Ford Super Duty (1999-2016) :: 2008 F250 - Vibration When Accelerating From A Stop And Under Load


Jan 19, 2009

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?

Ford Super Duty (1999-2016) :: 2000 F250 - Vibration When Accelerate Pretty Much Any Load Above 1200 RPMs

I have a 2000 f250 crew cab short bed 7.3 on a 6inch bds lift and 37 inch tires. When I accelerate pretty much any load above 1200 rpms I can feel a vibration, kinda feels like it may be coming from the front left but I'm not sure. I have heard that a wheel bearing going out can cause this, would this maybe be what's causing it?

I thought wheel bearing because it kind of sounds like there's a howl when decelerating, probably when accelerating as well but the trucks too loud and I can't hear it. or also have heard motor mount gone bad, I've also heard ujoints but the ujoints were done this summer. the front ujoint is bad but the front driveshaft shouldn't be turning when out of 4x4 and hubs unlocked.

Ford Super Duty (1999-2016) :: 2007 F250 - Shimmy When Accelerating From A Stop / Turning Right Or Left

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..

Ford Super Duty (1999-2016) :: 2008 F250 - H&S Tranny Rev Up While Accelerating - Slipping?

I have a older minimax with the latest updates and have noticed that under full acceleration the tranny seems to rev up faster than the truck is accelerating. This occurs i think in 3rd gear like accelerating onto a on ramp etc. Kinda like its slipping if you know what I mean. I'm running the mild tunes in tow mode. Everything else seems ok.

Ford Super Duty (1999-2016) :: 2008 F250 - Wipers Came On With Switch In Off Position And Won't Stop

I have a 2008 f250 with 6.4. Was sitting my truck with key on and motor off listening to radio on lunch and my wipers came on by themselves. Switch was in off position and we're in slow speed. If I turn switch they wouldn't change speed til high position. Turned key off and back on and they came on still. Pulled 30 amp fuse in battery junction box to shut them off.

Ford Super Duty (1999-2016) :: 2008 F250 - Truck Will Not Stop Shaking When Driving

I have a 2008 F250 crew cab lariat 4x4 with 20 inch factory wheels that the steering wheel shakes during normal driving left to right. I bought this truck with 1500 miles on it. This shaking started at 50k miles and I was thinking it was a balance issue so I got new tires a month later since mine were about worn out anyways. They were factory replacement nitto terragrapplers. Shake was still there, swapped out for another set of nittos and shake still there, swapped to BFG AT KO's and shake better, but still there. I have gone through 10 or so balances, 5 roadforce balances, 2 alignments at 4 different shops including the ford dealer through the 3 sets. My wheels are scratched to hell and back from the careless people at the tire stores from so many balances.

My truck sat at the Ford dealer for a week just the other day and they changed the steering stabilizer. I thought it was gone, but a a few days later shaking started again. It almost feels as if every little bump, rut, crack in the road the steering wheel feels and shimmies (doesn't matter the speed, gets worse and more noticeable at higher speeds). The Ford Dealer says can't duplicate, but then when I go down there and test drive with them it's "oh yeah I see that, it shouldn't be doing that". The Ford Dealer says they can't find anything loose in the front end when I tell them to check tie rods, bearings, etc.

My truck has 62k miles on it now and it's driving me to the point of thinking about trading it on a Chevy. I love my truck, but it kills me everytime I make a payment and it rides like crap. I am still under extended warranty so I need to get this fixed before it goes out. I've also noticed that if I turn my steering wheel back and forth real quick while driving like warming up for a Nascar race I can feel a bumble in the steering wheel. This is NOT the death wobble as I use to get that around the 20k mile range and it disappeared and has never been back.

Ford Super Duty (1999-2016) :: Vibration When Starting Out In First Gear Under Load?

I have begun to notice a vibration when I am in first gear starting out with a bit of a load. The vibration goes away as I gain speed and the load reduces. None at any of the higher gears. If I take off real easy and allow the truck to gain speed without pushing it, the vibration does not exist. The truck is the one outlined in my signature. It is equipped with a 3 speed auto with overdrive. I am thinking this could be a U-Joint that might be starting to go out.

Ford Super Duty (1999-2016) :: 2008 F250 - Permanently Stop TPMS Light From Coming Up On Dash?

Am I the only one who thinks the tire pressure monitoring system is a silly feature? Is there any way to delete this and stop the light from coming up on the dash? I want to do new wheels and tires on my 2008 f250 and I don't want to deal with the tpms. Can it be tuned out from the computer?

Ford Super Duty (1999-2016) :: Vibration Mostly Noticeable While Under A Load Like Climbing A Hill

My current 08 duty was bought with what I believe to be a procomp 6" lift modified to an 8" lift. The 100 mile drive home after buying the truck showed a tiny "hop" in the rear. I ditched the 37s for some new 35s. Still a tiny hop, mostly noticeable while under a load like climbing a hill. I pulled the rear driveshaft and had it fully rebuilt with a new carrier bearing as well. Still gots the hop? The truck has a carrier bearing drop bracket but I think it may be insufficient for the lift.

The rear driveshaft still has a slight bend in the middle of where the two driveshaft pieces connect. Are the 2 piece driveshafts on your 8" lifted trucks sitting straight with each other or do they have this bend as well?? I am thinking if I get a bigger drop bracket it may cure this slight hop I have? Lots of lifted trucks where I live but they are dam near all shortbox with 1 piece rear shafts so I haven't been able to find one to compare. By the way, my truck also has pro comp rear traction bars..

