With vehicle raised and supported under lower control arms, measure amount of bearing preload using a pull scale hooked on hub bolt. Preload should be 1.3-2.4 lbs. (B1600) or 0.9 - 2.2 lbs. (all other models). If not to specifications, adjust by tightening spindle nut until correct bearing preload is obtained. Align slot of spindle nut with hole in spindle and install new cotter key.
