engine vibration

i have a 2002 fl1 td4 which is slightly doing my nut at the moment,
there is a lot of engine vibration especially low rev ranges or if i put my foot down it becomes more constant
i so far have changed ball joints lower control arms front drive shafts and 2 of the 3 engine mounts to try and get rid of these vibrations and clunks it developed over the last few months, was wondering if any of you guys have had similar issues that you manged to resolve in the past
cheers guys

I take it from what you have changed that these vibrations only occur when the car is moving, ie if its stationary there is no vibration.

If so, why do you think its the engine?

Have you done a 1 wheel up test and checked the tyres? ...

What sort of vibration is it. Is it from the engine when revved or from the drive train when moving?
