Most likely you just upset the apple cart. Our Jeeps are not sports cars but we drive them like it. I myself push the hot Rice cars on the on and off ramps. Why just cause I like to feel the G Forces. Sometimes I get a bit of a shake when I am really cooking it. I would imagine if your turning in and then downshifting load/unload cycle, while your hitting the pothole it could make some items bend and flex.
