hi all i need some help

i bought a mk3 2.0 tdci mondeo (52 plate) the other week and after a week the dmf went

so after a day of struggling with it a new dmf, clutch and slave cylinder was fitted!!
now the problem is when i get above around 30mph the front end of the car shakes really bad (and i mean really bad) im sure its not the clutch out of alignment as it was all aligned properly with the correct tools!!

if i dip the clutch it stops? ive read on another site that it may be a drive shaft, now when the nearside drivshaft was removed my dad left the cup in the gearbox and the bearings on the cv joint had fallen off so presuming that these where supposed to be like that i just rested them back where they should have been (im not a mechanic btw) but im pretty sure they were not secure so im thinking maybe they have fallen off again when the joint was put back together??

anyway moral of the story is could this be the problem or is it likely to be something esle?!?!?

any advice would be appreciated!
