Ford Super Duty (1999-2016) :: 2014 F450 - High Speed Vibration
Aug 11, 2017
My truck has had a bad vibration for some time know, it started around 41,000 miles and took it to my local Ford dealer... the told me I needed tires and that my airdam/bumper extinction was loose and causing it to vibrate . I put front tires on I fixed the plastic on the bumper and replaced steering stabilizer . Vibration continued to come and go after all of that so I replace the steering stabilizer with a different steering stabilizer .
I noticed that the front seals for my four-wheel-drive allowed the shaft to move up and down by more than a half an inch of play.so I had Ford replace the front hubs and seals . Vibration is now worse and more often. It happens every time I am between 50-54mph. I am going to put 6 new Michelin defender Tires on it and new shocks and a Monroe steering stabilizer.

Purchased new 2016 450 platinum. Has less than 800 miles on it and has a terrible vibration between 70-80 mph... Already have taken to dealer who stated there was a wheel out of balance and that they fixed the issue. But still present.

I have a 2014 F 450 and today one of my trailers will not engaged the brakes and it is saying on the display that there is no trailer connected. I cannot engage the brakes manually with switch.
I have running lights, I have brake lights I have hazards lights and turn signals. The brakeaway switch is not engaging the brakes when removed, I hooked up to another trailer of mine and it recognized and acknowledged being hooked to a trailer.
So... I know it is something with the trailer but what wire I should be looking at on the trailer?

2014 F450. Front end and steering wheel shake violently when braking while towing a 20,000 pound trailer down a long and steep highway grade. It does not happen when towing my 12,000 pound trailer down the same highway. Could I be setting off the ABS braking system?

I am having overheating problems at high speed/high rpm/under load. The only codes ive gotten are EGR dpfe (0401). Truck is 99 f250 with the 6.8 new egr valve, dpfe, new coolant, new thermo, new sensor under manifold. I blew 90 lbs air pressure thru the egr lines, big and small, they were clear.
So whats left? I never hear my fan clutch......should I? I've had other trucks and the fan roared when first started for a few seconds, and then again when you were hot...they really roared.
Is it possible for the egr port where it goes into the throttle body to be plugged? guess I should've checked that when I had the egr off. Would an aux. fan be a waste of time?
This is pulling a 3500 lb camper trailer up moderate hills.

I just put a dual exhaust kit on my truck (cherry bomb extreme, single in dual out), and I've started to notice that around 2100-2200 RPMs, there's a high pitched vibration in what seems like the tight hand corner of my regular cab. It almost sounds like the glass in the window is vibrating, or a loose bolt, or something like that. Very high pitched, very noticeable.

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 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?

2004 F350 single rear wheel with 8" suspension (springs) lift and 37" tires all put on in 2005. Having low speed vibration 15-20 mph on accel and decel. Recently put on thick aluminum rear dif cover and vibration seems to have come since that install. Used Mobile synthetic fluid and 4 oz of Motorcraft antifriction additive and 4 oz of off brand. The Mobile fluid and antifriction have been in my barn for over 5 years in the winter and summer. I just changed the carrier bearing and all U-joints look good. Any chance the fluid and antifriction additive could be causing this? Truck has 66k miles.

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.

We've gone through pretty much every other option as to the vibration on take off and other high torque situations and have pretty much settled on the the driveshaft as the issue. I added traction bars recently thinking that the old leaf springs just aren't up to the job anymore. That seems to have worked some but it's still there. We've gone through the rear diff also and that's good. I'm looking at options for replacement of the shaft. What are the current thoughts on one piece shafts? Is aluminum the better option?

I have a 1999 F450 that was bought new as a cab and chassis. The truck belonged to my dad who passed away two years ago and now I have it. I am wondering if it has 4.30 or 4.88 gears. The rear end is huge! It has an aluminum cover with cooling fins on it, not sure if they both had that or not. I looked online and I think it said all cab and chassis had 4.88?

My 99 f450 7.3 runs bad on first start of day. I checked the codes 3 codes p0475, p0470 and p1247. Now here is what I tried I plugged it in over night and it will start and run as should the next morning with out side temp 47. Drove the truck late yesterday evening didn't plug up tried it this morning with a outside temp of 47 truck starts but missing and like of power. My problem seems to be temp related. Will low boost pressure cause this problem what do I need to do?

I have a 99 F450. I have an ABS light on. No codes (at least not that my code reader can pickup), but I am also not having any issues. Brakes work fine. What to swap out or where to look?

Can an f-450 with a blown 6.4 diesel received an transplant from an f-350 V-10.
How much would need to go over from the f-350 to f-450?

