Ford Super Duty (1999-2016) :: 2006 F350 - Serious Grinding Noise During Acceleration
Apr 27, 2016
My 2006 F350 is giving me grey hairs. I'm trying to figure out what's going on with it. I have been getting an occasional (more often than not) grinding noise from what seems to be the front of my truck. It will do it from a stop, under light, moderate, or heavy acceleration. Doesn't matter. If I let off the throttle momentarily it will stop until it shifts and will grind again through all shift points it seems.
Logic says it's got to be the wheel bearings or locking hubs. I recently did both on both sides to no relief. Because this is an 06 it had a different hub set up then the previous years which I've read a lot of info about (needle bearings). It doesn't make a lick of difference if hubs are locked or on auto. If in 4x4 (ESOF) or 2wd.
As mentioned I replaced both wheel bearings with FORD parts and both locking hubs From FORD as well. (Small fortune). Axle u joints seemed tight. Greased me up but no play.

My 1999 Ford F350 Dually 4x4 started making a grinding noise every once in a while about 3 weeks ago. Now it is doing it quite often, randomly as I am driving. I do notice the noise stops when I stop the truck, or when I flip the switch to 4x4 and back while driving.

I have an 06' f350 6Ltr. Over 300 k. Good shape, i have owned it for about a year. My first diesel. Last week it wouldnt start, had a 1/4 tank. Read about problems with other trucks with a broken pick up on fuel pump. So i filled the tank and it started. Next morning used command start and it ran for 1 minute then shutdown. took about 5 minutes of manually turning it over and it fires up ran all day. Does this almost everyday since and now shuts down while driving after hard acceleration and surges under acceleration when on incline or underload. Changed fuel relay, fuel filters. Researched and asked around but getting mixed opinions. I am mechanically inclined but this is a little beyond my scope of trouble shooting and id rather not start throwing parts at it.

Have an f350 4x4 diesel that when I drive slow and especially turn to the right it makes a grinding noise. It seems to either go away or just gets muffled by road noise when cruising. The ball joints were bad so I replaced them and I figured with this especially when I turn right it had to be a wheel bearing so I replaced both of them and still same thing. Don't want to throw money at it hoping to fix the issue. Also front duff is full of oil.

i have a 2006 F250 XLT 5.4L 4x4 Crew Cab. after months of dealing with an ongoing power steering issue and replacing pumps left and right, i decided to replace the entire power steering system. Ordered Gearbox, Pump and Cooler from dealership. The install went fairly easy, and finished in 2 days.
The truck used to whine and grind as i would turn wheel any direction, driving or in park and the wheel used to pull , like jerk a bit when i would go like in a u-turn.
Not anymore, all those issues are gone. Steers straight , no whining , wheel doesn't pull anymore and all seems fine, EXCEPT when i take a turn , for example onto a driveway where its a bit of an incline. Then, i hear some grinding noise and a bit of vibration in my wheel. I think it comes from gearbox or pump.
Im scared not to drive it too much as all is new components and don't want to ruin all over again.

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 only hear it at low speeds, but I guess that's to be expected. I've heard a similar noise before with other cars/trucks, but I can't recall what causes it. Just looking on tips for where to start looking with the front end parts or wheel/caliper assembly.
Also, but not sure it's related, had a lot of front end wobble when I applied the brakes coming down steep hills last week while pulling a big, but empty, gooseneck trailer. I assumed warped rotors, but later, after I had picked up my load, it quit doing it, albeit I had started babying the brakes. Still, there was one instance of very hard braking and it didn't do it at all, but that was on straight pavement.
It's almost as if having that empty trailer and/or going down a steep hill caused it, and not anything on the truck. But the rubbing sound started before that wobbling. Whatcha think?

2007 F-350 4X4 King Ranch... I have the 6.0 diesel. I am on the road to Houston, Tilden and San Antonio TX, and I am noticing a whistle on acceleration. I can change the tone by how hard I push down on the accelerator. I thought it was a radio issue and turned the radio off and got no change. Turned the a/c off, no change. Down hill or coasting, nothing.

2001 f250 7.3 crew
So, Saturday my abs lite comes on. Later that day I hear metal to metal sound for a couple of secs then it stops. Then the next day while driving I get intermittent sounds that sound like I'm dragging metal down the pavement. I see nothing but I'm thinking hub bearing. (Needle)
I remove the hub assembly from the knuckle and can find nothing wrong. I even picked up a new hub just on case. Now I'm stumped. Can't figure out what the sound was or is. Axle has a little play going into the housing but figure it would have due to the only thing holding it in place is the hub.
The only thing left in the area that could make the sound is major --the actual gears to to the front end. If the bearing isn't causing the metal grinding sound I've no other idea other than that....

Truck sat for 1 1/2 years. Changed filter and put in 15 gallons of fuel. Had maybe 1/2 gallon old fuel in tank. MAYBE. Fixed fuel line because it wasnt getting fuel and it fired right up and idles great.
Truck has no acceleration over 2500 (or so) RPMs but idles fine. This is depending on how hard you push the pedal of course.
If you drive the truck normally like a grandmother it seems to be ok. As long as you dont need a passing gear or need to accelerate more than 1/4 pedal
If you try to push the pedal to get the next higher gear it will sometimes hit the gear fine. IF you floor the truck it will totally lose acceleration. Then the truck will run like crap even slow for a good while. But then it will clear up for the low end. Then you can drive it normally. Then when I think I can test the upper end I get the same thing again.

