Front Speed Sensor: Removal

NOTE: While the battery is connected, even if the engine switch is off, the brake control system activates when the brake pedal is depressed or the door courtesy switch turns on. Therefore during servicing of the brake system components, do not operate the brake pedal and open/close the doors while the battery is connected.

HINT:

The front speed sensor is a component of the front axle hub sub-assembly. If the sensor malfunctions, replace the front axle hub sub-assembly.
The procedures listed below are for the RH side.
Other than areas where instructions are provided, use the same procedures for the LH side and RH side.
