Vibration when accelerating? In "insane" mode if you floor it the steering while goes BALISTIC!

Floor it and it shakes like crazy. Put the foot down half way and turn a little bit same thing. I'm thinking its 1/2 shaft bent by torque? Only 400 miles on it.

What year and model? The new MS LR has insane mode. Is that what you are talking about?
