Ford F-150 (2004-2008) :: Driveline Jerking When Try To Accelerate Sometimes On Flats / Rarely On Downhill But Always On Uphill
Sep 26, 2014
2004 F150 FX4 5.4L. I drove from Vancouver to Edmonton and back this week and I started to get some issues. If I'm in overdrive at highway speeds, from about 90km/h to 120km/h give or take, which would be around 1600-2100rpm, and then I try to accelerate, sometimes on flats, rarely on downhills, but always on uphills, the truck will begin to jerk fore and aft. It feels like it's something through the driveline, either the driveshaft or the differential, but I really can't say for certain as I'm stuck in the driver's seat while this is happening.
If the truck downshifts or if I take it out of overdrive, i.e. getting the revs up high, the problem is no more. Other than the issue I'm having, it operates perfectly so this is very odd. I know that overdrive isn't a hill climbing gear, but normally an engine in the wrong gear will simply lug along until it's downshifted. The entire truck jerking shouldn't happen.
On my way to Edmonton, I noticed that this would cause one single, minor jerk. This is my way of describing it, but it was like the driveshaft had spun freely and then promptly re-engaged with the differential gear, causing a clunk. I doubt that's actually what happened, but I'm just trying to explain the sensation. It kind of feels like trailer jerking.
On the way back to Vancouver, it was a lot worse. Like I said, the whole truck would be jerking about once per second but there was one time that I found the sweet spot and it began jerking rapidly, twice per second. I threw it out of overdrive to stop this but the vibration caused the check engine light to flash a few times but it went away and didn't stay on.
What I might be up against? Been doing a little research. Seems as though this is common and it's supposedly the spark plugs, but those only have 50,000km on them.

I've had occasional issues the last year getting my 04 into 4WD, but at 270K on the original IWE actuators, that's probably to be expected.
I had new actuators ready to install, but took the truck out for a drive before doing the job. On a gravel road the back tires spun easily in 2WD, I switched over to 4wd and it was much harder to spin the tires- you could tell it was in 4WD- or at least seemed that way. I left it in 4WD and tried turning on a tar road and it didn't seem like it was binding at all. (I have an open diff in the rear, assume the front is the same?)
Anyway, I installed new actuators last night and took it out for another drive afterwords. I put it in 4WD and could IMMEDIATELY feel the binding when turning.
What I cant figure out is why I could NOT feel binding while in 4WD prior to the install. Could I have been in 3WD somehow? (04 Super Crew, Automatic, 4.6L, XLT- pretty basic pickup...)...

On my 07' I bought it home mid AUG. It has been getting much worse to a point there is a rear driveline vibration at all speeds above 40 and up to 70. I used to change intensity whether you are on or off the gas, and would almost vanish if in neutral. However now it is all the time.
I cannot feel any play on the u-joints, the yoke has a little play in the xfer case but is is normal like on most other trucks I have owned, and the pinion flange is nice and tight. Could this be **tight** ujoints or the driveshaft itself? It looks rusty, but there are no dents on it.

I have a 2008 Honda Odyssey. Lately, we've been bothered by a sweet smell, particularly when coming to a stop at the bottom of a hill or acceleration uphill. The smell is most noticeable from the two front, center AC vents. The dealer swears it's not a hose or heater core issue. He also checked the cabin air filter. AC "on" and recirc "on" seem to exacerbate the problem.

I got my 77 ford truck w/four wheel drive half ton with a np435, 351M and i was wondering if a bad or worn bearing can cause vibration. i can feel it by the pedal when i accelerate from 50 to 65. I don't know if that's my trans or maybe the pilot bearing?

I just bought this car last night from a guy with a dealer license. The car was used, so he sold it with an "as-is" statement. I've read there is a 2 day law to return used cars, but he never gave me this option.
I test drove the car but nothing appeared wrong except the heater did not blow hot, thought the car wasn't warmed up. May be unrelated. Anyways, driving on the interstate I noticed he pulled the battery before selling it to clear the trip memory, and all of that information. So I asked him and he said it was for a small part he installed (he showed me, it looks like a thermostat of some kind with a hose coming off of it, he did not know the name).

