Rear Wheel Speed Sensor: Removal
WARNING:
Dust and dirt accumulating on brake parts during normal use may contain asbestos fibers from production or aftermarket linings. Breathing excessive concentrations of asbestos fibers can cause serious bodily harm. Exercise care when servicing brake parts. DO NOT clean brake parts with compressed air or by dry bushing. Use a vacuum cleaner specifically designed for the removal of asbestos from brake components. If a suitable vacuum cleaner is not available, cleaning should be done with a water dampened cloth. DO NOT sand, or grind brake lining unless equipment used is designed to contain dust residue. Dispose of all residue containing asbestos fibers in sealed bags or containers to minimize exposure to yourself and others. Follow practices prescribed by the occupational safety and health administration and the environmental protection agency for the handling, processing, and disposition of dust or debris that may contain asbestos fibers.
CAUTION:
Many components of the ABS System are not serviceable and must be replaced as an assembly. Do not disassemble any component which is not designed to be serviced.
CAUTION:
Only the recommended jacking or hoisting positions for this vehicle are to be used whenever it is necessary to lift a vehicle. Failure to raise a vehicle from the recommended locations could result in lifting a vehicle by the hydraulic control unit mounting bracket. Lifting a vehicle by the hydraulic control unit mounting bracket will result in damage to the mounting bracket and the hydraulic control unit.
CAUTION:
Brake fluid will damage painted surfaces. If brake fluid is spilled on any painted surface, wash off with water immediately.
- Raise the vehicle.
- Remove the tire and wheel assembly from the vehicle.
- Disconnect the wheel speed sensor cable connector from the vehicle wiring harness (Fig 1 ). Remove the clip attaching wheel speed sensor cable connector to the vehicle's body.
- Disconnect the wheel speed sensor cable routing clips running along the brake tube, brake hose and axle trailing arm.CAUTION: When removing a wheel speed sensor from the rear disc brake adapter, do not use pliers on the sensor head. This may damage the sensor head. If the sensor has seized, use a hammer and a punch to tap the edge of the sensor head ear, rocking the sensor side-to-side until free.
- Remove the bolt attaching the wheel speed sensor to the rear disc brake adapter (Fig 2 ), then carefully remove the sensor head from the rear disc brake adapter and vehicle.
