Ford Super Duty (1999-2016) :: 2006 - Vibration / Jumps Up And Down At Certain Speeds
Jan 25, 2008
I am yet another sufferer of the 40mph vibration syndrome I commonly read about on this site. I have had my 2006 f350 club cab sd to the dealership about 7 times for this, and now am being told it is a normal characteristic of this truck. They have replaced wheels, tires, vibration machine analyzed, put on a vibration damper, etc., but nothing fixes the problem. It has done it since the day I drove it home.
How many of you out there are upset about their super duty that jumps up and down at certain speeds? Lately, my dealership has had my truck more than me. From the amount of posts I see about this problem, I am certainly not alone. Ford is now trying to brush me under the carpet, yet I have a truck with a built in gyrator that is totally unacceptable. The truck now has about 20,000 miles of bouncy misery on it, and it isn't getting better.

New, 2 month old 2015 CC, gas 4x4 with standard bed. At 50-55 I have a rolling vibration, or it can even be explained as a slight growl. Seems worse since I upgraded to 285/75/18 Toyo AT's and new wheels. If i speed up to about 60, goes away. If I pop it down to 5th gear, it seems to go away, however, I need to try this a few more times to make certain.

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.

The other day I pulled a fella out of a ditch. It was a dulley 350 with a lowboy trailer and a small dozer on it.
Well, after finishing and driving away. I inadvertently left the truck in 4x4 while driving on wet pavement at speeds ~30 mph. What I noticed was: when I let off the accelerator there was a low growl/vibration noise coming from the front/under the floorboards while the truck coasted to slower speeds.
I have never had my truck A) in 4x4 on clear roads or B) at speeds above 10mph in 4x4. Maybe they all make noise at low speeds in a quite cab in 4x4. I wouldn't know, I've never driven it under these conditions.
So, can you hear your truck in 4x4 when not giving it gas and coasting on the road?
I did not think I put the truck through too much while pulling that fella out, but now I'm wondering....oh, and I at one point I coasted forward and ran over the towing strap that was attached to my front pull hook and it made a HECK of a noise...could that have done something bad?
4x4 still works, and everything seems/sounds fine otherwise. I might just be hearing the front end putting friction on the transfer case and I can hear it in the tranny as she coasts to a stop (it goes away as soon as I press the accelerator at any speed) but like I said, I've never noticed this before.

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.

2001 F250 SD, V10, Auto, 155K miles
While driving home from work I noticed the needle jump from around 55 to 70 on the display, then settle back in at 55 ish. First I just caught it out of the corner of my eye, but watched more closely, and it did it again as I drove. The tow/haul override button on the shifter was blinking also, (as if it was "Mad" about something)..
Then I noticed that the jump of the Speedometer needle was linked to when I changed from High to Low on the headlights, and vise-versaI was NOT in cruise mode The voltmeter did not EVER waver. (I thought that the increased current might be causing a temporary problem of sorts). Where to start looking?

The tach in my 01 F250 PSD has become intermittent. It works properly some of the time, not at all some of the time, and jumps up and down some of the time.
Does it get it's signal from the CPS? It has a blue CPS that's about a year old and the truck runs fine?

My 2003 F250 6.0 It started about a month ago and got worse. Let truck idle for 4-5minutes and idle will jump a few hundred rpms. Got worse as it idles and cant figure it out. It eventually died and died once while driving but starred right back up.

Ive read here that our trucks can lose all of their AC fan speeds except High - mine has done that as well. However, even High on my truck doesn't blow much air. I looked behind the glove box for an interior air filter, thinking it might be clogged but couldn't find one. What could be stopping my blower from putting out?

I have a 1999 f350 v10 stock truck. It has plenty of power when it's cold out or raining or I'm on backrooms or highways but if I drive through town on a hot day the transmission kicks bad I have changed the fluid and filter, it also seems to shift at a high rpm from 2nd to 3rd. Unless I you let off quick and go back on kinda like engaging a 2 speed rear end. Does it need a bigger trans cooler or is the trans shot

The other day I pulled into the parking lot put it in park and let it idle for a couple minutes, it stumbled and when I started driving off it was missing. I pulled the valve covers off and check the connection.. I drove it home and it had a bad misfire at 1500 RPMs. The truck shook violently at that RPM but when I got it up over 2000 smooths out..

Only 2 speeds of the 4 speeds are working on my blower. I was thinking it may be the switch, but someone at the shop told me to replace the blower resistor first. I did that and still only have 2 speeds. Im guessing I need to replace the switch now?
Also, I am having problems with my heat adjustment. I have it set to warm (half way between cold and hot) and out of the blue it will start blowing hot. I turn it down all the way to cold until it blows cold air and turn it back to warm, and it will be fine for a few minutes and start blowing hot again. Vacuum problem? blend door problem? How would I go about trouble shooting this problem?

