Ford Super Duty (1999-2016) :: Single Clunk Sound On Occasion When Accelerating From A Stop Sign?
Jun 7, 2014
2012 f250 SC xl 6.2 - Is it normal to hear a single clunk sound on occasion when accelerating from a stop sign? Doesn't happen all the time mind you and I don't ever remember hearing it in the past.
Now just today, while backing up my driveway, as soon as I started the reverse motion, I heard the same clunk. Sounds like metal to metal and comes from the rear of the truck.
Only 7000 miles on her and I treat her like a baby...anything I should be concerned with?

I have a 99 f350 V10 gas dually dumper. Today while driving I stopped at a stop sign. When I went to continue the transmission seemed to be in neutral, then it caught and I drove through the intersection. It 2-3 seconds later disengaged again. I pulled over. When I attempted to put it in park it grinded. (Bad enough I just turned off the key). I checked the fluid. It was close to full and red. While in park I restarted. Truck started fine. I shifted into drive and nothing. It was like it was in neutral still. I attempted to put in park again and more grinding. Also while in park it does not hold the truck from rolling. After getting towed home I checked the tranny fluid again and it was still looking ok. I drained the transfer case also. The fluid in there was near black an appeared to have a metallic look. Does this problem seem to be just my tc or tranny issues also?

I have a 2002 F350 with the 7.3 diesel. I have had this truck since it had 30K miles on it and it now had 90K miles. It has been trouble free minus new pads and batteries. I recently changed the fuel filter and used a Donaldson filter. In the last week while driving the truck just mysteriously shuts off when I slow down for a stop sign. The only lights on the dash is the red battery light, and it fires right back up. I believe it has the original CPS in it as I have never changed it. Do you think this is the CPS going out or something else? I was wondering if the Donaldson fuel filter has anything to do with it?

So my '99 F350 4x4 is making a clunking sound and there is a distinct jolt in the truck while this is occurring.
Symptoms: From a stop while accelerating, there is a distinct jolt and clunk. The best way I can describe the feeling is like something isn't tightened down all the way so there is a split second while inertia is generated and the "looseness" catches up to the acceleration.
When stopping, the clunk and jolt is generated when the truck comes to a complete stop. When the truck rebounds backwards a bit because of the suspension pulls it backwards after stopping, you will hear the clunk again.
I replaced the ball joints a week ago an a wheel hub bearing on the right side. I don't recall this before these repairs, but it may have been making this noise. I was more focused on the grinding from the wheel bearing so I may not have noticed the clunk and jolt then.
Where I should start looking for the problem?

I need to solve tranny problem, it started out a while back, would not shift back into drive after stopping at stop sign (after driving fine for about 20 miles) thought maybe dirty filter so did fluid and filter change seemed to work for a while then started again noticed it was mostly after using cruise control, but u joints were very bad, so replaced 2 of the 3 and worked fine for about a thousand highway miles, then got really bad. Now when I check the tranny fluid cold and /or hot it is way up on the dipstick. Took to ford dealer in ladoga, lied and said no speed sensor codes, but list on the paper he gave me had all kinds of abs and a p500 code.

Ok so I'm having a problem that seems to have been getting worse. 1999 7.3, auto, 4 door, long bed, 6" lift. When I got the truck a while back I had a slight problem where if I was accelerating hard I would hear a clunk when it shifted into 3rd gear. I'm not hard on the truck that often so it took me a while to realize that the noise was the driveshaft hitting the floorboard right at the joint at the transfer case output.
The carrier bearing was flopping around a bit so I replaced that first. No better... kept driving the truck since it was only a problem while being really hard on it. But it's gotten worse so now when I tow (usually not more than 7-8k lbs) I have a bad vibration on takeoff at low speed. If I try to take off from a stop very hard with any load the driveshaft jumps into the floorboard. So I just replaced the transmission mount and checked the motor mounts, no better. Only thing I can figure at this point is axle wrap...?

I have a 2002 F-250 7.3 Powerstroke 4x4. My truck has developed a "clunk" for lack of a better term when accelerating from a dead stop. It is not a shudder as it only happens once within a few seconds of depressing the accelerator and then goes away until the next time I stop moving.
It feels like either something in the drivetrain is not engaging right away, or something is releasing, like a stuck caliper or something. From the way it feels and what I've read so far about the TC/Trans, I'm assuming it is something worn in the drive-shaft/rear diff.
But it needs brakes badly (already have all new rotors & pads ready to install) so maybe a caliper is sticking when depressed and then popping loose under initial acceleration? I think this is unlikely but possible.

Have an 06 F250. When I slow down to make a turn then accelerate it's like the drive shaft spins half a turn before it catches. Been doing it for awhile now. Now I'm get a clunk when I come to a complete stop. When you stop then truck settles there is a little clunk. Does this sound like the slip yoke problem?

F250 5.4L have had a new fuel pump installed and new spark plugs (one blew out). When accelerating, or at a stop i get a kinda hesitation. It did it when I first bought the truck but put correct size tires on it and it went away. What it may be? I don't have a check engine light or anything and at cruise speed no problem--it's just when a slight load is put on the engine?

I have a 2001 f-250 that has dome lights that work on occasion. Mostly don't work. The inside dash dimmer won't turn them on. And they will sometimes work with the rear doors opening. Not the front(4 doors). The cargo light comes on all the time. So I don't know where to start chasing.

