REMOVAL
1. Pull the wiring harness connector off.
2. Remove the RABS sensor hold-down bolt and remove the RABS sensor from the rear axle housing.
INSTALLATION
1. Clean the axle mounting surface. Use care to prevent dirt from entering the rear axle housing.
2. Inspect and clean the magnetized RABS sensor pole piece to make sure it is free from loose metal particles that could cause erratic system
operation. Inspect the RABS sensor O-ring for damage and replace if necessary.
3. Lightly lubricate the RABS sensor O-ring with motor oil. Align the RABS sensor bolt hole, and install.
NOTE: Do not apply force to the plastic RABS sensor connector. The RABS sensor flange should slide to the mounting surface. The air gap
setting is between 0.127-1.14 mm (0.005-0.045 inch).
4. Install the RABS sensor hold-down bolt and tighten to 34-41 Nm (25-30 ft. lbs.).
5. Inspect the blue RABS sensor connector seal and replace if missing or damaged. Push the connector on the RABS sensor.
