Start by inserting the new rear wheel stud into the hub flange and rotating it between the hub/bearing and the park brake shoes. After that, add the three washers to the stud and tighten the lug nut by placing its edge against the washers. Drive the lug nut tight so the stud pulls into the hub flange and then confirm the stud is sitting in place. Once done, take out the lug nut and washers and put in the
Brake Rotor and caliper. Afterward, fit the wheel and tire using a new lug nut on any studs you changed before and take off the support while lowering the car.
