Hi All, When I shift from 2wd to 4wd (high range or low) the vehicle has a low thumping vibration that seems to come from the right front. The best I can describe it is like the passenger front wheel is severely unbalanced. If I try and accelerate, the shaking gets pretty violent and when I let off the gas slowly I hear a gear on gear grinding noise. When I drop it back to 2wd all it well. Can someone describe what is wrong with it before I take it to a dealer to get looked at? Thanks in advance. whenindoubt
