What to do0 / 2 checked

Slide the front hub onto the . The fit is snug — if it does not slide on by hand, a light tap with the rubber mallet seats it.
Thread the hub nut on and torque to 305-338 (225-250 ). That is a serious number — a standard 12-inch ratchet will not get you there. Use a long breaker bar with a cheater pipe, or a torque multiplier. Once the hub nut is set, drive the dust cap into the front of the hub using either a large socket as a buffer or a flat-head screwdriver and the rubber mallet, tapping gently around the rim.
