My 2011 is making a strange humming sound after shutdown. It seems to be related to the normal waste gate sound. I have a video....

View 12 RepliesI am having an odd issue that i don't want to turn into a bigger one.
When I am sitting at a stop at idle and have the brake pressed i hear a humming sound and the pedal vibrates but when I am moving an press the brake it doesn't do it. Ive checked the pads all around they're fine brake fluid is fine it didn't start doing this till a few days ago.
I am just trying to figure this out before i end up going down the road one day and go to stop and have nothing there.
Truck was running fine. Stopped and got fuel. Then crank truck and after about 15 secs it shut itself off. Now it WILL turn over but it is very slow and sounds "tight". 2004 f350 6.0 4x4 auto. I'm leaning towards torque converter.
View 2 RepliesI have a 2011 f250 6.7, I park under my house everyday, so I am used to weird noises coming from my truck when I shut it off, but now that I just did a dpf and egr delete, and tuner, I noticed that my tuner doesn't shut down until the noise under the hood stops, which takes a few minutes to stop, I use to hear the air valve on the egr cooler shut when every got quiet, but I don't remember it lasting this long, any one else have a H&S mini max and it doesn't shut down right away? the place where I bought my mini maxx said it should shut down as soon as your head lights go out, but that's not the case, the headlights go out long before this noise stops and the tuner powers off
View 10 RepliesThe truck always made a few strange noises after shutdown, but this is new and annoying.
Here's the scenario: Truck is warm and no CEL. A few seconds after shutdown, I hear all the normal(?) noises and then a noise that sounds like a vacume pump running starts and continues for about 20 to 30 seconds. Cycling the key, but not starting the motor will cause the noise to happen again and again on each key on/off cycle.
The noise seems to be coming from the top front of the motor. Could this be fuel pressure bleeding off? Is there a check valve that is maybe not doing it's job??
My 6.7 makes a humming noise when i shut down my engine. Starts a little loud and gets softer at the end. it last maybe for a minute. But here's the catch if i stick the key back in the ignition it stops and as soon as i pull it out it starts again.
View 4 RepliesSo I changed my fuel filter today and everything went as planned. I replaced it with a Ford OEM filters. I drained the filter housing under the truck by turning the yellow thing 1/4 turn. I then used a wrench and changed the filter. I put the new gasket on there and and tightened back down until it mechanically stopped. I then changed the one under the hood. I then did the bleed procedure 10 times and the truck fired right up.
Now for the reason with the post. I am getting a humming noise from the lower filter. I can find the issue. The yellow thing if fully seated closed and the housing is tightened as far as it can go. Under the hood, both lines are snug and on there properly. I can't figure out what is causing the humming.
The truck fires right up and the noise seems to go away, but I get the humming noise each time I turn the key on. I know something isn't right. I drove the truck around the block and didn't get any codes, but I have to drive it tomorrow and I don't want to risk damage to the truck.Thoughts on things I should try?
2011 F-250 Lariat with 38,000 miles. What is the cause or source of humming or buzzing noise from the under the hood that starts once I turn the truck off and close the door? Lasts from 3-4 minutes and only started noticing it in the last two thousand miles or so.
View 13 RepliesSo with the hurricane coming to my house I did the balljoints on my drivers side yesterday to prepare to evacuate today. Everything went smooth with no problems. Now fast forward to the drive to Orlando, I hit a bump going 65 and my front right side (ball joint replacement side) starts humming. I pull over and it stops, get out see nothing obviously wrong and start back on my way with no noise to speak of. It happened again and again I just slowed to almost a stop and it went away. Yesterday after the repair I took it on a trip through some crappy roads, the freeway, and all that to ensure she was safe with no problems. Maybe it is the bearing failing all of a sudden (it looked fine when I took it off). I have had a vibration at 55 consistently i think is the tires now that I replaced the ball joints (was waiting to have the tire shop check balance until after the repair) maybe that could be it?
View 3 RepliesI just recently bought a 2011 powerstroke f250 and while running I can hear the fuel pump humming pretty loud. Is this a possibility that it's going out? Or is this normal?
View 3 RepliesI have 2003 f250 6.0, had the turbo rebuilt and I put it back in, my turbo is whistling but I'm also getting a humming noise kinda sounds like a when u down shift at high rpm's idk what's going on, I try and power break as well to build up boost and the tires do not even spin...
View 4 RepliesOn my way home from work the other day my 2000 7.3l started making a humming sound while driving. I noticed that it was shifting harder and it began to slam into gear when I would take off from a stop. By the time I pulled into the driveway I had to be half way into the pedal to keep it moving. I shifted into reverse and it clunked loudly and didn't want to back up. I don't know much about transmissions but I'm thinking that it's probably shot. I'm hoping that it's something other than a complete rebuild but doubtful.
View 6 RepliesI just bought a 11 f350 powerstroke. CC lariat 4x4 with 70k miles. Whenever i turn off the truck abt 30-45 seconds later a humming starts and continues for abt 1 minute. Sounds like a pump or a release of air? Is this a normal function or should i have it checked out. I've searched around but found very mixed answers.
View 4 RepliesI am trying to track down a leak ..... pretty bad one. I just filled with oil truck fired right up and it didnt appear to leak until I turned the motor off then its pouring down passenger side around the starter and into the drain pan. Any clue?? I am thinking pedestal does it usually leak more as the motor is turned off...
View 14 RepliesIt only happens on a very Rare occasion.
When Cold, and when I start out as I open the throttle, it suddenly sounds like there is not a piece of quieting stuff on the engine. I mean its like I can hear right into the engine itself.
I back off, It goes away then I dont hear it again for another Month or two.
Recently my brother in laws truck started making a buzzing sound while running and a much louder sound after it shuts off. Trying to track down the sound. Listen to the whole video because the end is where it gets loud.

