Ford Super Duty (1999-2016) :: 2002 F250 - Vibration When Letting Off Accelerator
Feb 1, 2014
So, I'm slowly but surely eliminating a terribly shaky front end on my 2002 F-250 7.3L 4x4. First was a new carrier joint on the front drive shaft. Didn't work much, but the shop said the darn thing was falling apart. Next thing I did was new wheel bearings and manual hubs. Less vibration for sure. But the last remaining issue, in terms of vibration, is that when I let go of the Accelerator going at any speed above 60 MPH, it makes a horrible horrible noise, and I could feel a vibration. It shakes the whole truck, but I can very noticeably feel it directly in the gas pedal. It's really only an issue during deceleration. What could it be??? Drive shaft U-joints? Torque Converter? Something else in the Front End? Something in the engine even?? I don't exactly have the funds to tackle every possible solution.

My '11 F250 stock w/airbags has a mild shudder when I let off the gas approaching a stop light. If I air the bags up to about 20 lbs it appears to go away, or at least is undetectable. I don't notice this if travelling at a higher rate of speed on a highway but only when slowing down from a lower speed (<40 mph). What this could be?

I have a 02' 250 4x4 with 250000 miles on it. While driving between 55 to 65 mph there is a roar and vibration that seems to be coming from the rear. I have about 35% tire tread left and have had the rear tires balanced and it still does it. Having issues with drive shafts unbalanced or rear ends?? I am not sure where to start....

2002 Ford F250 4x4 Superduty Lariat (4 door). Just changed the locking hubs to a new set of Warn manuals. I began to periodically hear what sounds like a rumbling/bearingish/howling kinda sound. Happens when you hit a bump at any speed...then howls till you hit another bump..goes away..then process repeats. Come to a complete stop, and the sound usually goes away till you hit another bump. The hubs are "free" at this time.
Heres the weird thing...when the noise starts...I switch it into 4 wheel drive on the dash...the sound instantly goes away. Click it back outta 4 wheel drive (hubs are still unlocked this whole time) and the sound is gone. drive some more down the road, maybe hit a slight bump, and the sound returns. Switch it back into 4x4...sound instantly goes away. Its not really in 4 wheel drive, cause the hubs aren't locked in...but that cures it till I take it back out. What could be causing this howling ? Its getting worse, and you can feel a slight vibration in the floor now when its doing it.

I have a 99 F250 7.3PSD; I upgraded the tranny cooler after an episode of overheating while backing up a hill.
The truck has done well, hauled a few tractors with it, but recently I have noticed something that seems scary. When going downhill, I often relax on the accelerator. Usually there is some passive engine braking as happens with any auto tranny. Recently, the truck just coasts - it is as if you feel the tranny shift into neutral and you just coast, except I didn't shift. While this is happening, the accelerator pedal will not rev the engine. You can put the pedal all the way down -> rpms at about 6-800. No response.
At the bottom of the hill (so far) the engine gets louder. the rpms drop, and the accelerator works again. Every time, so far. But, if IO am going down hill, and want to accelerate to execute a laneg change or something - I can't. AFAIK, everything A-OK after the new tranny cooler. levels, etc.

On a cold crank the engine idles rough until it warms or the accelerator is pressed down. Also runs rough going up hills or towing. Check engine light is on and is throwing the code for bank 1 to lean and cat performance below threshold. Cats have been tested, good. Fuel trim tested, good. One mechanic said noth8ng is wrong with it well, there is. 2011 f250 6.2 gas...

I have a 2011 f250 6.7 and I have a very bad vibration between 40-50 that seems to peak around 45-47. It also starts again at 80+ . the dealer told me they could not find a problem. Then another told me its normal. The tire shop around here told me the tires were shot so I bought new tires. No luck. It does not affect it if I change gears.

I have an '03 F250 Super Cab, 7.3L PSD, 4WD. I've started getting a large vibration between 40 and 60 mph. Started after driving on the PA highways towing a trailer with a car and hitting several deep pot holes.
I have had the wheels balanced, rotated, balanced a second time by a different shop and had them perform an alignment - Still No change.
The garage I took it to said the hubs were shot so I had them replaced - supposedly with Moog, lifetime warranty hubs. Still - No Change.
The tie rods and steering linkages are a year old, so unless something was damaged (visually, they look good, and feel tight) it probably isn't them.
I replaced the ball joints around 80,000 miles and now the truck has 155,000 miles. They appear to be ok, with maybe just a little movement in the Passenger side upper.
If there is any movement at all in the ball joint, will it cause a vibration?
I plan to rotate my full size spare through all 4 corners this weekend to eliminate the possibility of a bent rim.
I have another set of ball joints and seals on order which should arrive next week. Probably next weekend's project.

I have a vibration in my 2001 f250. At about 45 to 55 it vibrates. I have changed u joints in the rear drive shaft. Pulled it again tonight. U joints look good, no play. I am going to pull the front shaft and see if it makes a difference. I did notice some play on the rear shaft where it slides. Could this be causing the problem?

