Front

This procedure is for the removal and installation of one of the two front wheel speed sensors.

REMOVAL
1. Raise vehicle on jack stands or centered on a frame contact type hoist.
2. Remove the tire and wheel assembly from the vehicle.






3. Remove the speed sensor cable routing bracket from the steering knuckle. Remove the wiring harness sealing grommet retainer and speed sensor routing bracket from the inner fender.






4. Remove speed sensor sealing grommet from the inner fender. Then unplug the speed sensor cable from the vehicle wiring harness.






5. Remove bolt attaching speed sensor to steering knuckle. Then remove speed sensor head from steering knuckle

CAUTION: If speed sensor head locating pin has seized to the steering knuckle, do not attempt to remove speed sensor head by grasping with pliers and turning. This will damage the speed sensor head. Use only the following procedure.






6. If speed sensor head can not be removed from steering knuckle by hand, the locating pin on the speed sensor head has seized to the steering knuckle do to corrosion. Remove speed sensor head from steering knuckle using the following procedure. Remove disc brake caliper from steering knuckle, and remove brake rotor from hub/bearing assembly. Then insert a pin punch through hole in front steering knuckle and tap speed sensor head locating pin out of steering knuckle.

INSTALLATION

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 in this information may result in contact with moving parts and/or over extension of cables, resulting in an open circuit.

1. Connect the wheel speed sensor cable connector to the vehicle wiring harness.
2. Install the speed sensor cable assembly grommet into the front inner fender. Install speed sensor cable grommet retainer/routing bracket on the inner fender of the vehicle and install and securely tighten attaching bolt.






CAUTION: When installing the wheel speed sensor cable routing bracket on the steering knuckle, the speed sensor cable must be looped toward the shock absorber as shown. If speed sensor cable is not routed in this direction it will rub against the tire or wheel, damaging the speed sensor cable.

3. Install the speed sensor cable routing bracket on the steering knuckle. Install and tighten routing bracket mounting bolt to a torque of 12 Nm (105 inch lbs.).






4. Install speed sensor head on steering knuckle. Then installing speed sensor head on steering knuckle, apply a small amount of grease on speed sensor locating pin. Use Mopar, Multi-Purpose Grease or an equivalent on speed sensor head locating pin. Install the speed sensor head attaching screw and tighten to a torque of 6 Nm (55 inch lbs.).
5. Install the wheel and tire assembly on vehicle.
6. Road test vehicle to ensure proper operation of the base and ABS systems.
