Press out the old studs from your wheel hubs or drum to hub combinations and clean the surfaces where the hubs will contact the drums.
Place a new stud in position on the back side of the wheel hub or drum then slide the installation tool over the threaded portion of the stud. The tapered side of the tool will face outward. Use a new left or right hand threaded wheel nut and thread it onto the new wheel stud with the tapered side of the nut seating into the tapered side of the tool.
Tighten the wheel nut against the tool to pull the new stud into place. Use a criss cross pattern when installing the other studs to insure an even installation of the remaining studs into the drum or hub. An impact wrench will speed up the installation.
