Rear
REAR WHEEL SPEED SENSORREMOVAL
1. Raise vehicle.
CAUTION: When disconnecting 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.
Fig. 2 WHEEL SPEED SENSOR CONNECTOR:
2. Remove grommet from floor pan of vehicle and disconnect speed sensor cable connector from vehicle wiring harness (Fig. 2).
CAUTION: When removing rear wheel speed sensor cable from routing clips, be sure not to damage the routing clips. Routing clips that are molded onto the brake hose will require replacement of the brake hose if damaged during removal or installation of the speed sensor cable.
Fig. 3 SPEED SENSOR CABLE ROUTING:
3. Carefully remove speed sensor cable from press-in routing clips (Fig. 3).
4. Remove bolt securing metal routing clip to rear of axle and remove sensor cable from metal clip (Fig. 3).
5. Remove secondary (yellow) retaining clip at rear of wheel speed sensor head (Fig. 4).
Fig. 4 SENSOR CONNECTION AT HUB AND BEARING:
6. Push up on metal retaining clip (Fig. 4) until it bottoms. This will release wheel speed sensor head from hub and bearing. While holding metal clip up, pull back on wheel speed sensor head removing it from hub and bearing.
7. Remove wheel speed sensor assembly from vehicle.
INSTALLATION
CAUTION: Proper installation of wheel speed sensor cable is critical to continued system operation. Be sure that cable is installed in routing retainers/clips. Failure to install cable in retainers may result in contact with moving parts or over extension of cable, resulting in an open circuit.
CAUTION: It is important that only Mopar Wheel Bearing Grease be used for the following step application. Other lubricants may cause sensor failure.
1. Lubricate the sensor O-ring with Mopar Wheel Bearing Grease before installation into the Hub And Bearing. If not lubricated, an improper seal may result due to rolling of the O-ring.
2. If metal sensor retaining clip is not in the neutral installed position on hub and bearing cap, install from the bottom, if necessary, and push clip upward until it snaps into position.
3. Install wheel speed sensor head into rear of hub and bearing aligning index tab with the notch in the top of the mounting hole. Push the sensor in until it snaps into place on the metal retaining clip.
4. Install secondary (yellow) retaining clip over wheel speed sensor head and engage the tabs on each side.
5. Route sensor cable under leaf spring along rear of axle. Install speed sensor cable into routing clips on rear brake flex hose (Fig. 3).
6. Install cable into metal routing clip and attach it to the rear axle with mounting bolt (Fig. 3). Tighten mounting bolt to 16 Nm (140 inch lbs.).
7. Connect wheel speed sensor cable to vehicle wiring harness (Fig. 2). Be sure speed sensor cable connector is fully seated and locked into vehicle wiring harness connector.
8. Install speed sensor cable grommet into hole in floor pan making sure grommet is fully seated into hole.
9. Lower vehicle.
10. Road test vehicle to ensure proper operation of the base and ABS braking systems.
