Ford Super Duty (1999-2016) :: Slight Humming / Vibration When Decelerating
Feb 14, 2016
I have an 08 F250 supercab 5.4L that I bought this past July. The truck has 153000 miles on it now it had 150000 when I bought it. I don't drive it every day just usually on weekends and when I need the truck. The truck was really well maintained and had all the work done at a local ford garage. I live in western pa and lately it has been pretty cold and snowy so I have been using the 4x4 more than I normally would the past few days. My wife was driving the truck the day before yesterday and had it in 4x4.
The past 2 nights it has been really cold right around 0 degrees. I drove the truck yesterday and it just didn't seem right when I first drove it almost like there was a tire going flat or a flat spot with one of the tires. I got out and checked and everything seemed ok but it was still doing that. I saw that the passenger side hub was still locked while the drivers side was on auto and I was in 2 wheel drive. When I got home I sprayed the hubs down with PB Blaster and tapped on them with a rubber mallet. I put the truck back in 4x4 and drove it down my road to the end then put it back in 2 wheel drive and reversed down the road. When I got back into my driveway and checked the hubs were both in auto so all was good. T
he only thing now is when I am driving everything is normal but when I start to brake or decelerate I get a humming noise like you would get with off road tires on the highway. I wouldn't say that it is that loud but definitely noticeable and there is a vibration in the floor in the front along with the humming. When I am going really slow decelerating you can also hear a noise similar to if you would spin one of those wheels with the metal pegs at a carnival or something to win a prize.

I recently had a close encounter with some large rocks on a bad road and broke the power steering cooler. I lost some fluid and pressure as I had no brakes and it steered like a log truck. Replaced the damaged part and added fluid. I was informed by ford technician that air in the lines would make noise but would eventually work itself out. Well the brakes work and steering is getting better but it is noisy with steering and brakes. How long should it take to get the air out? PS the fluid looks foamy now. I should also mention it was making a slight humming noise before the incident with the rock.

I bought this Ex a little over a month ago and finally got around to replacing some stuff.
I have a slight vibration between 50 and 60 MPH. The vibration is the same weather I am accelerating, in Neutral, Coasting down (well, a little bit worse when coasting down), in 2WD, in 4WD, turning, going straight, hot or cold.
I have replaced the following:
Rear Driveshaft U-Joints
Tires and Rims
Upper and Lower Ball Joints
Wheel Bearings
Steering Stabilizer
Cleaned and Greased the Hubs
Greased everything greasable up front
I still have the exact same vibration as when I started. I can feel the vibration in the steering wheel as well as in the body of the vehicle. I am thinking that it may be in the steering linkage. If there is a loose joint then the wheels would be allowed to jiggle a little bit. I am at a loss. What else should I check?
Also, When doing the ball joints, I noticed that the tie rod ends were quite stiff. How stiff should these be? I can't move them by hand, but they will move a little bit when moving the free end of the tie rod.
I am taking it in for an alignment on Friday, and if I can't figure this vibration out, I might have them take a quick look into it. Would a stuck slide pin in the front brakes do this? Both sides on my truck are seized at the current moment.

New, 2 month old 2015 CC, gas 4x4 with standard bed. At 50-55 I have a rolling vibration, or it can even be explained as a slight growl. Seems worse since I upgraded to 285/75/18 Toyo AT's and new wheels. If i speed up to about 60, goes away. If I pop it down to 5th gear, it seems to go away, however, I need to try this a few more times to make certain.

2002 Ford F250 4x4 Superduty Lariat (4 door). Just changed the locking hubs to a new set of Warn manuals. I began to periodically hear what sounds like a rumbling/bearingish/howling kinda sound. Happens when you hit a bump at any speed...then howls till you hit another bump..goes away..then process repeats. Come to a complete stop, and the sound usually goes away till you hit another bump. The hubs are "free" at this time.
Heres the weird thing...when the noise starts...I switch it into 4 wheel drive on the dash...the sound instantly goes away. Click it back outta 4 wheel drive (hubs are still unlocked this whole time) and the sound is gone. drive some more down the road, maybe hit a slight bump, and the sound returns. Switch it back into 4x4...sound instantly goes away. Its not really in 4 wheel drive, cause the hubs aren't locked in...but that cures it till I take it back out. What could be causing this howling ? Its getting worse, and you can feel a slight vibration in the floor now when its doing it.

