That blummin' "whole car shake" under torque - any more suggestions please?

Symptoms:
When the gas is on, the car judders at a constant frequency (Feels like you're driving over rumble strips - but the car seems to shake from side to side?)

Foot on clutch or off the gas and the vibration disappears immediately. As soon as you tickle the throttle, it comes back and the more load it is under, the "Coarser" the rumble.  If you pick 4th when you'd be better in 3rd, it is worse.
It doesn't travel through the clutch pedal, it is the whole car that shakes. It does it at all speeds, in all gears.

I've had it to two garages who have no idea and are reluctant to start spending time diagnosing for some reason, even though I suggested the drive shafts - can't grasp why?  :o

Any more ideas anyone please?

sounds like a driveshaft or even the flywheel ?

jack it up, take undershield off  and give driveshafts a wiggle.  but just seen that it goes if you press clutch ??  so more likely to be the dual mass flywheel needs replacing.....

I would also suggest outer driveshafts. Use quality replacement as cheap ones would not solve the problem for long.

Inner CV joints can seize and fall apart, jack up car remove undercover then apply up and down movement on shaft.

Dipping the clutch just removes the "Drive" and the wobble - exactly the same as when you throttle-off.
I'm sure it's a drivetrain thing as opposed to the clutch but thanks  :)

SORTED   ;D ;D ;D ;D

Fitted 2 x new complete Drive Shafts and it now sounds like it should and I get to keep all my fillings  :P

Never done the job before but 2 hours on a sunny Sunday morning saw it through from start to finish - thanks to the How To guide on here.

Thanks to everyone for their help  8-)
