Install the wheel speed sensor in the bearing hub and install the bolt. Ensure that the sensor is seated flat against the hub.
Tighten
Tighten the wheel speed sensor mounting bolt to 18 N.m (13 lb ft).
24.
Disconnect the front wheel speed sensor connector and place a digital volt meter (DVM) across the terminals of the wheel speed sensor connector.
Rotate the bearing at approximately one revolution per second. The minimum reading should be at least 350 ACmV's. If the reading is less than
350 ACmV's the wheel speed sensor must be replaced. Follow Steps 12-15 for instructions on replacing the wheel speed sensor. This step must be
repeated after the new sensor has been installed.
Notice:
Whenever the brake rotor has been separated from the wheel bearing flange clean any rust or foreign material from the mating surface of the
rotor and flange. Failure to do this may result in increased lateral runout of the rotor and brake.
Important:
If the rotor was removed using the jack screw method, you must ensure that the hub flange is free of nicks or marks caused by this procedure.
Remove all raised nicks or marks before installing the rotor.
25.
Align the rotor to its original position on the hub and install the rotor.
