Front Wheel Speed Sensor: Installation
This procedure is for the removal and installation of one of the two front wheel speed sensors.
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 article may result in contact with moving parts and/or over extension of cables, resulting in an open circuit.
- Connect the wheel speed sensor cable connector to the vehicle wiring harness. See Figure.
- Install the speed sensor cable assembly grommet into the front inner fender. See Figure. Install speed sensor cable grommet retainer/routing bracket on the inner fender of the vehicle and install and securely tighten attaching bolt. See Figure.CAUTION: See Figure. 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 in Fig 1. If speed sensor cable is not routed in this direction it will rub against the tire or wheel, damaging the speed sensor cable.

Install and tighten routing bracket mounting bolt to a torque of 12 N.m (105 in. lbs.)
- Install speed sensor head on steering knuckle. See Fig 2. When installing speed sensor head on steering knuckle, apply a small amount of grease on speed sensor locating pin. See Fig 2. 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 N.m (55 in. lbs.).
