Budgie:
Front propshaft.
Unless you've got a cardon/cardan/cardin (whatever they're called) type then you'll get vibration from it because of the angles that the prop is trying to work at.
Normally the front prop will have the two UJs working at about the same angle so they balance each other out. With a lift then the transfer box UJ is working at a greater angle than the Diff end so, even with a wide angle prop, you'll still get the vibration.
