Rear
REMOVE1. Raise vehicle on jack stands or centered on a frame contact type hoist.
2. Remove the tire and wheel assembly from the vehicle.
CAUTION: When unplugging speed sensor cable from vehicle wiring harness be careful not to damage pins on the electrical connectors. Also inspect connectors for any signs of previous damage.
Speed Sensor Cable Connection To Vehicle Wiring Harness:
3. Remove grommet from floor pan of vehicle and unplug speed sensor cable connector from vehicle wiring harness.
CAUTION: When removing rear wheel speed sensor cable from routing clips on rear brake flex hose, be sure not to damage the routing clips. Routing clips are molded onto the hose and will require replacement of the brake flex hose if damaged during removal of the speed sensor cable.
Speed Sensor Cable Attachment To Brake Flex Hose:
4. Carefully remove the speed sensor cable from the rear brake flex hose routing clips.
Rear Speed Sensor Routing Brackets And Clips:
5. Remove the rear wheel speed sensor cable/brake tube routing clips. Then unclip the speed sensor cable from the routing clips on rear brake tube.
CAUTION: If the speed sensor has seized, due to corrosion, do not use pliers on speed sensor head in a attempt to remove it. Use a hammer and a punch and tap edge of sensor, rocking the sensor from side to side until free.
Speed Sensor Attaching Bolt:
6. Remove the wheel speed sensor attaching bolt. If sensor head does not come loose, do not use pliers on the sensor head to loosen. Tap sensor head from side to side to loosen.
7. Remove the wheel speed sensor from the rear bearing assembly.
8. Remove the speed sensor assembly from the vehicle.
INSTALL
CAUTION: Proper installation of wheel speed sensor cables is critical to continued system operation. Be sure that cables are installed in retainers. Failure to install cables in retainers as shown may result in contact with moving parts and/or over extension of cables, resulting in an open circuit.
1. Install wheel speed sensor head. Note the plastic anti rotation pin must be fully seated prior to installing the attaching bolt.
CAUTION: Prior to installing the speed sensor head attaching bolt, the plastic anti-rotation pin must be fully seated into the bearing flange.
2. Install the wheel speed sensor head attaching bolt. Tighten the attaching bolt to a torque 12 Nm (105 inch lbs.)
3. Check the air gap between the face of the wheel speed sensor and the top surface of the tonewheel. Air gap must be less then the maximum allowable tolerance of 1.2 mm (0.047 inches).
4. Install the routing brackets attaching the speed sensor cable and brake tube to the rear axle. The rear wheel speed sensor cable should be routed under the rear brake tube.
CAUTION: When installing rear wheel speed sensor cable in the routing clips on rear brake flex hose, be sure not to damage the routing clips. Routing clips are molded onto the hose and will require replacement of the brake flex hose if damaged during installation of the wheel speed sensor cable.
5. Install speed sensor cable into routing clips on rear brake flex hose.
CAUTION: The wheel speed sensor cable connectors for the left and right rear wheel speed sensors are keyed differently. Therefore, when connecting a wheel speed sensor cable to the vehicle wiring harness, do not force the connectors together. If the connectors are forced together, damage to the connectors will occur.
6. Plug speed sensor cable connector into vehicle wiring harness. Be sure speed sensor cable connector is fully seated and locked into vehicle wiring harness connector.
7. Install the speed sensor cable grommet into the body, being sure the grommet is fully seated into the body hole.
8. Install the tire and wheel assembly on vehicle.
9. Road test vehicle to ensure proper operation of the base and ABS braking systems.
