I don't know what happened, but at 80 km/h I heard a click, click sounds followed by an explosion sound at which point I could see and hear parts flying in every direction while driving down the highway ! I was two minutes away from picking up my four year old son, which happened to be about 150 kms from home, I'm glad he was not in the truck with me. There is nothing left of the transfercase housing,it is gone and most parts inside are gone too ! Never saw anything like it before.

If anyone else had similar problem or reasonable explanation could you share please. Thanks. P.S. I still love my Dodge (s) but they are starting to test my patience.
