees higher than the water temp. I forgot to add, 2005 F350 with the 6.0 diesel. 240,000 miles on the truck. I have owned it just under a year and don't know a lot about it. I don't know if it has had any work done to it prior to my owning it, the antifreeze looks orange or yellow colored.

So as of 2 weeks ago there is a popping sound coming from somewhere behind the cab when I'm turning in reverse. Its intermittent and only happens once or twice when I'm pulling out of a parking spot. It doesn't happen every time. Probably about 4 times a week but it only happens when its cold and been sitting. It doesn't happen when I'm driving in 2wd or 4wd. I was wondering what it could be and if its gonna be something I can afford to hold off on for awhile.

I continuously read that people with 6.2 F250s averaging 13 mpg or so in a combination city/highway driving. This 2014 4x4 barely has enough power to move itself (honestly, I'd rather have my Ram 1500 back) and barely gets 10mpg. Basically have to give it about half-pedal to even get up to freeway speed and floor it if i want to pass anything. Is it just that much of a POS or does this not sound right? Other than a massive "clunk" sound when shifting from reverse to drive or vice versa, no indication of any problems.

I had a pretty good clunk going on and found the passenger tie rod was shot. The rest of the steer components looked fine. Fixed it and still get a nice bunch of clunks. Went over the steering again with someone rotating the wheel and didn't notice any crazy movements. The drag link twisted a bit but the joints looked solid compared to the tie rod which was completely shot.
So I decided to dig into it today. Looked again and nothing. So I took it into my back yard to drive over some humps left from stump grinding. Clunk, clunk, clunk. I stuck my head out the window and wouldn't you know it the sound seems to be coming from the rear! Took a pry bar to parts like the sway bar links, shocks, etc.... can't detect anything. Maybe a u-joint? Gotta dig in I guess.
Also my rear springs creak like nothing I've ever heard. Dirt roads it's just creak, creak, creak.

My 99 super duty v-10 has 227,000 miles. It was a former UHaul unit but seems in good shape considering the abuse it's probably had! I recently started hearing a clattering sound coming from the rear.
Not just turning but in straight line. Very loud even at 2-3 mph, more pronounced in deceleration. I can best describe it as someone shaking a metal pail with about a half dozen lug nuts in it.
Previous threads point at the limited slip. I called the Uhaul after sales desk and he right away said put some friction modifier in and do figure. Eights in the parking lot. I did and The sound is still there.
One poster said the factory LS is garbage and not worth rebuilding. They mentioned the TruTrac as a good replacement and I guess I'll investigate that further.

I have a 2000 F-250 Crew Cab with Lariate Trim package (not sure how that could be relevant to the issue, but it might be?) and auto locking Hubs. Recently, the truck has taken to making an intermittent grinding/Rubbing sound that comes seems to come from the wheels. I can not locate the sound exactly since it only happens when I'm Driving, I have never heard the sound at any speed lower than 20 mph or when the 4x4 is engaged either manually through he hubs or the selector in the cab when the hubs are in auto. All this leads me to think that I need to replace the autolocking hubs, but i'd like a second opinion (or even third) before I go to the trouble of replacing them.

My 11 cc lb 4x4 6.2 has a clunking/loose sound coming from the front end. It is prominent when going over small/medium bumps but not so much large bumps. I have had my local dealer and a couple local shops look at it and they all say everything checks out. It definitely seems like something is loose in the front suspension. I just put new Gabriel max control shocks on all four corners. I have no play in wheel bearings or ball joints. Tie rod ends also look fine.

I have a 2003 Ford F450 super duty xl. At first there was a loud clicking sound coming from under my dash. I charged the battery up and the sound went away but the truck will fire up but not turn over and start. I thought maybe it could be the relays but the clicking sound quit.

I was driving home the other day when all of a sudden all of my electronics in my truck turned off. Turned out when I got home my battery terminal was loose so it ended up shorting out. (fixed that) but when that happened my fuel was just under half way. The next day I filled up and was pulling a 3,000 pound trailer. My gas gauge didn't move at all, all weekend it was stuck at full until I actually went over a bump and it started moving down to a quarter. I knew here was no way I could go all weekend pulling a trailer and only lose a quarter of gas so I filled up again and was only be able to fill up 14 gallons.

With the tranny in neutral and clutch out is when it is the loudest. With the clutch in their is 0 noise. The sound is a spinning clacketing sound best I can describe. The clutch is 2yrs old and was installed by a local shop using all OEM parts, the fluid level is perfect and looks brand new. The sound has come on gradually over the past 6 months but now can be felt thru the floor at the top of the gears as a rumble. The funny thing is that their are no performance issues like grinding,popping out of gear,hard shifting,etc.
This is not rolling gear mesh it is very loud clacking clunking sound coming directly from the tranny, not the transfer case, nor rears or u joints. This is standing still. Sometimes it will be a little less loud if I roll to a stop in neutral with the clutch out as opposed to gearing down to a stop push clutch in goto neutral and letting clutch out.

I have a 2002 F350 with the triton 5.4. For the last week it has been running like crap. I just did my plugs about a month ago. I don't know if it's a miss fire or bad fuel or I don't know what it could be. It's a popping sound coming from my exhaust and when it happens I lose power. It happens off and on. One second it will run fine and normal and the next runs bad. What it could be. Today I just changed my fuel filter and added STP octane boost and fuel injector cleaner. Haven't seen a difference yet.
