Installation
1. Use a stiff brush to clean the stud mounting holes in the hub assembly.
2. Using a hammer, drive the pin into the receiving hole - do not use any lubricants or sealants.

Note: If you do not have access to a press, insert the stud into the socket, then place about four flat washers on the stud and screw on the lug nut. Hold the hub assembly and begin tightening the nut until the stud is seated. Make sure the stud is seated completely, then remove the nut and washers.
4. Install the hub assembly and adjust the wheel bearings (see Section Adjusting wheel bearings).
