I have a popping sound coming from under the truck in the area of the transfer case and transmission. I suspect a u-joint is going bad because the sound only happens under hard acceleration. As well there is no stalling or jerking related to the popping. There is damage to the frame rail that passes underneath the transmission and transfer case but I could not find any scarring or indication of damage to the transfer case itself.
