1300-1400 RPM Vibration?

[rvdb]

Hi, First off I am new to the site & appreciate any input, I picked up a 2012 F350, 4x4 CC, LB, a month ago and I am in need of help, I searched the site, asked questions on other threads with no luck.
I have a vibration at 1300-1400 RPM roughly in between 35 to 45 miles an hour, I am sure its driveline related due to how the vibration comes about.
Ford replaced the drive shaft and balanced the exhaust and checked/balanced the tires.
The problem still persist, I was sent out the door per Ford. I have 800 miles on it and really like the truck however I feel this will lead to premature wear of components not to mention when I break it in & start towing 12k lbs.
Questions; has anyone dealt with this, does it get worse or stay the same?
I am very disappointed in this product at the moment, and am frustrated, thanks for your time.

It seems to be somewhat common at around 40-45.

Replace the Steering Stabilizer.... Mine did the same thing and my buddy who is a ford mechanic said to replace the stabilizer, I did and the vibration stopped... Not to say that this will fix your problem, but it fixed mine.... Just something to keep in mind...

Thanks, was it vibrating at a specific RPM? so far, they replaced the torque converter & drive shaft so far and it still does it.I bugs me to think I may have to settle on a new truck that vibrates....

Mine did it when towing backhoe and on the gas... put a larger/heavier duty carrier bearing on drive shaft and mine quit. Bearing was $60. My truck is 2012 F350 Lariat 4X4 CREW CAB DRW now with 13,000 miles. Mine started at around 1200 miles
