2004 FX4 has a humming sound sort of like mud tires on highway when I accelerate a little or a lot. When I let off the accelerator, it stops. It happens wether the truck is cold or been driving all day. Seems to be when cruising and holding the accelerator at a steady speed. When i let off, it stops. When I press on it, it Humms. It seems to be coming from behind me or directly below me. I was thinking fuel pump?
View 14 Replies2006 F150 Triton 5.4 Motor... It's been over a months journey with fixing this truck....
How it started: had an oil change, a while back, on long drive after, check engine light started flashing as I accelerated up hill so I pulled over and in a while it was ok, but couldn't get on the gas too much, or it would cause that flashy light thing.
So fast forward to now, after driving it with an intermittent miss for a while, was driving it to work and the miss became a shudder, and she stopped going over 30-40, and runs extremely rough.
Steady but loud idle.
Replaced all plugs with motocraft plugs and new coils all around. No change.
Finally hooked it up to a computer and got random misfires, now it's saying
P0174 bank 2 too lean,
But it's bank ONE that's the only side misfiring.
Here are the freeze frame details:
Frame 1 Mod $00
MIL Status Off
Troub Code P0174
Abslt TPS 24.3%
Eng speed 1665
Baro PRS 71 kpa

ok so i noticed recently that there was this humming noise coming the rear right passenger side everytime i accelerated up to 30mph. the noise would get louder the faster i go. i got it checked by a shop and they told me that it had something to do with my wheel bearing. my car is lowered on coil covers and I have negative camber on my wheels. Why its making this humming noise or if its because i never got my alignments. I am thinking of throwing my stock suspension back in and letting the dealership deal with it since my car is still under warranty.
View 14 RepliesI went to throw my truck in 4wd the other day and now I'm experiencing a humming noise, but only when in 4 wheel. It's only noticeable when I'm in 4 wheel and I'm off the accelerator or coming to a stop, soon as I accelerate, come to a stop, or take it out of 4wd the noise disappears.
Only other symptom was I tried putting it in 4-low the other day and all it did for a good minute was rev up a bunch, but I switched it back to 2wd and 4-hi and low worked after that. 4wd does still work just fine, it's just buzzing and it's annoying the heck out of me
I did a search, not just on this forum either, all I keep getting is the old "buzzing 'til I put it in 4wd" topic. Hoping to get an answer before I start dropping money trying to find it on my own. I'm not used to these new-style 4wd systems so I'm lost for knowledge here.
Ok, been trying to track down an odd humming noise on my 08 f150 CC 4x4, 4.6l. kind of sounds like a hub bearing going. starts around 25-30mph and never quites down.
Turning left or right to load each side of the suspension doesn't change tone or intensity of the noise, different pavements doesn't change Tone or intensity. Hubs are tight, CVs are tight, 4x4 works as it should. Cant figure this sound out and it's quite loud.
I have a 2004 F-150 STX 2WD with a 2.5" leveling kit on it. I recently have noticed a rubbing sound that can be felt in the steering wheel and gas pedal the instant you turn right. I just replaced both hub assemblies and I just really don't know what it could be. It doesn't happen when you turn left or go straight and there should be no reason as to why my tires rub, because they haven't before. I got my truck aligned and they checked my joints and everything and said that it was fine....
View 13 RepliesI just bought a truck, it has a whining noise while accelerating, stops while letting on the gas, does not do it in neutral even if i rev up the engine. Only whines while there is some force on it, ie.. accelerating, or going up a hill at any angle, and does it from about 10-15mph- atleast 60mph.
View 2 RepliesI put a link below on the video that I made. But when I come across 1,000 RPMs weather I turn, go straight, left or right it makes this noise like a humming or rubbing noise. I took it to the dealership and they fed me crap saying when it gets worse or when it happens every time brig it back.

I don't think this link is working I'm trying to figure out this iPhone. Search my YouTube channel Kill3rcr3w that's the channel I just uploaded it
A very odd hum from the rear (2005 f150 4.2) that occurs at all speeds. Low speed it occurs regardless of load on the drive line. At higher speeds it only happens when i have considerable load on the drive line. All bearings in the diff were replaced less than a year ago when the main pinion bearing went and the diff gears were in pretty dam good condition. Wheel bearings are not getting warm to indicate a wheel bearing. And when i let off the throttle it hums for a few seconds and dissipates as the tension on the drive line goes away. I even looked at the carrier bearing assy and it seems to be in good working order. I live pretty dam far from any type of service so i was just curious before i start trying to trouble shoot this any further.
View 1 RepliesMy 05 F150 with 107k miles becomes increasingly noisy.... From speeds about 15mph up to 50mph there is a humming noise from the front wheels, clearly audible during coast. It sounds almost like tire noise, low frequency with a clear tone (not rumble) and gets worse in LH turns / better in RH turns. The frequency follows the speed.