Ford Super Duty (1999-2016) :: 2015 F350 - Takeoff Vibration Or Shudder Under Load

My 2015 F-350 Super Duty has a noticeable vibration between 5 and 15 mph when accelerating with my 5th wheel. The 5th wheel is heavy--around 14000 pounds. The pin weight is heavy--around 3000 pounds. The Owner's Manual says on page 191 "When driving with a trailer or payload, a slight vibration or shudder may be present due to the increased payload weight..." (This was brought to my attention by my dealer.)

Seeing the thousands of F-250 and F-350 Fords pulling 5th wheels out there on the road, I wonder how many have this "slight vibration or shudder" and what they have done about it.

Ford Super Duty (1999-2016) :: F250 - Skipping / Surging Under Load

I have a 99 f250 that seems like it has a bad coil, under a load it starts surging or bumping ( like it has in the past and I found a bad coil), I went through and unplugged each coil one by one while idling, couldn't find a bad one, so I bought a new coil and went through and rotated the coils, nothing worked, no check engine lights on.

Ford Super Duty (1999-2016) :: Vibration While Accelerating?

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.

Ford Super Duty (1999-2016) :: 2003 F250 5.4 - Starts Cutting Out When Under Load

About 20 miles into it, and it starts cutting out on me under load, over about 1/4 throttle. I baby it a ways further, and park at a wal-mart. Idles fine, but once again, after 1/4 runs like crap, acts like it's back firing through the intake spit and sputtering. Have the wife come pick me up since I was heading to work. Decided to shut it off, and restart, and it acts like its never had a problem.

Was messing with it today, and let it warm up in the driveway. Once it got hot, same story good 1/4 throttle, past that, not so much. Shut it off, started it back up and drove it to see if there's any codes at vatozone. Drove good (laying into the throttle) for about 2-3 minutes, back to same behavior. Hooked up code reader, no current codes, and no historic codes. Although I did notice (actually since I bought the truck) that the check engine light never comes on, even at initial start up. Looking at my spare cluster, it's an l.e.d. So no bulb out I guess unless the led is bad. Truck has around 130,000 miles on it. Everything is stock.

I'm leaning toward a fuel pump, a clogged cat, or a fuel pump relay or cutoff switch problem.. It doesn't have any other issues than that, and has been a good truck for the 10k miles I've owned it... 2003 F250 5.4...

Ford Super Duty (1999-2016) :: 2001 F250 - Slight Bucking Under Load

I have a 2001 Ford F-250 5.4L V8. 117,000 miles. The problem I have been relentlessly trying to diagnose is a slight bucking that occurs under load when the truck is in overdrive. When the truck bumps up to higher RPM's it is fine but when it is around 1500-1700 RPMs on the highway it does a small buck like I'm hitting a bump in the road. I know there are many threads on this but none of them have gotten me any closer to a resolution. It also seems to have a bit of power loss when accelerating. Things I have done so far.

-Spark plugs and COP replaced about 1000 miles ago
-New fuel filter
-Cleaned MAF sensor
-Cleaned throttle body
-New PCV
-Seafoam treatment in gas and through brake booster.

Ford Super Duty (1999-2016) :: Soft / Low And Short Grumble From Rear End When Leaving A Stop With Load

1999 F350 7.3TD auto 4x4 crew 8'. I've noticed that I get a soft, low, short grumble from the rear end when leaving a stop with a load.

My son just used the truck and says he thinks the rear is binding while in reverse while backing into a parking space, wheels turned.

What are the potential problems here? I've heard a fluid change with "anti-slip additive" could be the answer. Which anti slip additive should I use?

Ford Super Duty (1999-2016) :: 2008 - Overheating Under Load

I have a 2008 powerstroke. Dpf and egr have been fully deleted. SCT tuner seems great and have had no issues since installed 6 months ago. I recently hooked up to my camper and headed up a mountain pass. As soon as I started uphill the engine overheated. I allowed it to cool and tried again with the same result. Eventually had to unhook and have another 6.4 (this one being a 2010) pull the trailer the rest of the way. Haven't had any heating issues since unhooking.

Ford Super Duty (1999-2016) :: 2002 F250 V10 Rough Idle / Misfire Under Load

I have a 2002 F250 CCSB Lariat 4x4 with the Triton V10, I'm up to 232,000 miles so far and fairly happy with the old girl. Just this weekend, I noticed some hesitation when at idle and even more rough running when under slight load. The misfire/hesitation is worst when going up a slight hill, when the truck is accelerating at low RPMs.

I am getting zero trouble codes or freeze frame conditions on my scanner. What should be my order of diagnosis? Vacuum test at line from PCV to TB, COP test? EGR inspection? Plug inspection? Also, how do you test a coil if resistance is not a reliable method?

Ford 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?

Ford Super Duty (1999-2016) :: 2006 F250 - Misfire / Stutter On Hard Acceleration Under Load

06 250 5.4 40k on it, usually when cold and accelerating engine will misfire and stutter and then continue accelerating. The wrench light will flash sometimes but it wont store a code. This used to be vague in occurrence but has now started to be more a common occurrence even when up to normal operating temps.It seems only to misfire /stutter on hard acceleration or towing/hauling heavy loads. The only answer I got from a mech would be to do a computer reflash, not sure why /how this would fix whats going on.

Ford Super Duty (1999-2016) :: 2002 F250 - Misfiring Under Heavy Load Or High RPMs

So basically I thought it would be a great idea to degrease my motor from the top down.... After washing I start it up and drive down the road to head abunch of misfiring under heavy load or high rpm's.

My problem is that the misfiring won't throw a code. I then proceeded to buy a new ignition coil (thinking this was the problem) but with no code to go off which cylinder was bad I just switched the good ignition coil into each cylinder and starting it.

Up each time. None of them seemed to make it better. Also the injectors all seemed to be good. So what to do ?
