Around midday of November 25, 2021, a clear day with no precipitation, while operating the 2003 Dodge Ram 1500 with about 155k miles on it at approximately 35 MPH, the drive train locked up causing the vehicle to go into a skid and a spin that sent the vehicle into a telephone pole. We could have slid into oncoming traffic, fortunately, we did not. The vehicle was totaled. While loading the vehicle onto the tow truck, responders noted that the axle was sheared at the back due to the rear differential locking up unexpectedly. There was a noise, like a whistle or a whine for a few minutes leading up the incident, but not anything that I would associate with this kind or failure, no grinding, roughness, or clunking.