I also can feel vibrations in the steering wheel. It's not the tires, I changed them without any impact. Checked wheel bearing play - seems OK. The locking hubs are stuck in locked position, with quite some play between the hub and the driveshaft at the RH front wheel (have not checked the LH front wheel yet), seems weird...
Where should I start to look, - wheel bearings or locking hubs? And more important, we plan a 1500 mls trip to Germany - do I dare to drive the truck? What is the worst thing that could happen if wheel bearing or locking hub?
2008 2wd 4.6L 98K miles F150 for the past few weeks has been humming with a rhythmic vibration which feels like it is coming from driver's side front wheel. It doesn't do it constantly, nor at all speeds. Once I hit about 25mph, you can start to hear a humming. At 35, slight vibration. Between 50-60, heavier vibration. Sometimes at 65+, it subsides quite a bit. Both front rotor assemblies are newer, and I put in a brand new left because I thought it was a bad bearing.
View 5 RepliesI have a 2008 Prius, and I have a couple noises, one of which is related to the airplane noise. I've noticed recently mine starts to make that humming noise in the 50-60mph range (less so at higher or lower speeds). There is 44,000 miles on the car.
View 3 RepliesI have a 2004 Chevy Malibu Maxx with a 3.5 L V6 engine. I bought it new ten years ago and it now has 71,000 miles. In the past year, I noticed that sometimes when I accelerated, the car hesitated for a split second. I assumed a transmission problem was around the corner. I recently had the car serviced and had the spark plugs and wires replaced. It is a 100,000 mile maintenance item but since the car was 10 years old, I decided to get it done. Ever since the plugs were replaced, the hesitation on acceleration problem has gone away. Is it possible that the problem was the spark plugs?
View 5 RepliesMy 2005 Toyota Prius gave me confidence. Here's what happened:
I was driving on the Interstate with the cruise control set at 70 mph. Seeing traffic stopped ahead, I applied the brakes for a moment to slow, then released the brake to coast. Much to my surprise, the cruise control was still engaged and the car accelerated. I applied the brakes again, manually turned off the cruise control, then was able to coast. I drove for another half-hour without incident until the following afternoon when I drove again, experiencing a much more serious problem.
I had just turned left, and was straightening the wheels when I heard, and felt, a loud "snap" in the steering wheel, immediately upon which I knew the steering wheel was disconnected and I could no longer steer the car. Very, very fortunately, and only because I was already nearly stopped, I was able to stop the vehicle without incident.
However, I immediately recognized that, had this happened in almost any other scenario than being nearly parked, the outcome would have been markedly different. The steering wheel is completely loose, not controlling anything, and all the many steering wheel controls are equally disconnected, including the driver's air bag (SRS), something that I would have needed, but wouldn't have worked, had I crashed into oncoming traffic or an Interstate median.
2005 Yesterday the ABS, VSC and (!) lights came on when I accelerated hard out of a right turn and momentarily lost traction from the back tires. In addition, the parking brake light came on and won't go out whether or not the parking brake is engaged. I had the car towed to the dealership, and I"m waiting for them to look at it.
View 2 RepliesEvery 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.
View 2 RepliesI just bought an 04 excursion with the 6.0 diesel. I took a trip to vegas and noticed a humming/ vibration about 55-65mph only in overdrive. i have checked u joints and they look good. The x does have a small lift its the bracket kit with stock springs. What gets me is, I don't notice it driving in town only in overdrive at highway speed.
View 8 RepliesSo here is the deal, as the title states I have a humming/ howling noise in the front end, gets louder when I turn left and quiet when turning right. I have replaced both side hub/bearings, and upon inspection I had a broke quick strut on the right hand side, also replaced that along with sway bar link. I've rotated tires, checked pressure and tread is all good. What this could be.
View 5 RepliesI have noticed a very mild cyclical humming noise at exactly 70 mph. Initially I thought it was the original Bridgestones but it continued after I had a new set of Michelin PSS mounted. The noise can only be heard if the car is on a smooth road and the radio and AC are off. I was wondering if it may be a wheel bearing or issue with the differential. Not sure. Its not a big deal but would like to get to the bottom of it if possible.
View 13 RepliesI have a 2008 touareg 2 V8. When we first got the truck everything was fine.. In the last month or so the driver's side mirror seems to be humming or buzzing at 50-70mph (80-120km/h)... If I fold the mirrors it goes away... Cross wind will make it louder, also it is intermittent... Maybe it's resonance?
View 3 RepliesOk so this has been driving me nuts now for a couple days. When I listen to the reg radio, not noticeable. When i use xm, I switch channels and there is a very noticeable humming noise. Now the louder i turn the volume up the louder the humming gets. It makes the stations sound horrible. Not the same in FM! If i turn the car off the humming noise stays until the radio completely powers off. Everything is stock, stock NAV unit, stock speakers, no add on's. What am i missing before i go chasing gremlins. Some say its the amp, some says its the nav unit. How can i narrow down what it is?
