Sensor Rotors (Front)

Remove front wheel assembly. Visually inspect sensor rotor serrations for scratches, cracks, missing teeth and warping. If sensor rotor is damaged, replace front axle hub. On Supra, measure rotor serrations at .08" (2.0 mm) from serration edge. Maximum fluctuation allowed, measured at top of 3 consecutive serrations, is .004" (.10 mm). If fluctuation is more than maximum allowed, replace front axle hub.