Every once in a while, while driving my 06 350 SRW at slow speeds, I hear a grinding noise coming from the left side of the truck. It is almost like a winding grinding noise if that makes sense. It will grind slow to a stop, and then I hear a clunk.
This is a very intermittent problem. The tires are completely shot on the truck, and I thought that would be it, but considering it is intermittent and the clunk I hear as I come to a stop I figured it could be it.

I had a pretty good clunk going on and found the passenger tie rod was shot. The rest of the steer components looked fine. Fixed it and still get a nice bunch of clunks. Went over the steering again with someone rotating the wheel and didn't notice any crazy movements. The drag link twisted a bit but the joints looked solid compared to the tie rod which was completely shot.
So I decided to dig into it today. Looked again and nothing. So I took it into my back yard to drive over some humps left from stump grinding. Clunk, clunk, clunk. I stuck my head out the window and wouldn't you know it the sound seems to be coming from the rear! Took a pry bar to parts like the sway bar links, shocks, etc.... can't detect anything. Maybe a u-joint? Gotta dig in I guess.
Also my rear springs creak like nothing I've ever heard. Dirt roads it's just creak, creak, creak.

My 2002 F-150 with the 5.4 has an issue with a high rev (1000 RPM for a few seconds) while at a stop sign, along with a clunking/banging sound coming from under the truck. This is when I have the brake mashed all the way, and this all happens at the same time, almost every time I come to a stop at a stop sign or light. I do have an intake manifold leak, which i have recently determined, but I do not know if the high rev at a stop sign has to do with the manifold leak or to do with the transmission sounding thump I hear. Could this be a torque converter not unlocking, and then suddenly unlocking? Because after the thump sound, the RPM's go down to around 650 from 1000 every time.

My F250 6.4, 3.73 Crew Cab Short bed vibrates when accelerating from a stop with my 5th wheel on. The 5th wheel weighs 12K. It is a medium to high frequency vibration that is felt throughout the entire truck. It continues through the shift into 2nd (TorqueShift Tranny). The harder you accelerate the more you feel it.
It does not occur if truck is unloaded and you accelerate at full throttle. Is this normal or should I get it looked at?

2007 F250 SD Crew Cab Long Bed 4X4 with 6.0. Bulletproofed, leveling springs, 5k firestone airbags, upgraded brakes, new front driveshaft and new universals and carrier bearing on rear u joint.
The issue: When accelerating from a stop or a slow rolling start, turning right or left, I get a shimmy (vibration) that seems to be coming from under my feet. Not a violent shimmy, but enough to make me certain that something is loose or out of alignment in the drivetrain. IT IS NOT THE REAR END as friends have constantly told me. Rear end was serviced and cluth packs lubricated with no change in issue.
What I've done: Changed transfer case fluid, new front driveshaft, new u joints and carrier bearing on rear driveshaft. There has been no improvement after these repairs, if anything the vibration is a little worse and easier to induce.
I've been chasing this problem for over a year. Going to be pulling a Toy Hauler out west this falls and really need to repair this for my piece of mind..

I continuously read that people with 6.2 F250s averaging 13 mpg or so in a combination city/highway driving. This 2014 4x4 barely has enough power to move itself (honestly, I'd rather have my Ram 1500 back) and barely gets 10mpg. Basically have to give it about half-pedal to even get up to freeway speed and floor it if i want to pass anything. Is it just that much of a POS or does this not sound right? Other than a massive "clunk" sound when shifting from reverse to drive or vice versa, no indication of any problems.

Have a Whistling or hissing sound while accelerating? My 2015 6.2 seems to make this sound while under load. I took to dealer and they claim its the throttle plates not closing all the way. Claims this is normal, but to me it is annoying. Just would like to know what others think.

Picked up a new to me 2011 F250 Lariat. She had a few odds and ends to take care of, but I was ok with that. So far I fixed the reverse sensors (2 were out) creaking in the back (leaf spring bushings needed a little Lithium Grease) Squeak in the back (tailgate step needed a little greasing). Now on to my next problem!
This is my first 6.2l (first f250 in general). Truck starts up great and idles quite. Taking off driving, it sounds loud as hell under the hood. To me it sounds like the Fan is making a loud sound as the motor is accelerating. It is more noticeable when you really floor it. Prior to this I owned a 2010 F150 and I know stomping on it the motor really revs up, but this other sound to me isn't right/normal. Googling around, the closest I found to it was:
Loud "Air" Sound Upon Accelerating 2002 FORD EXPEDITION - fan clutch! - YouTube
Granted it's for an expedition, but the sound is damn near identical. Looking on youtube at 1 or 2 videos of a f250 doing a 0-60 all I heard was the sound of the motor revving, so that has me convinced the sound I'm hearing is not normal. I'm 99% convinced it has to be the fan clutch.

1999 to 2002 F-250 ... As the title says, looking for accurate weight difference between single cab and xtra cab.
Looking for replies from those that have knowledge from trucks that have actually been weighed, not just speculation.

So I'm interested in putting a new steering stabilizer on my truck and am pretty set on the Rancho RS7000 series, but I am torn between getting a single OEM replacement or the full dual stabilizer kit. Single replacement? Did it make a difference? I've heard really good things about the dual kit, but obviously the price difference is huge. I don't do a ton of off-roading, but I do drive constantly on crappy city roads which can be just as bad

I found a wracked 2000 f350 v10 4wd dually with 4.10 and I was wondering if I could convert it to single and swap that to my 05 v10 4wd Excursion upgrades to dana60 for 40's.... Is it possible?