2015 F-350 diesel purchased in Sept 2014. When moving slowly such as turning a corner and I have to let up on the accelerator momentarily, when I press down again there is nothing for an unsettling period of time, maybe 2 seconds, as though the engine died, but it didn't and it always comes back. Is there a firmware programming update for this?

I have a 2000 F350 7.3 2wd Dually - that only only produces cold air conditioing on hard acceleration only stays on for a few minutes then falls away.
The temperature is cold when its going. I've checked the levels and its gased OK. There is no voltage to the clutch on the compressor when it is not working. So I take it, that it isn't the clutch shim/spacing.
If I accelerate hard it comes back immediately. Whether I am going slow at 1500rpm or doing 70mph at 2500rpm - Uphill or downhill. Its seems to need a substantial amount of Turbo boost for just a few seconds to turn on.
I actually bled the system a little and its made it worse. Stays on for a shorter time and isn't as cold. However the low pressure side is still on the high side at 50psi when running.
Its done this for approx 2 years and its getting worse.. And now its really hot outside.

2003 F350 5.4, 4R100 trans.... I've had this truck parked for a few years but want to get it into service for farm use.
In park or neutral, it revs great, idles a bit rough but not terrible. But in drive under load it I can't get it above 1500rpm most times unless going downhill, and then it shifts very late, and I have to get it up to 3500rpm and then let the throttle off to get it to shift. It does better in 4Lo with shifting, but it's still very sluggish.
Now it says to check fluid level in Park at idle. When I do this, I just get fluid on one side of the dipstick, not a full dip as you'd see on an oil dipstick. And the wet on the fluid goes up past the hash marks quite a bit. I'm use to seeing the dipstick get oil all the way across, and then a bit higher just up the edges, but have always read it at the full cover point.
I suspect low fluid, but I'm not really sure with the way the stick reads. I was thinking of draining it all and then filling to spec as per: [URL] .... but have a long drive to go get MerconV.

The issue is with my 2000 F350 crew longbed V10. Other than a BTS trans put in a little over a year ago, and FoMoCo motorsports headers, the whole truck is bone stock. Oh, it has that fantastic auto-hub thing with the fake locking hubs and the little switch on the dash (I'd love to convert it to a manual shifter...?). 174k on chassis, so things need to be done, 40k on engine, 3k on BTS 4r100.
Yesterday I was running around town, made a stop, and when I started moving again got a loud grinding from the front axle. Thought maybe I'd picked up a rock in a caliper or something, so I jumped out and checked everything, no joy. Moved forward, there it is again. No vibration, but loud enough (or telegraphing enough) to hear clearly in the cab. Let the truck roll forward, popped in to neutral, noise fades away. Back in to drive, there it is. So, now I know it's trans/t-case/driveshaft/related. I recently put new vacuum lines in, checked all the connections, and pulled, cleaned and lubed the hubs.
And since the trans is a nearly new BTS that is working just find, I'm narrowing the search to the hubs, drive shaft, t-case.
Get home (noise abates above 30mph, or everything else drowns it out), crawl under, and find the front driveshaft is locked. Ok, stuck hub? Pull out both the fake locking hubs, and now the shaft turns. I can turn each front axle by hand at the u-joint, and I kinda hear a faint grinding on the right side (will bad needles make noise only under a load from the trans and not coasting in neutral?), and when I swing the drive shaft around the left axle moves, right doesn't, etc etc.
I'm going to pull the drive shaft today and check the U joints, and drive a bit to see if the noise is still there, but I am thinking I might have some bad needles on the pax side axle...

My buddy's 2001 7.3L F350 has had 3 transmissions. Rebuilt and used. Once the new trans is in he goes like 15 miles and then is starts shifting hard and grinding gears. What this could be?

I have this bucking a jerking when pulling my Sundowner LQ horse trailer, primarily in the 40-50 mph range. I can let off throttle and it stops but resumes unless I feather the throttle.... 2008 f 350, 4WD, 6.4, 48k miles....

2003 6.0 F350... Under full throttle from take off goes about 20 mph just revs at 2500 let off the throttle in feather it shifts and acts like it wants to go just not allot of power sometimes. In neutral won't rev past 2700 rpms I do hear a screech from the turbo on acceleration and declaration. Also if in tow haul the truck won't shift at all. I can get it up to speed but even the smallest incline drops to 50 mph then takes bout 2 miles to get it back up to 65 mph or if I go downhill.... turbo makes the noise the whole time sometimes goes into passing gear in have to let off in it kinda my the truck hop in this is at 60 +mph. Only thing I have really tired was fuel filters and checked at plugs and boots.

1999 f250 super Duty V10... I am having some problems with switching out of four wheel drive. S, when I flip the switch back to 2 wheel drive everything, seems ok at first, but within a mile or two I will hear this grinding coming from the front that sounds like the gears aren't completely disengaging. The inky thing that prevents this grinding from happening is switching back into fire wheel drive and keeping it there. What might be causing it to not stay disengaged ?