So I have just over 14k on my 2015....... I love the truck but have had a few small issues. I had a water leak coming in from the roof that would leak through the grab handle. Nothing major dealer replaced one clearance light seal and they said the windshield needs to be re sealed.
Then I had a god awful irritating squeak in the dash..... It only does it late In the day when it's been hot. The dealer said it was a loose air bag. I have had the truck back a week and it's doing it again.
Those are little issues that will get resolved...... I hate having problems with a brand new vehicle but I understand it happens and that's what warranty is for.
I also reported a bad shake to the dealer...... The truck will shake very violently and have a very loud "diesel" sound. It's very specific at when it occurs. It has only done 4 times in the past 6 weeks including today. The odd thing is the 4 times it has done it has been the same time of day in the exact same spot on the exact same road!!!!
Basically I leave my office sit in some traffic and by the time I get to the parkway it has been35 minutes or so. Only happens in 6th at 60 which is roughly 1,400rpm a slight load due to a small incline and it shakes real bad! The typical "diesel" sound you get when under a load is very pronounced almost to a knock. It will continue to do this as you slowly increase throttle until it down shifts and then goes away. I also caught it doing it and I manually shifted to 5th and it went away.
Because of the rpm at which it happens with slight load only doing it in 6th I lean to a Trans issue and more so a converter problem. It feels like converter shutter. I just don't understand the engine sound.
I gave very descriptive info to the dealer..... Several techs drove it and could not duplicate. I just picked the truck back up last Thursday and the dash squeak is back and the shake happened yesterday and again today. So I am a bit irritated to say the least.
I really hate the fact that I know there is a problem but I also understand if a tech can't duplicate it he can't diagnose it. However today I did get a video of it with my phone so they will know I'm not making this crap up!
it's now 1,500 miles away on the side of the road.White smoke, knocking and lost power. Truck has 133,000 reman engine installed at 46,000. Is it common for hydro locking to bend a rod? He sent a video and it def sounds like a rod and degas is empty.
View 9 RepliesMy power steering pump was making a loud whining sound. No problem, changed the pump. Now after the truck is started I will have no power steering or brake assist, give the truck a little gas and you can hear the power steering pump "start". I have tried every way to get the air out, or is that not the problem. I even lifted the front of the truck off the ground with a forklift and with the truck off turned the wheel about six times stop to stop. Fluid level looks good and has since adding after the change.
View 4 RepliesNew to the 6 liter powerstroke recently upgraded from my 7.3. Recently this odd whistle sound started and I can't quite seem to fogure out the cause. At first it only happened if I was going 70 mph and now it will do it anytime it builds more than 15lbs of boost. I tried tightening some clamps and stuff but that did nothing.

Last transmission service - unknown (I have owed the truck for 3,000 miles). I just acquired a clunking sound when shifting from R to P or R to N. No noise from N to D or lower or back up to D. It does not grind into gear, just clunks one time. It is rather loud.
All shifting while driving is normal, no slipping, or noise. This occurs on level ground, at operating temp, and +-650 RPMs.
Fluid level is okay. No strange odor. What will be the next steps to investigate?
