Beast, I don't know how to look out for this, but a former member (Bimati) did a lift on his VX and I thought that he started to chew up drive shafts. It may have actually been the half shafts, and I may be mis-remembering here, but I remember him saying something about the pumpkin angle being critical. If it's tilted to far forward or backwards it starts to screw things up.

I'll try and hunt down some threads about this, but that's what my rusty steel trap of a mind seems to remember.
