Drivetrain vibration
I have a 2004 superduty 4x4, V10, 4.30 gear, shortbed and 12000 miles.
I have experienced since new, a vibration in the drivetrain. This only occurs when the engine is cold (summer or winter)and I am pulling a 19' gooseneck w/stump-grinder, tow wieght approx. 6000 pounds.
It does not vibrate when cold and without load or after engine and trans have reached normal operating temps when pulling my load.
I have not taken it to the dealer at this time. Has anyone else experienced similar, if so and it has been fixed what was the cure?

Is this a 4 door, extended cab or regular cab? F250 or F350? Manual or auto tranny?
It sounds like the carrier bearing, which is not to say that it is bad, just a common occurrence - unless it is a very aggressive shudder.
It could also be ujoints - but with 12K miles I doubt it.
Also there's axle wrap. If you have the F350 you have a 4" block, which magnifies the axle wrap. Again, a common occurrence, though.
Just how bad is the vibration or shudder?

F250,Ext. cab Shortbed, Auto.
Occurs on accel. and decel until engine and trans are both at operating temps.
If u joints I should be able to feel some vibration when empty and regardless of temperatures when towing.
very noticeable but does not appear to be in imminent danger of any failure.

How much backlash is in the rear diff? I know it sounds far-fetched, but if it happens on acceleration and deceleration, it's more than likely the diff or the tranny.
But, we can't rule out the carrier bearing. Have you checked to see that the rubber housing is not torn?

Big orn ,remind him about rear dif (ls units) if its on take off !
could be limited slip unit or no friction modifier or not enough friction modifier within the diff from the factory.we know this happens
take in and have them put the wds analyzer on it.
