Replacement (Rear)
REMOVAL PROCEDURE1. Disconnect the Negative (-) battery cable.
CAUTION: Before removing or installing any electrical unit or when a tool or equipment could easily come in contact with "live" exposed electrical terminals, disconnect the negative battery cable to help prevent personal injury and/or damage to the vehicle or components. Unless instructed otherwise, the ignition switch must be in the "OFF" or "LOCK" position.
2. Raise and support the vehicle.
3. Remove the two bolts and the rear wheel speed sensor cover (1) from the differential carrier (3).
4. Disconnect the rear wheel speed sensor electrical connector (2).
5. Remove the retaining bolt and the rear wheel speed sensor from the vehicle.
6. Inspect for the following on the sensor face:
- Inspect for an accumulation of metallic particles, dirt, grease, or other contaminants.
- Clean the sensor as required.
7. Inspect the sensor face for evidence of damage. Inspect the sensor for contact with the toothed sensor ring. The sensor should not contact the toothed sensor ring. Determine and correct the cause of the damage when damage is evident. Replace the sensor if damage interferes with proper operation. Check the axle bearing for excessive wear.
INSTALLATION PROCEDURE
NOTICE: The wheel speed sensor is a tight fit and is to be pushed in by hand. DO NOT force the sensor into position, as damage to the sensor could result.
NOTICE: Wheel speed sensors must be given an anti corrosion coating before installation to prevent corrosion. Do not use grease. Use sealer.
1. Install the rear wheel speed sensor into the differential housing (3).
2. Install the rear wheel speed sensor retaining bolt.
^ Tighten the bolt to 23 Nm (17 ft. lbs.).
NOTICE: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems.
3. Connect the rear wheel speed sensor electrical connector (2).
4. Install the rear wheel speed sensor cover (1) and retaining bolts to the differential carrier (3).
^ Tighten the cover bolts to 15 Nm (11 ft. lbs.).
5. Lower the vehicle.
6. Connect the Negative battery cable.
CAUTION: Before removing or installing any electrical unit or when a tool or equipment could easily come in contact with "live" exposed electrical terminals, disconnect the negative battery cable to help prevent personal injury and/or damage to the vehicle or components. Unless instructed otherwise, the ignition switch must be in the "OFF" or "LOCK" position.
7. Perform the Diagnostic System Check
