Someone please help! I was traveling multistate and my jeep began vibrating and before we could pull off the road, parts started flying out from under the car. I was able to retrieve one of the parts from the side of the highway and it is the transfer case. The chain is still in tact, but there is extensive damage on the underside. Does anyone have a clue as to what may have caused this? The noise as I have described it sounded like a coat hanger in a lawn mower. Several parts came off the jeep and the transfer case is not in tact whatsoever. Any advice would be appreciated.
