I just purchased this SUV and I have a question about the part time and full time 4WD. When I have the Jeep in part time or full time and I turn pretty sharply (aka. into a parking space) it starts kicking and shaking. It seems that it happens more violently sometimes than others but it typically always does it. There is no grinding noise or anything like that but it kicks and it doesn't do it in 2WD. Hope someone can tell me if there is a problem and if there is, most likely what it is.
