yeah, essentially you get another wheel stud, they're 4 dollars at a mazda dealership. then also you take off the caliper, rotor, and you bang out the old one and pull it from the rear of the HUB, and from the rear of the HUB, you just press in and bang in the new one till it's secure. If your not comfortable doing it - it's a 30 minute job at any repair shop.
