After climbing just far enough up a fairly unassuming rock to intentionally bend our tie rod, the Jeep slipped and got more than a little bit hung up. We turned the wheel and tried to back up and wham, something popped—our driver-side axle U-joint. It seems that the rear tires were in loose sand and the passenger-side tire was off the ground. The only traction we were getting, and on that tire we were getting a lot, was the driver-side front. Poop.
