I finally got all the tools I need to change my wheels. I loosened the lug nuts, jacked up the car, took out one lug nut, put in a wheel hanger, removed the remaining lug nuts and then I found that there is one lug nut per wheel that is different from the others! A 19mm socket worked for all of the other lug nuts but there is one lug nut per wheel that has a gear like shape to it. I've attached a picture below. What is this and what tool do I need to remove it? Thanks in advance, Jason
