One morning, Ryan got in the explorer to drive to school, and he heard a noise while he was driving. He didn’t have time to check it out before school, and then after school he immediately had to go to work. He didn’t notice the noise again until later that night after work, and as he was driving home, it got worse. Finally he pulled over and got out to inspect it. The noise was coming from his back right wheel. Someone had loosened the lug nuts on that wheel so that they would fall off as he drove the car. There were only 2 lug nuts left on the wheel, and the other 3 studs had broken off from the wheel bouncing back and forth when he stopped and started driving. Ryan went around and checked the rest of his lug nuts to make sure that they were tight. A few days later, the same thing happened to the back left wheel, but he caught it quicker this time. In the end, he had to replace all the lug nuts on the back two wheels, and all the studs on the back right wheel.