I have a 1999 F250 super duty with a mean vibration at 70+ mph. It is a 5.4L manual trans manual 4x4 extended cab short box with around 250k miles on the body and 50k on the motor. It is a one piece drive shaft with the double knuckle at the t- case. it has had a vibration in the drive line since i bought i about a year ago. there is almost zero vibration at 60 mph but at around 70 the vibration starts to get really bad. The vibration is speed related because when i push in the clutch or pull it out of gear the vibration is still there. i seems to vibrate more when winding out in 3rd and 4th gear but that may just be because off the exhaust resonating or something. I have already done u-joints, balanced the drive shaft, put brand new tires on mounted and balanced, replace transfer case output bearing and both front hub assemblies. the vibration feels like it is coming from the trans or transfer case. every thing i tried made very little impact on the vibration. I'm a loss and i don't know what else to try. i know the throw out bearing an pilot bushing are bad and the clutch is well worn so ill be replacing that soon but i don't believe that is causing the vibration.

I am new to the Superduty and the Diesel world. I just purchased a used 2006 F250 SD XLT with 79K miles on it. This truck has a brand new 6 inch rancho lift. I just bought brand new 35x12.50x18 toyo open country AT tires and new 18 inch rims. I have the steering box replaced, new brakes all the way around, front end alignment and the Turbo pedestal secured.
However, I am still getting a vibration in the floor going down the highway when i hit 70MPH under acceleration? Once I let off the gas the noise goes away.

I have a 15 F250 CC SB 6.2 4x4 that is suffering from a driveline vibration. Had the shaft checked for balance and it was off. It's a little better now but still there. Checked all the angles and they're correct. Also came up with a curious observation that all CC SB 4x4's have a slip yoke driveshaft at the transfer case while all the other trucks have the fixed yoke. This appears to be my source of the vibration.

I have a 1999 f250 SuperDuty with a nasty vibration That begins at about 70mph. The truck is an extended cab 5.4l Manual trans 4X4 with a one piece driveshaft (No mid bearing). The Vibration appears to me to be a driveline vibration that is speed dependent. It is the same in gear, out of gear clutch in or out. I have replaced the wheel bearings/hub assemblies on all four corners, completely rebuilt and balanced the driveshaft the driveshaft, removed the front driveshaft, put brand new tires mounted and balanced on all four corners, new clutch, had the flywheel turned and balanced, and replaced the transfer case output bearings. Pinion bearing feels tight and does not leak.
Also the Input in the trans felt tight when i had the trans out. The truck had the vibration when i bought the truck and still vibrates after i have done all of this work. i did not change the motor mounts because they looked fine. when i bought the truck the tabs on the extension housing holding the trans-mount to the trans were broken so i make a huge "exhaust clamp" to straddle the trans and bolt to the trans mount.
After driving the truck up north last weekend the truck seems to shake going taking of at lower rpm as if the motor mounts and trans mounts are bad. I guess my questions is can a bad trans mount, motor mounts cause this Vibration at highway speed. if so is there a way to fasten the trans-mount to the extension housing without replacing the extension housing. If not what else can cause this issue?

My 2003 Ford F250 V10 seems to have a vibration, sometimes at all speeds and sometimes at freeway speeds. I replaced front hub assemblies and ball joints and rear calipers last year. When braking i have a vibration in rear as well, which I think is from uneven rotor but can it be causing my vibration? Also sometimes I can smell hot brakes from the rear.

Now that I use my truck as a daily driver I am noticing a vibration under acceleration at 30-35 and constant vibration at 45-50 accelerating or maintaining speed. I have replaced all three u-joints as well as new ribbed highway tires all around and still have the vibration. It seems worse in OD. I have done a little research and am either going to shim center support/machine a new one or have a one piece shaft made and need info on how to successfully gotten rid of this vibe on their truck mainly the amount of shimming required and the final driveline angle. It seems that most posts regarding this issue lean towards the fact that the 45-50mph vibe is normal for my year super duty and that's probably right but I want to remedy problem not "live with it!" (10 mile 45mph stretch to work @ 4AM, vibe bugs the heck out of me!)
Truck is 2000 f250 SC 2wd 4r100 3.73 gear currently 51000 miles.

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?

2003 f250 crewcab 6.0 auto 4x4. I all of a sudden started feeling a vibration under the truck near the back when I accelerate and when I let off the gas no other time. No noises or clanking just vibration. I can wiggle the driveshaft inside the carrier bearing do you think that could be it or is it the rear end.

02 CCSB, and I have a vibration in my driveline that's starting to drive me nuts on my commute every day. I can feel it faintly starting at about 45 mph, whether the torque converter is locked or unlocked. The vibration peaks at about 60 mph and goes away at about 65+. My u-joints are all moog and grease them every oil change (about 120k on them now). At this point I suspect the carrier bearing, yokes, or even u joints but there's not much play. However the rubber around the carrier bearing is in rough shape and dry rotting. I'm curious if there's a test I can do to find the culprit.
