Ford Super Duty (1999-2016) :: 2007 F350 - Whistle On Acceleration


Mar 25, 2014

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.

Ford Super Duty (1999-2016) :: 1999 F350 V10 - Loss Of Power / No Acceleration Over 2500 RPMs

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.

Ford Super Duty (1999-2016) :: 2015 F350 - Hesitates Momentarily On Acceleration?

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?

Ford Super Duty (1999-2016) :: 2006 F350 - Serious Grinding Noise During Acceleration

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.

Ford Super Duty (1999-2016) :: 2000 F350 7.3 2wd Dually - A/C On Hard Acceleration Only

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.

Ford Super Duty (1999-2016) :: 2003 F350 - Revs Fine But No Acceleration

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.

Ford Super Duty (1999-2016) :: 2006 F350 Shuts Down While Driving After Hard Acceleration

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.

Ford Super Duty (1999-2016) :: 2003 F350 - Low Power / Screech From Turbo On Acceleration And Declaration

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.

Ford Super Duty (1999-2016) :: 2007 F350 Pulsates When Hit Brakes

On my 2007 f350 when I hit my brakes it pulsates... So I put new rotors and brakes up front.. The pins are good and the calibers are good... put it all back together and still the same thing... the slower you go the slower the pulsating gets... And I can actually feel the pedal move in and out when it does it... I'm lost....

Ford Super Duty (1999-2016) :: 2007 F350 6.0L Cranks But No Start

2007 6.0l cranks but no start. Read all the forums and I think I performed all the checks. Getting a ficm/ cam sensor/crank sensor no sync. I'm also getting 84.70% at the ipr while cranking. Do I have multiple problems? Watched videos on either the ficm or ipr percentage but not one that had both problems. Getting injector clatter and fuel pump runs. Didn't see anything obvious with the harness.

Ford Super Duty (1999-2016) :: 2007 F350 XLT - Front Brakes Not Working

I have a 2007 F350 XLT, Super Cab, chassis cab, V-10, 4x4. I ordered it new, it now has 97,000 miles. It is equipped with a 9' aluminum flatbed. I tow it behind my motorhome and also carry a truck camper (not when towing it!).

I don't think the front brakes are working 100%. I have 2 sets of wheels and tires (19.5s for hauling the camper). Every time I change over, I check the brake pads for wear. Over the first 80,000 miles there was very little wear on the rear pads. In 2014 I had almost a complete brake failure while traveling. I took it to a Ford dealer, and they determined the brake booster was bad. They replaced the booster and flushed the brake system. I didn't think the brakes felt right afterward, but I carried on. By 95,000 miles, the rear brakes were worn out. I feel like the rear brakes are doing most of the stopping now, thus wearing out much faster than they were.

I just ordered a set of service manuals for the truck (9.5 years late on that!) hoping to figure out something. I like the truck, it meets my needs, and I hope to keep it quite a while longer. I took it in to the local dealer to replace a leaking rear pinion seal. They found and replaced the worn pads. I trust them to the extent that the pads were worn, as I had already noticed an acceleration in wear. Local dealer that replaced the pads has no idea what could be up. They did clean and lube the front calipers at the same time, but I noticed no difference in brake feel. Stopping power is definitely worse than before the brake failure/ booster replacement.

What might cause this? The only things that come to my mind is a problem with the proportioning valve or maybe the master cylinder. I don't know much about the details of the ABS system. Is there anyway that might be causing the issue? I would rather not just start throwing parts at the problem...

Ford Super Duty (1999-2016) :: 2007 F350 - Steering Play At Highway Speed Only?

I have a 2007 f350 scsb with the 6.0 that has 131k miles on it... I bought it in December at 125k and since I first got it I've noticed a lot of steering play at highway speeds only... Basically 60 mph and up... I have a hard time switching lanes and passing because it's very unpredictable just how the truck will behave... It feels like the steering is loose but also slightly delayed and when I make slight adjustments it feels like the truck overcorrects itself... Could this be a steering box issue? A power steering issue?

Ford Super Duty (1999-2016) :: 2007 F350 - Uplifter Switch Wiring Diagram

I just picked up my 2007 F350 as a replacement for my 2003 F350 (still have the 2003). I really like the uplifter switch option on the truck, I can normally figure things out but I am one of those people who is electrically challenged (home and auto)and also am one who does not wish to butcher the new ride (same for the home)to gain an education in the art of wiring. I would like to reinstall my headache rack lights on this truck as they are needed for winter work. I was in my truck manual and the info for wiring is weak and the website did not respond nor did my email to ford. I have found the wire harness but it is not tagged as a pair/color to switch. I have the lights already grounded to the rack, so I am thinking I just need the hot wire from the switch. Looking for the color code for positive and ground for the switches.

Abs light came back on once I started driving, week ago my right front caliper stuck and got very hot, could that read bad for the rear of the front went bad?

Ford Super Duty (1999-2016) :: 2007 F350 4x4 - Popping Coming Of The Front End Of Truck

I have an 07 350 6.0 was plowing last night toward the end of the night i herd a popping coming off the front end of the truck. My esof does not work so I manually lock the hubs and then turn on the 4x4 from the dash when I want 4x4, ok so after the few pops I heard while slightly turning I straightened out and all seem ok till I pulled outta the parking lot started driving and i had a noise kinda sounded like driving on a flat while at speeds at around 25-35mph so I got out unlocked the hubs drove it and it drives fine unlocked. so what I've done so far is while hubs unlocked climbed under it spun the front driveshaft by hand and spins freely. When the truck is rolling with no issues i locked the hubs left the switch in 2wd turned the wheel and started to make a turn and POP loud and shakes the truck violently it feel likes the steering and the truck is binding when trying to turn.

Ford Super Duty (1999-2016) :: Whistle Coming From Under The Hood

2015 with a 6.2 and 1200 miles. I have a whistle coming from under the hood. I didn't here it at first with the windows up and AC on but now that its cooler I have the windows open. I only here it at 2000 RPM or under while accelerating. Doesn't seem to matter how hard I am on the pedal or how heavy the load.

Dealer is going to have to fix it but would like to get a heads up for what it could be.
