Ford F-150 (2009-2014) :: Buzzing Followed By Grinding Sound
Feb 10, 2017
I have a 09 f150 with 160,000 on it. For the last couple months I was hearing an occasional buzzing sound from the engine compartment. Couldn't duplicate it while not driving. The buzzing sound has changed somewhat but it's follow by a grinding sound that seems like the hubs are trying to lock while in 2 wheel drive. I think the buzzing is coming from either the IWE solenoid or the vacuum check valve. My question is this. If I pull the vacuum line off the the solenoid and plug the line will the hubs remain locked till I can dig into this a little deeper. I was thinking that they would stay locked. I should still be able to shift in and out of 4 wheel drive correct?

2000 Venture short wheelbase 122k miles. Original owner from brand new. Has had fuel pump replaced at 40K, intake manifold replaced and full trans (torque converter inclusive) flush, plugs and wires at 75K. (2005) All fluids checked regularly.
Recent problem. Noticed a "grinding/buzzing" sound when traveling above 25 mph. Sound is commensurate with veh speed (not engine speed). If I turn the wheel ever so slightly to the right, the sound "deepens"/gets louder), and I can feel the buzzing in the steering wheel. When I release from turning right, or turn left, the buzzing greatly decreases (though I still hear it), and I can no longer feel it in the steering wheel. I only feel it when I turn the wheel to the right, even just a few degrees.
My thoughts on the culprit (in no particular order): Wheel bearing, Transaxle/final drive (differential). ???????
Wheel bearings: No work done on front wheels/hubs. I did rotors and brake pads in April 2009 (115K). Visual inspection of all of the under car and front end. Nothing appeared out of the ordinary.
Transaxle/Diffierential: Who knows? I have had other vehicles with a normal differential/rear end, that had a bad bearing and I could usually tell which side, just by driving/turning Usually it was an outer bearing (wheel), not an axle bearing (diff).
Observations:
1..Periodically over the last 2-3 years or so, I have had to add about a 8-12 oz of coolant to the overflow every 8 mos or so. I don't know where it goes. I presume it is evaporating somewhere or VERY slowly leaking. Nothing external that can be visually noticed.
2.. Last week I checked the trans fluid. Was off the stick. Had to add 3 qts Dexron VI to bring it to full mark on stick. First two qts. barely registered on the stick. Prior to that last check was at 118k (5 k ago) and June of 2009. My written notes at the time mention "Normal. Didn't smell or look burnt, and no particulate matter in the fluid". Has been a week and the fluid level is still holding fine. Where did the 3 quarts go ???
3.. Opened radiator cap. No sludge or "strawberry milkshake" evidence of trans fluid. Looks fairly clear and orange. About what I would expect for a veh of this age and mileage. All lines to and from trans and radiator look ok. No evidence of leaking ANYWHERE.
4.. Runs an normal temps throughout the year
5.. Shifts fine with no slipping, clunking, grinding (during shifting).
6.. Overall vehicle runs, shifts, handles, and stops well.
7.. Every few weeks the ABS light comes on and then goes out after the next start.
If it's a wheel bearing (and I am leaning that way) How can I determine which side I need to replace? If I turn right, I "load" the left one. Noise gets louder. If I turn left, I "load" the right one. Given the above symptoms should I presume the left one?

In the past few days, our car (2006 Prius) has begun making some louder-than-normal noises while driving. I've determined that the noise appears when you turn the wheel at all to the right (note: not just making a right turn...any degree to the right past straight is enough). It seems to be constant when the car is running, but really only becomes perceptible around 30 mph. The sound is sort of like a buzzing. Maybe a grinding, but not quite. It sounds like it might be similar to this issue (2006 Engine Noise - buzzing, especially loud on highway | PriusChat), but I can't quite be sure.

2010 F150 - 5.4L ... I encountered a disturbing chatter/buzzing noise while towing recently. I have not towed a lot with this truck but recently bought a 8.5x18 enclosed car hauler and have towed the trailer about 3000 miles so far. Twice I have experienced a chattering noise from the transmission under very specific conditions. Was traveling on a long flat road at about 70 MPH in 5th gear at about 2100 rpm when it started. If I let off the noise would instantly go away.
If I accelerated and went into 4th the frequency and tone of the chatter would not change with either RPM or speed, however, when I let off it would go away. It is almost impossible to reproduce because it has to be flat. It did once start to chatter in 4th when I was pushing a strong headwind at about 70 MPH and 3000 RPM.