I have a late model 2004 F-350 6.0 powerstroke. 182K miles. Auto Transmission
What happened. Condensed version
Left house, drove out to highway, got on highway. Everything feels normal.
About 1 mile of going 70mph, I notice I can no longer accelerate. after 1/2 mile, I begin loosing speed, and engine will not rev past 1000 rpm. I eventually pull over (another mile), put in neutral and will not rev past 1000. put in drive and start to idle to highway exit. it gets about another .5 mile and begin going up a hill when it completely dies. Will not restart.
No prior issues with the truck. Full tank of fuel.
What I have tested so far. Ficm 48.5 volts cranking. Icp .225V KOEO, .875V Cranking. LPOP is registering pressure on the dash. No Fault codes.
I have gotten it to start twice now, one time it allowed me to rev to 750 rpm, where i used 4 low to make it onto a trailer. second time would not rev at all. idling at 250-300 rpm.
That same night as it died, I drained the transmission pan/ TP filter and filled with 8.5 Quarts of Mercon LV. This is the first time I have done this since purchasing @ 161K miles. Everything seemed normal, no leaks present.
Also my buddy showed me how to enter the dash test mode and we cycled through these. Not sure if this is relevant.
So, What do I test next? I don't think its HPOP issue since the ICP is reading .875 volts at crank. I did unplug the ICP and it still would not start. I don't think its the injector side of the ficm because they buzz as normal with koeo, but this is a possibility as I don't have equipment to test. Egr valve is clean for age of truck.
Would it be possible that the Mercon LV knocked crud loose in the transmission causing it to fail/seize? would siezed tranny cause the engine to behave in this manner?
Fuel bowl on top of the engine was full of fuel. I have not pressure tested it yet as I can hear the pump running during key on.
could i have a bad crank or cam sensor?
Multi-injector failure?
Bad Icp with HPO failure?

I have a 2008 2.7 all wheel drive santa fe automaic. It has 110 Kilometers on it. It is stop and go traffic everywhere, terrible roads, and lots of hills. I have actually only owned it for about 14k kilometers.
It has been fine since I bought it a year ago up until about 2 months ago. I was coming to a stop and as I got right to the end of my stop, the car jerked and made a clunk sound. No smell. I could tell it was when the tranny was coming down from 2nd to 1st. I tried to replicate it but got nothing. Ignored it but then it happened again. It seemed more prevalent when I was moving from 1st to second to stop over and over.
As I began to pay attention more and more, it happens much more when going up a hill or down a hill and almost always happens when I am about to make a u-turn and the wheel is turned all the way to the left. When it happens, it isn't always a big jerk. It never happens at speed, the other shifts are fine, and if I shift from reverse to drive too fast and accelerate, I get a clunk as well.

I have a 07 f150 harley edition.. Here's my issue. When I decelerate going down hill. Feels like my rear end wobbles. It will do it if I decelerate and turn the overdrive off or if I put it in 2nd when decelerating and when I accelerate again it goes away..

I'm a new owner to my first 4x4 vehicle. My vehicle is a 2007 f150 xlt. Today while I was driving into work I had my vehicle in 4wd high. As I was going down hill I let off the gas and started braking. When all of a sudden my 4wd drive switched into neutral. I am wondering what could cause this to happen and whether it's an issue or not? It is snowing which was my purpose for being in 4wd.

I have recently bought a new truck this month and everything was nice and dandy till i noticed an annoying jerking at 45-50 mph. The check engine light didn't come on till recently when it got really bad and would barely start. I hooked a code reader up to it and it said cylinder 6&8 misfire. So I had the coils replaced on those two cylinders and it seemed to start and idle better.
So I took it on the interstate to see if the jerking was gone as well. and it still jerks at 45-50 just like before. I was going to take it to the dealership to have them figure out what the issue is but that's 100 bones just to figure out what the problem is. My mechanic doesn't want to mess with the spark plugs because he knows they always break.

I have an 05 f150 5.4 and when it shifts into overdrive the whole truck starts jerking, if I turn overdrive off it shifts and runs smooth through all other gears. When it does start jerking if i give it gas and speed up it stops and runs smooth?

