-Use a punch to drive the dent that keeps the axle bolt from moving free of the groove.
-Remove the center cap from the tire/wheel
-Put the tire/wheel back on the car with the lug nuts
-Lower tire back to the ground with full weight on it
-Use a breaker bar with a 36" pipe over it (be very careful when applying that much force to axle bolt; eye protection and know where things will go if the socket breaks or slips)
