If you've had it all the time, and you have a vehicle with a two-piece
driveshaft, sometimes shimming the center carrier bearing mount (adds a bit
of angle on the front U-joint, lessens the angle on the rear) can cure this.
I didn't mention this to the OP, because he said it had only recently
developed.

Also, some have reported (Roy here being one of them, IIRC) that a procedure
to "align the drivetrain" has cured this shudder.  This involves loosening
the engine and transmission mounts, driving forward about 100ft., driving
backward the same distance, then re-tighten the mounts WITHOUT moving the
vehicle.  It seems some drivetrains were installed in a slight bind, and
this has been shown to cure some shudder-on-takeoff problems.

Richard - I'd be interested in hearing what you find out.  I have a
2003 I just bought with 33k miles on it - similar situation.  I don't
notice it visibly in the mirror buti can feel it - not quite all the
time, but most of the time.  My gut feeling was directing me towards
driveline in some fashion.  

If you can't post it here, please let me know at

Thanks all, I will start with the u-joints since its easiest and cheepest and
work through the other solutions, thanks for the input. Richard

O.K. dodge guru's figure this one out. Dodge ram 1500 4x4 quad, 100,500 miles
and new balanced tires, brakes and rotors. When initially taking off from
stop, and without touching gas, truck shutters ever so slightly but enough to
see out rear view mirror. As soon as I touch the gas its gone, or if I reach
3-4 mph. It doesnt do it any other time. If I hold the brake and let it roll
at 1-2 mph it will continue to shutter, almost hop. Is it the Torque
converter going bad, something else? The fluid, and filter where changed
(with proper fluid) but no improvement.