The truck is in my Sig 01 F250 5.4
Just got back from a long trip with it. Parked it for 3 days, all was running fine. Went to dinner Sat night and all was great, left the restaurant and as soon as I started the engine I noticed a slight vibration. As soon as I hit 42 miles per hour, it started shaking pretty good. I pulled over and checked under the truck to make sure I did not have anything I was not supposed to hanging down.
Driveshaft looked good, nothing leaking from rear end or tranny. When it does vibrate, the Tach shows the unhappiness as well. This a.m. driving to work it was vibrating at all speeds and shifting was very rough, had a hard time deciding if it wanted to be in second or third gear. I don't think this is drive train issue... When it shutters and sputters at 40ish MPH, its almost like it loses power and I have to let off the gas. and then under power it shakes badly.
I had the super chip settings for performance tow when this started and then I changed it back to stock settings, thinking it might work, which it only got worse. Changing the settings with the Superchip you have to disable the fuel system and I do this by pulling the fuel pump fuse under the hood in the power distro box.
I think the ujoints are still good, the oil and tranny fluid are spot on. Hubs are locked but in 2WD. Had all the front end replaced 15K miles ago. Brand new tires and wheels in Sept, front end alignment done at same time, front brakes were 90% and rear brakes at 20%.

When decelerating from 40-50+ mph, I sometimes hear a ticking sound, like a clock winding down. The ticking gets slower and slower and then when I'm around 10 mph, the ticking abruptly stops and I hear and feel a loud/strong clunk.
It doesn't happen every time I decelerate, but it does happen a few times every time I drive it. Once in a while it will happen when slowing down from slower speeds, but only after I've been in stop and go traffic for a while.
I read about the slip joint grease problem, so I tried that, but my problem is still there. It's a manual transmission, 4wd, 5.4L F-250 Super Duty standard cab, long bed.

I'm getting a vibration through the floorboards when I take my foot off the gas at high speeds. It has a low-pitched (like a subwoofer) hum to it. It's amplified when I go over dips and the suspension compresses, but doesn't exist when the car is in neutral.
(2009 LS, AWD, 120k miles, stock tires/wheels)

I have a 05 f250 diesel 6.0 with 173k. Between 35-60 mph it has started a humming sound and when the throttle is released the sound stops. I still have power boost etc. Someone mentioned degas cap, turbo pedestal or turbo pipes cracked.

2002 5.4L... I have a humming noise that comes from my engine and wanted to see if any of yall knew anything about it. I sounds like it's on the other side on the driver side firewall near the brake booster. Once the engine runs for a bit it tends to start then. It'll start to hum then ill tap the gas to get the RPMs up a bit then its gone for couple miles then its right back on.

I've noticed that when I insert the key in my 2013 F250 I hear a humming noise, if I pull the key out it goes away. What is this noise? It seems to do it as long as the key is in, but is quiet enough that you can only hear it when there isn't a lot of back round noise.

I 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.

I have an '06 F-250 that's making a quiet grinding/humming noise from what sounds like the front end. It doesn't seem to be coming from any side in particular, just an omnipresent noise whenever the truck is moving. It's constant with speed, and most noticable between 30-60 KPH.
Truck has about 268,000 KM on it right now, and has been worked pretty hard for whatever that's worth as well.

I have a 2004 ford f250 5.4 and ithe makes a Humming noise only at idle. I have checked the fan clutch. it seems to be good and does not spin freely. I was thinking maybe idle air control valve but the truck idles like normal and does not stall. the sound does go away when squeezing the air hose doing today the IAC but comes back as soon as you let off. can it still be the idle air control valve if idles fine and doesn't stall?

Every time I apply brakes I hear a weird humming noise, as well as no stopping power. Checked fluids and pads and everything is where it should be. I heard abs can cause this but not sure on that. I know my master cylinder has a very small leak but it hasn't lost any fluids of that sort. I'm lost. I don't know where else to look.

I've been noticing a low pitched humming noise coming from what sounds like the passenger side of the engine. it happened only occasionally at first but within a week of first hearing it, it is now almost all the time. here is some specifics...
-the noise always starts about 2 or 3 seconds after starting the engine.
-the pitch or loudness does not change with increased rpms or with truck in gear driving.
-the noise randomly stops for no given reason whether driving or idling then starts back up again.
-there are no performance issues while making noise, no dip in rpms, nothing. still runs the same
I've listened with the hood up and cant identify where the noise is coming from. is this something i need to get fixed asap or no? I've got a 2001 f250 5.4 with a manual tranny ....

So I just developed a slight vibration in the steering wheel and the floor last week. It happens when I drive with my foot barely on the gas or coasting. If I punch it, the vibration goes away. Also, if I punch it from a stop and take my foot off the pedal I can hear a knock as the car lurches starting to decelerate and its only one knock. I thought it might be the driver side strut bushing because I recently replaced the passenger side but not the driver. So today I replaced the driver but that did not solve the problem. I have fairly new tires all around. I am not sure if it is tie rods or cv joints. All my boots on the cvs look good. What to check. Oh maybe also motor/trans mounts???

Today I noticed that our 5R110 was delaying slightly when shifting from drive to reverse. It was probably about a 1-2 second delay but it replicated itself twice in a row. There was no delay going from reverse to drive. It is just an engagement delay. We are running a Superchips Heavy Tow tune on the truck, it is a 2006 6.0 Powerstroke.
