Hey Guys I need help
I have been chasing a fine vibration in my F250 2004 Super Duty 4x4 since I bought it in 2006. Present mileage is a nominal 58,000. Doesn't seem to be in the steering wheel. It happens wether its in drive or I slip it into neutral. It has New Tires, New Carrier Bearing, New Ujoints front and rear, both driveshafts rebalanced, replaced front hubs and I even tried installing 1/4 inch shims above the carrier bearing maxing out at 3/4 inch per the shop bulletin. The vibration still does and has always come in about 50-55 mph. Pretty much a stock truck. It is a high speed fine vibration.
What am I missing?

tie rods, bent wheel, drag link, ball joints, pitman arm, stock steering dampner is shot...

These shouldnt be problems with that low of miles but those are things to check

This truck has had it since I bought it. Two completely different sets of tires and wheels. The tie rods been replaced, drag link replaced, ball joints replaced, pitman arm and stock steering damper check out fine. Since I have been all over the front end I will move to the back. Definitely no vibration through the steering. I have read that the large damper on the rear driveshaft can be removed and improve things. So for right now no improvement but if I figure it out I will post the answer in big bold letters.

Hello, I have a similar problem. I have a 2005 F350 Fx4 supercab short bed 3.73 gear ration automatic manual 4wd 6.0 of course. A while back i took truck to shop to have tires rebalanced and rotated they told me i had a bent rim so i chalked the vibration up to that. Now i hauled a bobcat the other day and the vibration got twice as bad so i took truck to shop bought a new rim had the bad one swapped out rotated and rebalanced all the tires again and still have the vibration. The vibration is in the rear, with no tires/wheels on the truck jacked up by the pumpkin i still have the vibration. The hubs checked out good, and there were no tires, wheels, rotors on truck so that eliminated that being the cause. I pulled the drive shaft today and the u-joints feel ok, i dont feel a bind at all in any of them. I re greased up the slip yoke at the rear end and made sure it slid smooth. The vibration is between 45-60mph under 45 its fine and over 60 seems fine, even in neutral it does it. Im thinking about having new u-joints put in drive shaft and having it rebalanced all as one unit and seeing what that does? i have no up and down play at the input of the rear diff. and maybe a tiny bit of up and down at the transfercase but very minimal. what do you guys think? thank you very much. if anybody has had this problem and fixed it please let me know e-mail [email protected] or even call 3307157052. I need to get it fixed, it is driving me bat **** crazy lol. thanks again.

I have the same/similar vibration. Mine is at 39-42 mph, accelerating or decelerating, and is too fast to be anything but a driveshaft. I get a second vibration at 49-52 mph that can only be described as the rear of the truck hopping. There is a little tire vibration mixed in at different speeds but the two vibes above are very consistent. I have measured angles at both the output of the transfer case and the pinion on the rear axle, they are within 1/2 degree of one another. What I have discovered is that it looks like my center bearing needs to move up. not down. Using the angle finder each half of my shaft is pointed down ever so slightly towards the bearing. In looking at my truck it looks like a tail dragger and I am currently wondering if lifting the rear of the truck with either F-350 blocks or air bags will change the angle of the shaft just enough to smooth it out. I'll post it if I get it straightened out.

That's good investigative work. Lets us know the outcome. I have an appointment tomorrow to have the pinion seal changed and the driveshaft changed under warranty at Ford dealer. I'll let you if that helped my truck.

Hello, So i jacked the truck up on jack stands again and put her in drive to watch the rear wheels and everything to see what was going on and something caught my eye. I got close to the wheel that i thought was giving me the problem and sat my hand on top of the brake caliper and noticed it was moving in and out quite a bit. So i thought that possibly i had a rotor that was all messed up. I have been meaning to replace them anyways so i bought new ones and still doing the same thing. I have narrowed it down to either the drivers side axle or hub. The way that it was moving up and down there are only so many pieces that would cause that to happen. so tomorrow i am hoping to be able to take bolts for axle out and slide axle part way out to be able to spin the wheel around by hand and see if my caliper is still moving in and out, if not i have found my culprit. I will let you guys know, but that is my thought, almost guarantee that the axle is bent.

If you pulled the shaft halves apart and did not get them back together correctly then your shaft is out of phase. The front joint and the rear joint should be 90* out from one another. Check the shaft for any factory markings such as arrows or paint marks to help you out. Do a search for drive shaft phasing for more/better info.

Like I said earlier, I brought my truck to the dealer and they said it was my driveshaft. So they replaced it, the whole thing, brand new. Well that must have been it because the vibration is gone, drives nice and smooth. $1,100.00 just for the driveshaft is what the service lady said, almost $1,500.00 all said and done including a pinion seal. All covered under warranty, thank god. Now I don't know if it was a bad u-joint or two or a weight fell off or maybe the slip spline, but it's fixed.

Everything was marked prior to pulling it, I am thinking maybe a rebalance might be in order. I also did not used ford parts, I put in greasable u-joints. But that shouldn't change the phasing.

Peel all of the remaining decals off and go for the clean look. Other than that there is have stickers made, or cough up the coin.

Change the entire driveshaft with a new one, maybe? If you still have a warranty than I'd go that route. It work for my vibration, nice and smooth now.