I have a 2010 XLT, 85K, just started having a horrible grinding noise at start up for about 2-3 seconds, then gone. Going to dealer tmrrw. Multiple people said, possible oil pump hydraulics, ??????. Whatever it is, they say its expensive!!!!!

I have a 2011 F150 ecoboost supercrew 6.5 ft bed. I have noticed a bad vibration/ grinding in the driveline, mainly after a long trip on the highway and coming to a stop and starting again. And it's noticeable at lower speeds. What this may be caused by. It seems like the rear end is binding but I have had the rear end checked and the level was good.

There is a grinding noise when i make a turn,when i straighten out it's fine,when i bought the truck in 09 i had a shudder problem but that was repaired by greasing the spline in the drive shaft. Truck has 59,000 and is coming up on the 60,000....

Recently had a coworker point out that my truck was making funny noises while it was backing up. It is a 2013 f150. It almost sounds like metal grinding to me. It does not do it while going forward either.
Have been underneath and can't notice anything out of place, although I'm not sure I'd notice if there was.

Just got a 2010 lariat supercrew...I put 1900 miles on it so far. When slowly letting off the accelerator (doing between 20-30 mph and between 1000-1500 rpm) there is a distinct rubbing sound for about 1-2 seconds...it is now sounding more like grinding now...took it to the shop today...(they couldn't duplicate (because service rep documented 60 mph instead of the 20-30 mph...went back at the end of the day to ride with the tech, and i was able to duplicate so now they have something to work with....also the noise happens mostly when the path of travel is either level road or slight to great incline..it has not happened on a down slope....

I've owned this 2012 Lariat 5.0 for about 6 months (has 49,500 miles on it, approx 6000 are mine).
For awhile, I had kinda thought I sensed a slight vibration/grinding when making right-hand turns. But it seems to be getting more noticeable now. It does not happen with every RH turn, but its not all that rare of an occurrence either. (Does NOT happen with LH turns.)
In addition ............ possibly related, sometimes while breaking, I get a somewhat similar grinding sensation, just before coming to a stop. Again, it does not happen every time.
I tend to think both of these could be a brake issue, but wondered if anything in the driveline could be contributing ? (I should note that I'm in 2-High)

2013 Platinum. See sig for details. 37,000 miles. 1 owner. Truck has been basically parked since June. However I take it out for a quick spin every 3 week for 10 miles or so. Currently has storage insurance on it.
When backing out of the garage the brakes are grinding and squealing bad. Also getting feedback through the steering wheel for the first couple miles which leads me to believe it's one or both the front brakes.

I have a 2013 XLT Scab that has been in twice now for a low speed to stop brake rubbing or grinding noise. The first visit they turned the front rotors and scuffed the pads, which seemed t fix the problem for about a month. The second visit they repeated the same process on the rear and the problem was good for about two months. Today while driving I noticed the noise, probably worse than I have ever heard. It seems like after about 20 stops the noise gets quieter. I am taking it back for the third time and I am hoping they will fix the problem for real this time. I am tired of burning my gas to get to the dealer and then having to ask my salesman for a loaner car. Other than this issue I love the truck.

Wife's 2010 F150 4x4 85000 KMs makes grinding / ratcheting noise in LH front axle when in 2 wheel drive. Mostly when turning left some times when traveling straight never when turning right. Never makes the noise when in four wheel drive. I am suspecting the auto hub is the issue but wonder if others have had this trouble ?

First off I have a 2009 F150 4wd 4.6L truck...we have noticed a grinding noise on the front driver side wheel...we have replaced the auto locking hub acuator and the hub assembly but the noise is still there....it has us puzzled now not sure what it could be. I have read many different threads on this issue an it seems that it might be something to do with the vacuum. The noise is only on the driver side and only in 2wd, when its in 4wd it doesn't make the noise at all. Also while in 2wd the noise seems to go away when we let off the gas.

Just installed new actuator and wheel hub assembly on my 2009 f150,truck still had grinding noise in front passenger wheel , New solenoid and vacuum hose kit installed when test drove noise still there until you put the truck in 4 wheel drive it disappears . The noise returns as soon as you take it out of 4 wheel drive. Also mechanic said steering was tight,installed new shaft same thing, could this be the rack and pinion.