I have an 02 F450 with a dump bed an just under 45,000 miles (was barley used by the first owner). This maybe unrelated to my problem but is worth mentioning. This past week I noticed a small puddle where I had previously parked at a customers house so I checked the oil. I was about 2 quarts low. I followed the oil trail up and found a pool in the valley. One of the high pressure lines were loose and the seal was chewed up so I replaced it and tightened it. No more oil leak.
Now my new problem. Two days later, after about 45 minutes on the interstate driving about 75 mph the truck started to rapidly lose power as if it was running out of fuel. I heard a loud ticking sound coming from the engine and the more I tried to accelerate the worse it got. I pulled over and the truck stalled. I thought that maybe my fuel gauge had crapped the bed on me because it still read a little over 1/4 tank. I called a buddy and got more deisal in it and it started right up. We'll after about 5 minutes of 60 mph it started to happen again. So to fast forward... I opened up the tank and found the the strainer had crumbled in the bottom of the tank.
So I cleaned out the screens in the sending unit and replaced the strainer, replaced the fuel filter, and reverse blew out the lines. I read about checking the hpop reservoir for oil and it is present. So to sum up, as long as I stay under 60mph or so I can get about 5 minutes of run time before the truck starts to stutter and stumble. If I shut it off for about 5minutes I can go back up to 60 again but it the cycle continues. 5 on and 5 off. If I start the truck after say 30 seconds after shutting it off it sounds like it's going to die and has no power at all. I have worked on a lot of vehicles but none with anything like this and this is my first deisal. What do I do to get this beast back to normal?

I have a 1999 F450 Diesel dump truck. Automatic. The problem that I have is that the truck will drive VERY SLOWLY while the rps go up.
You can hear the engine revving up, and a strong air sound when doing so (do not know if intake or exhaust, but its like a strong wind sound. And not like a hiss, so I do not think its a vacuum leak).
The transmission goes through gears fine, but it does the rev up thing through every gear. So I am wondering if something like the torque converter might be broken or slipping.
For example, if you go with the loaded truck up a hill, you have to really push it to keep any type of speed. Or when you get off a red light.
When I bought it used, I thought that it might have a really short final gear. But that would not explain the high RPM and no push.....
No codes at all.

It's a 2004 F450 super duty, no power steering. The pump seems to function, no pump whine. I was told that it may be the steering gear box it's self.

I've got a 2004 f450 6.0 diesel. This thing will start and run great when it's cold. Then when it gets to operating temp, around 190, it will shut down. This is getting worse and worse.
A little history, it was doing this for awhile and a had a few other issues before this. Puking antifreeze, stiction issues, and bad exhaust manifold. Since it wasn't running great I figured why not pull that cab and take care of these issues.
As of last week she got new head gaskets, new exhaust manifold, new injectors, updated standpipes, updated dummy plugs, new o rings on hpop (yellow on the bottom), and a new pipe to the oil pump. I have the old style it's not the stc fitting.
All that work, it still stalls when warm. I monitor with a scan gauge 2. ( Big diesel tech Ron's fan) ...
First thing, give here two second crank start right up, runs better then ever. Gets to operating temp, rev it up, then stalls. Ipc is at 85% ipr gets up to 180 psi.
Unplug ipc, shows 765 psi on the ipr still no start. Put shop air to her and I can't hear any leaks ( probably 15 mins or so).

I have a F450 that I bought a few months ago and have been having trouble with Fuse location 35 blowing. When I purchased the truck the 4x4, tow/haul, and reverse sensing system worked because I had to use it loading and unloading my boat this fall. Since then the snow fell and when I tried to put it into 4x4 I noticed it would not. I checked the passenger compartment fuse (loc. 35) and it was blown.
So I figured it was an easy fix, changed fuse, and it immediately blew again, and again. So then I started checking components related to fuse 35. First i checked the tow/haul switch in the shift lever and thought it was that, so I replaced it, and it still blew fuses. Next, I unplugged the reverse sensing systems and still blew the fuse. Next, I turned my attention to the transfer case shift motor. I replaced it and still blew fuse. So at this point I am stumped.
It is probably worth mentioning that when I replace the fuse initially and turn the key over, all systems work. I can switch the dash switch to 4x4 and it will shift, also the illumination light on the dash comes on. I can also toggle the tow/haul switch and the illumination light on the dash comes on as well. The reverse sensing system also works as well and the light in the switch works as well.
Now and important thing to note is that it seems to hold the fuse for a minute or more with the engine off/ key on, when I start the engine, it works briefly but then the fuse blows. I am not a service tech. by any means but am very comfortable under the hood and have a fairly good understanding of electrical components and their operation. It seems to me that somewhere in the circuit that there is a short to ground or a faulty component(module) or something completely different.
The fact that it takes a minute or so to blow the fuse as compared to an immediate blow when the key is cycled to power on. I would like to fix this myself as with anything I do, I like to educate myself through diagnosis/repair. The last piece of information with mentioning is that before I purchased the truck(30,000 miles ago) it had a factory reman engine installed at a ford dealer. If worse comes to worse I will have to take it to a Ford dealership for service but would like to keep it in house if I could!
