My water pump bearing failed, melted and heated up the shaft enough to twist off the pulley. Didn't leak a drop of coolant before or after the failure or give any sign there was a problem. Did tear up the belt and bend the tensioner but that's it .Happen on 95 in GA traveling from NJ to FL with 2k lbs in the bed and loaded 10K trailer. I was able to get a tow to an empty lot at the next exit and get the parts and fix there. This one one hell of a roadside task LOL. Lost about 8 hrs but did complete the last 4hrs of the trip with no problems. I never saw one fail like this so i wanted to share.
enjoy.
