For those who missed it, Marco Andretti's truck lost it's entire rear axle assembly while coming down the front stretch at COTA. Bozi did a great job at explaining what all has to go wrong for that to happen, and what he thinks caused it. With what I learned from my trip to Charlotte, I bet the control arms it was mounted to were used and sold to his team from another team.
