3500 Drive Train Vibes

[Red360]

My 2000 3500 4x4 QC starts vibrating between 52 and 58 mph. You can feel it in the floor board. It doesn't matter if the clutch is in or out or different engine RPM. The dealer has rotated and baleanced the tires, but it still there. Any ideas? Thanks, Scot

Sounds to me like a driveshaft balance problem. If you have a manual transmission
you can usually feel the same vibration
coming thru the shifter.

Mine Vibrates between 1800 and 2200. Seems to be a drivetrain problem, goes away when I push in the clutch. Still looking for an intelligent dealer to send it to.

Red360, you don't say what trans. you have. There is a natural harmonic vibration at the speed you mention when in O. D. , especially when towing something, try running through that speed in a lower gear and see if it goes away. OOOPs, I didn't notice the date on your post, sure it's worked out by now. bg-------------
