You need to assemble the tire pressure sensor to the valve stem and install the new TORX screw, apply tire soap to the rubber portion of the valve stem, and use a tire valve stem mounting tool to pull the valve stem through in a direction parallel to the valve hole on the rim, mount the tire to the rim, install the tire/wheel assembly on the vehicle, lower the vehicle and learn the tire pressure sensors.