This morning (roughly freezing temperature - nothing out of the ordinary after the brutal winter we just had) got onto the highway to head to work and set the cruise control (as normal) at approx 110km/h (65mph) and after several seconds heard a distinct, quite unpleasant grinding noise. It was loud enough to be heard over the heater and radio. Turned the heater and radio off to listen closer and didn't like the sound of it - sounded like metal on metal.
There was no different feel in the floor, pedals or steering wheel. As soon as I turned cruise control off, the noise disappeared! Turned cruise control back on, and the noise returned approx 5 seconds later. If I continued driving along normally and sustained a certain speed, the noise would appear after 5 seconds again and only go away once I lifted off the gas or coasted down a hill... Very bizarre. Once I got to work and poked my head underneath didn't immediately notice anything out of the ordinary - no funny smells or anything...
Background info: 2011 FX4 ecoboost, crew cab. Stock, no modifications. Approx 134,000km (~80,000 miles)...

Today I was out getting lunch in my Ecoboost When it started making an extremely loud grinding noise from the front end of the truck. My first thought was I blew a turbo. After holding the break and building boost I discovered it was not the source of the noise. Also the truck runs perfect and there is no smoke. I then took it to my friends auto shop and pulled both front tires off to check and see if anything break related came loose. We found nothing. The noise only happens upon acceleration or cruising throttle, as soon as you let off the sound goes away. So after I found nothing I took it to ford and what would cause that, but they assured me that they would have my truck for a long time while they figure out the issue.

Another issue to my Accent 2009 model, when I switched the key to Ignite, I can hear a low pitch buzzing sound somewhere in the front of driver seat, maybe in the steering wheel column or under the dashboard I don't know. Even when I already started the engine, or even when I am already running slow or fast, the sound is still there. What is that sound?

This evening, my F150 with 2,600 miles developed a high pitched squeal, much like you might experience on an older vehicle with failing front brakes. Yes, that same squeal/grind the brakes make...metal on metal. It came in instantly while at highway speeds. It was VERY loud. The pitch didn't really change with speed...it was pretty consistant going slow or fast. There was no vibration, chatter or growl as I would expect with a failing bearing.
It was definately in the driveline/brakes. I was 10 miles away from a friends house, so I turned around and took it back to his place. Shortly after turning around, it quieted, only sounding when I would turn ( like a wheel bearing would when being side loaded ). I looked at the brake disks, thinking something was grinding on one of them. The outsides of the disks looked fine. Due to the shields on the inside, I couldn't see.
Later in the evening, I had to drive it back home, about 50 miles. Again, it was quiet unless turning fairly hard. By the time I got home, the squeal had turned into an intermitant growl/thump, as if a warped rotor was banging on the caliper. The noise was 1 to 1 with the rotation of the driveline. But still no vibration. Brakes work perfectly and the noise doesn't change with brake use. Backing up and turning hard results in a variety of sounds, including squeaks.
The hubs and CV joints felt cool. The brake disks were not hot as if they were dragging.
It is 4x4 / 3.7l

2011 F150 Limited 4wd 6.2 liter. I just bought the truck a few weeks ago with 26,000 miles. Late last week I began hearing a mild grind/rustling noise that appears to come from the driver's front. It's not terribly loud (loud enough to hear), but it's annoying. It happens when I slow down (on and off the brake and below 25-30 mph) as well as let off and begin to speed up. It doesn't last but a second after I let off the brake and speed up though. The kicker is it does not happen all of the time. I drove it home from work last night and it did not do it one time, but driving to work this morning it happened every time I did what I described above. I have taken it to our local tire/suspension shop and they claim they could not reproduce the sound which does not surprise me. They did a full inspection and found nothing.

I have a 2wd 2011 F150 90K with grinding noise coming from the drivers side front tire. Even though it was happening when coasting I thought it might be pads but they are real good. Turning the hub with no tire on it I can hear a little grinding. So I suspect bearings. I want to remove the hub but can't find out how to pull that off.
Where I would expect to find a spindle nut there is an area where it looks like you put a puller in. Can't find any videos or other information on the "Internets". Maybe I'm the first to have bad bearings? Anyway, how to remove the hub?
