Ford Super Duty (1999-2016) :: Truck Will Start To Buck / Jitter At About 60 - 70 MPH
I have a 2006PSD 6.0. At about 60-70mph my truck will start to buck/jitter if i give about 5-10 percent throttle. It only happens at these speeds and i tried all sorts of fixes so far. Also there are no codes. Truck starts and idles great. At more than 10 percent throttle at 60mph, it acts normal. My current fix is just drive normally at 80mph. I also see talks about the possibility of the Turbo vanes being stuck, but wouldn't that happen at other speeds also?

Ford Super Duty (1999-2016) :: 2007 F250 - Steering Gear / Suddenly Developed About A Quarter To A Half Turn Of Slop
My 07 has developed a steering gear issue.....it suddenly developed about a quarter to a half turn of slop......mechanic checked the front end and found everything to be tight and right so......I ordered a Redhead rebuilt box and will replace it upon it's arrival. My question is How often do these boxes go bad and if and when they do is it at all safe to drive the vehicle with that much play? I have to drive it about 15 miles to get to my mechanic ( far too cold for me to do it at home) and I also plow a couple of yards commercially and will need to use it there in the event of a snow storm.

I have a 2015 SD with only 4100 miles on it. This has happened to me twice. Both times, traveling slowly at idle or just above. Anyway, tried to give it a little gas, and -----nothing. Lightly pumped the throttle a couple of quick times and back on line. The motor didn't die, but there was no response to the throttle at all. The first time, I thought maybe it was something I did. Then it doesn't happen for a month and a half and then again, in heavy traffic in the rain. Haven't had my first service yet, and you can bet I'll tell them about it. Almost felt like a two-stroke that had loaded up?

So I have a 2016 6.7L love it but it has this vibration at 65 mph that is worse when accelerating up a hill. It feels like an out of balance wheel but I have had them balanced 3 times. road forced 2 times. My dealer replaced the driveline also. I did a test with 400 lbs of concrete bags in the bed and it was vibration free. It almost is like the pinion angle is off.

View 2 RepliesFord Super Duty (1999-2016) :: Clunk While Accelerating And Braking
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?
Ford Super Duty (1999-2016) :: Shaking When Accelerating Or Braking From About 40 - 60 MPH
Truck is a stock 2001 f250 7.3 with 205,000 miles. When accelerating or braking from about 40-60mph it starts to shake a little bit. When braking it shakes a lot more from 60 down to 40. But the faster you speed up the less it shakes when taking off. Looked at everything underneath is tight, and it has stock a stock steering stabilizer. Would a new stabilizer fix this you think?

I have an issue with my 6.0 that no one can figure out. It has been happening for about 3 years. After accelerating hard, motor will rev out like it just popped out of gear. It is still in drive and the edge cts says 4th gear usually. I have to let off the pedal and coast a bit and everything "sync's" up again and works fine. It can happen from a hard launch from a light or get on the freeway. I recently put an ATS transmission in because I figured solenoids were beginning to fail. Still does it. I am running innovative tunes with sct tuner. It had a Suncoast billet flex plate and ATS 5 star converter. I run Amsoil fluid, it is clean, red, and at the proper level. Truck has almost 80k miles. Also 37" tires and 4.88 gears. It has not done it while towing our 35' toyhauler, but I am easy on the pedal when I tow. I recently checked the transfer case and changed fluid to Amsoil. The old fluid looked good.

So lately I have noticed that my 99 F-250 has a bit of a "bump" while accelerating. Think of it as accelerating with a trailer and something is loose on the hitch, making a sort of bump or thump. I talked to the guy at the parts store and he said to put it in neutral and wiggle the driveshaft up and down, side to side.
When I did that it moved up and down, but not side to side, but I'm not sure if that's because it's just positioned that way or what. The wobble was coming from the slip yoke back by the rear diff. Is this something I should be concerned about? Also, I have an ext. cab and short box, 1 piece driveshaft.
Here's a video (a very crappy video at that), not sure if it gets enough info through or not but hopefully you kinda get how much play is in there.
Ford Super Duty (1999-2016) :: Transmission Whine While Accelerating
The truck is a 2012 f250 6.2 flex fuel from alberta canada. This isn't the first tranny form out there that I've heard do this. Tranny seems fine shifts all right just a whine while accelerating.
View 7 RepliesFord Super Duty (1999-2016) :: Hesitation When Accelerating Or At A Stop
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?

This has just started this past weekend out of no where.I went to accelerate up a hill and when it got to around 2500 rpms it just starts acting like a rev limiter kicks in.When i let off throttle it smooths out and runs fine, seems anytime its past quarter throttle it doesnt not want to move anywhere.If you drive normal in city conditions or on a nice flat round with barely any throttle it runs fine.I replaced the fuel filter no change, removed air filter no difference.Its actually at the shop now and they say its a transmission problem, my opinion i disagree fluid is up, no burning smell, and shifts fine under normal (slow) driving. 2001 Super duty 5.4 triton....

Took delivery of my 2015 F250 in June with 2WD and the 6.2 gas engine. What I thought to be a slow throttle response seems to be more of a quick shifting transmission according to two different dealerships. My 6 speed automatic has already shifted to 4th gear at only 25-30 MPH. My Dodge Hemi I sold never had shifts as quick as this and I think it's to quick. My question is....is there a way to change these shift points so I get more speed before it shifts into the higher gears?

My friend has a F250. He was getting terrible mileage and the mechanic he took it to replaced the intake gaskets. After that the mileage went to 12 and he was happy. Now its down to 6-8, just highway. It seems to me the throttle response is terrible compared to my dad's 01 V10. And it sounds terrible. Exhaust manifolds aren't leaking that I see.
I've got AE and have hooked it up, but I'm really not very familiar with these trucks. I don't get any codes that would relate to anything. Had one trans sensor code but that was about it. Key on engine running test didn't say anything.