I have a 2006 F350 6.0L Diesel with about 72,000 miles on it. It has been the best truck ever, but just about two weeks ago it started doing something real strange. While driving, and it seems to only be at slow speeds, (idle or just accelerating), the truck will shut off the engine. And it is always in this order, it will first "pop" all the speakers real loud, then the radio will reset, (go to the AM radio and shuffle through my 6 disc changer) and then the engine will shut off.
Once I bring the truck to a stop and put it into park, it will then start back up with no problems at all. There is nothing I can seem to piece together as to when it will do it other then it seems to only be at slow speeds... Besides that, it is completely random. One day it did it four times, and then it didn't do it for the next few days at all... The only thing that has changed over last 2 weeks is that, the last few times that it has done it, it didn't kill the engine, it still popped the speakers like normal and then reset the radio, but didn't shut off the engine.

I have an '04 EX with 6.0. When braking at highway speeds the rear end shudders until I get the truck slowed down some. Around town speeds of 45 or less the problem is almost non-existent. It almost seems to be hydraulic instead of pads/rotor issue. Wouldn't a warped rotor show up at slower speeds as well? I have some good mechanics around, but have never found a great brake shop that I can trust. Go in needing pads and they try and upsell saying this or that is going out.

I have a 2011 f250 6.2 cclb and it shakes around 70 to 75 mph. Not terribly but enough to annoy the crap out of me. Now I have put new tires on it recently, new Rancho 9900 adjustable shocks, I have it aligned regularly and tires rotated and balanced every 5000 miles or so. I have had two dealerships look at and my local shop and they can't see anything visibly wrong with it.

1999 F-350 7.3 Dually 2wd Front End issues. I think I may have several things going on so here goes. Truck has about 130,000 miles on it . Bought it with 60,000 miles in 2009.
It's always worn the front tires weird but it's gotten a lot worse and it's happening in about 10-15 thousand miles now. It's wearing the tires on both sidewalls like under-inflation but I run 70 lbs in them. I've noticed for several years now that it makes a knocking sound and I feel it in the floorboard, shakes in the steering wheel when I turn to the left only in a corner at speed. (65-70) ...
Now it's started intermittently going into the death wobble at slow speeds like the caster is to negative on it. I'm sure it could use some shocks but I just rotated the tires and I felt no play anywhere. I know when we used to get that bumping in the floor board on older Fords it was a bad radius arm bushing but that couldn't be all of what's going on here. I've done searches on this and it has happened to others but I haven't found a resolution from any yet.

At low speeds, I notice a squeel sound in all four wheels. Ford tells me that it is due to the type of metallic pads they use and is essentially brake dust noise that warrants no repair.
Any after market pads that are good quality for towing heavy loads, yet aren't metallic in composition? For instance, are porcelin pads a good choice.

I bought this Ex a little over a month ago and finally got around to replacing some stuff.
I have a slight vibration between 50 and 60 MPH. The vibration is the same weather I am accelerating, in Neutral, Coasting down (well, a little bit worse when coasting down), in 2WD, in 4WD, turning, going straight, hot or cold.
I have replaced the following:
Rear Driveshaft U-Joints
Tires and Rims
Upper and Lower Ball Joints
Wheel Bearings
Steering Stabilizer
Cleaned and Greased the Hubs
Greased everything greasable up front
I still have the exact same vibration as when I started. I can feel the vibration in the steering wheel as well as in the body of the vehicle. I am thinking that it may be in the steering linkage. If there is a loose joint then the wheels would be allowed to jiggle a little bit. I am at a loss. What else should I check?
Also, When doing the ball joints, I noticed that the tie rod ends were quite stiff. How stiff should these be? I can't move them by hand, but they will move a little bit when moving the free end of the tie rod.
I am taking it in for an alignment on Friday, and if I can't figure this vibration out, I might have them take a quick look into it. Would a stuck slide pin in the front brakes do this? Both sides on my truck are seized at the current moment.

I have an 2011 F250 gas. I get what feel like a wheel vibration at 48 to 50 mph. It then go as you go up in speed. Comes back as you go down in speed at about the same range. Had it at the dealer for a month they but new tires and one new wheel on the truck. Same problem. Moved up to Ford. The sent me to another dealer. Ford now tells me that this is a problem that exist in the truck and there is nothing they can do.

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.