I have an 04 f150 with the 5.4 and recently, within the past few months, I've noticed some "jerking" especially when accelerating. At first, I thought it was the transmission, but the jerking does not coincide with the shift patterns. It jerks and stutters around 45-50 mph and 1500 rpms especially under light acceleration. Not sure if one is connected to the other, but also have no real power, I'm barely moving under heavy acceleration. ...What could I be looking at? I am thinking it has several options, I just need to know which one to explore first...cheap, meaning fuel pump/filter?? MAF?? Or Engine Coils?

I have an 06 F150 4x4 crew cab w/ 108k miles and the 5.4 flex fuel v8. I'm getting a pretty bad jerk while using the cruise control and going down hill, seems almost like it is turning the cruise on and off rapidly while it is rolling. And if so, were you able to fix it and what was the fix? It works perfectly on level road or going uphill, just does this going downhill, very consistently. No lights on the dash, and no other issues.

I'll try to explain what the truck is doing best I can. I'm not sure if it's the engine or tranny. When you lug the truck on a hill or put a load behind it and lug it the truck jerks like the engine is cutting out or the tranny is jerking, I can't tell which. You can drive it all day long on a flat road or small hills and you can't make it do it. It does it worse going up a hill with a load behind it. You can lug the truck on a steep hill let off the accelerator and mash it back down and it will do it almost every time. I've tried overriding the overdrive and it still does it. If you keep the rpms above 2000 up a hill it won't do it. I've had it checked by a transmission shop and they couldn't make the truck do it. Also it doesn't throw any codes or put the check engine light on when this happens. 2007 F150 supercrew 5.4 auto, with 88,000 miles.

i have an 07 ford f 150 5,4 liter. at speeds between 45 and 55 it has like a sputtering and jerking loss of power. I had a computer hooked up to it and it said fuel pump replaced it but it is still doing it, what this might be.

I have a 92 (3.3L) New Yorker 5th Avenue that has makes the car jerk badly going uphill and occasionally makes a backfire / misfire noise. It is a general jerking, not localized (right / left front) by feel. It starts ok and runs smoothly at idle but once you put it in drive and start acceleration, it begins to jerk. It has over 200k mi. I have had the fuel filter replaced, new plugs and plug wires put on. Mechanics have ran codes on the engine and transmission and tell me that no bad codes show up.

I just purchased my Elantra MD for just 2 years. Yesterday I went uphill (not steep) then decide to change from auto to manual, then I move the stick, it shows I am currently in gear 5 so i downshift to 4. After a few second the was a 'jerking' with 'thump' sound from the bay. My rpm came down slowly, i pushed the pedal but the rpm wont go up. it just glide. Shut down and up the engine changed nothing. When i try put reverse gear, it reversed fast as if i pushed the pedal, but i am not.

i own a 2005 f150 supercrew fx4. Today as I was attempting to go out of town I was accelerating up hill and heard a noise, sounded like air coming through a window seal or scratching, which is not the problem. The noise only came on when i increased the acceleration, there is no power loss, the truck still accelerated properly and had good power, just that the noise came on. so i returned home only to hear the problem on flat land also, when pressing the gas to accelerate. The truck seems to idle fine and have no problem with low acceleration.

I have a 07 with the 5.4 engine and it has started to jerk or miss sometimes when I'm pulling my trailer. I'm thinking about changing the plugs, but the dealership is telling me they will break off in the head.

friend with their Mountaineer issues and i have no clue where to go or what to do now. Shes had it for approx 2 months and didn't have any issues till this one. It died on her while driving and would rarely start back. She had it towed to a crappy garage and the lazy mechanic stood beside it and "listened" for the fuel pump. He said he didn't hear it, gave her a quote and walked away. She then had it towed home and i was contacted. If i get under the truck while she turns they key on, i can hear/feel the fuel pump. It's quiet, but there.
But now, you can turn it over for about 10 seconds and it will start the almost immediately die. During one of the times before she had it towed, she took it to auto zone and had the codes pulled. I have a scan of all the detailed info i can post if needed, but it pulled: P2104 P2106 P2111 and P2135. Each of those mean something along the lines of a sensor but the only two sensors mentioned in more that one code is the throttle position sensor (TPS) and the Electronic throttle control (ETC). I've been trying to research what i can on it, and from what I've read is when these codes are pulled, those two sensors are rarely the problem.
