Ford Super Duty (1999-2016) :: Screeching Sound Only Happens When In Gear (auto) Moving Forward Or In Reverse
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.
Ford Super Duty (1999-2016) :: A/C Blows Form Defrost Only - Vacuum Pump?
Its hot in St. Louis and my windshield sure is staying cold (ac blows from defrost vents only).
1999 Ford F350 7.3 diesel 4x4 (4x4 lever on the floor). About a month ago, the ac starts blowing out of the defrost vents only. I assumed it was a vacuum issue.
Lines looked good; very plyable still. Canister looked fine. The vacuum pump on the pass fender well smelled burnt, so I replaced it. Got the new pump in and it didn't work. Checked the fuse panel and found two blown fuses, replaced them and the pump worked.
Here's my issues: if AC max is used, the vacuum pump stops working and air blows through defrost only . If the dash switch is in the off position and then turned back on, air blows through defrost vents again and vacuum pump will not work.
Is there a solenoid or switch to this vacuum pump that I'm not seeing?
Ford Super Duty (1999-2016) :: 2003 - Clicking Noise Form Front While Driving?
2003 F350 4.4 5.4L auto. The front hub assemblies, seals, axle ujoints and upper/lower ball joint were all replaced. I bought all the parts gave them to the mechanic and told him if there's problems call me. I took a week off went to MS and he never called. I go to get truck he tells me, the bearings in the hubs are not spinning freely causing the axles to spin. I checked the hubs they are in the unlock position (Warn manual hubs). Originally auto hubs. Now i have the whole front diff spinning and the front drive shaft is spinning too. Clacking and clicking from the front wgen driving. Oh he said the front drive shaft ujoint was bad also. I paid $600 to have it all replaced and i get it back wrong. Is there something i need to check on the hubs that he maybe did wrong? Or is it possible i was sold the wrong hub assemblies?

Noticed this morning that the truck appears to have a screeching/grinding noise while going straight down the road. If I go a bit of speed and stop the engine and exhaust from revving and making noise and just let it roll I can hear it and hear it better by sticking my head out my window. My engine and 5" straight pipe hide it well while im going though. I think its coming from my front driver side but im not 100% exactly sure. What it could be? I know there are a lot of variables to cover but any ways to check things out? Also! I can hear it slightly while reversing slowly.
View 8 RepliesFord Super Duty (1999-2016) :: Rebuilding Turbo - Screeching Noise At Start - Shut Down
I recently pulled the stock tp38 off. The reason for rebuilding is the turbo started making an awful screeching on start up and shutdown when the compressor is at a low rpm and starts to wobble.
The shaft has 1/2 in and out play with 1/8 in every direction. the compressor has some wear marks but no chips, the turbine has some good chunks missing. from what i can see there are no marks on the housings.
What should i put in it as far as new compressor and turbine/shaft. nothing that requires machining. I am not looking to run more boost or anything, just looking to reduce spool up time if possible. Any specific rebuild kit? what turbine and compressor should I go with?
Ford Super Duty (1999-2016) :: 2004 F250 - High Screeching Noise When AC Turned On
I have an 04 F250 6.0L and for the last month or so when I turn on my AC it makes a high screetching noise but only last for a little bit. Had a friend that works on cars on the side take a look at it one day and he said it was the AC cutch trying to engage. Does this sound like what it could be? Also if it is can it be changed out without having to remove the compressor? What all is involved in changing it out?

Trying to find a bit of information for my dad. He has a 2008 F250 with the 6.4L PS. It recently started making this horrible screech on his initial take off from park. After he let's off the gas and brakes, the truck won't make this noise again for the rest of the time it's on. He ended up replacing the turbo, and that did not resolve the issue. I believe the Y pipe was checked and it was fine. What it could be that would cause it only on the first acceleration?

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.
Ford Super Duty (1999-2016) :: Ticking Sound From The Right Side When Engine First Cranked
I'm assuming its a valve.
2004 F250 with 5.4L. 128,000 miles. Oil changed every 4K but its my work truck. She works hard for a living towing landscape trailers 98% of the time.
When the engine is first cranked, there is a ticking sound from the right side. Its quite noticeable but only does this until I get going. Once I get to driving, it fades away. If I turn the engine off and let it sit for a little while, when I start it, the ticking is back again. As long as I keep it running, it stays quiet.
If this is a valve or rocker arm, how big of a repair is it? What happens if I don't deal with it until the winter (off-season)?
I've tried Marvel Mystery Oil and now with this oil change, I have Rislone in there. Both have made no difference.

Why does my engine fan run when truck is cold? I hate it, anoying winding sound. It will run that way for up to ten miles sometimes. My other trucks never did this. This is the 6.2 gas.

Here's a link to a video where you can hear what I'm describing. The noise is most noticeable around the start (first 18 seconds) and the end of the video when I'm closest to the exhaust pipe:
YouTube ....
You may need headphones to hear it, but the engine seems to be making a bit of a puffing sound during idle. It happens completely randomly and I'm not quite sure what could be causing it.
Aside from this noise, the engine seems to idle normally, and the check engine light isn't on. I had all of the injectors out a few weeks ago for cleaning. They all appear to be working fine. I also cleaned the throttle body at that same time and ensured there were no obstructions for the air intake and filter.

I have 2009 F-450 6.4L Diesel with 41K miles and just started to have a noise that can be heard up in the CAB of the truck while driving or idling. It sounds like a dry ball bearing that would go bad in home computer AC power supply or CPU cooling fan. The sound starts when the engine is at full operating temperature and most noticeable and the loudest if you are standing in front of the engine at idle outside.
Checked all fluids and they are normal. Turning the steering wheel doesn't affect the sound either or turning off the AC. Check engine light has not come on. The only thing I have noticed is that clutch fan stays on a very long time after starting cold and takes about a mile or two before it disengages. The truck is only used to tow a 36' 5th wheel and sits the majority of the time.
