    Simple physics my friend... Your truck is lowered, so there isn't as much play room under the body. Your transfer case, along with the transmission and motor are bolted to the frame, and while mounts are used, they to torque some when you stomp into it raising one side of the transfer case up. The front driveshaft comes out of the drivers side of the transfer case, while the main driveshaft is the pivot. When you make a sharp corner, the body starts rolling on the frame because of the immense centrifigual forces are driving the body towards the outside of the turn. So, when you turn hard to the left while stomping on it, you have several things working to drive that transfer case into the cab with you, and all are the result of something you've done or are doing, be it lowering it, or stomping on it while trying to turn left...

    i agree with above---check your mounts and see if any are bad.or swap to solid mounts or get a race car and race you 4x4.......mike
