Wheel End Speed Sensor Repair
Front Axle Speed Sensor
The front axle speed sensor is located on the inboard side
of the steering knuckle.
CAUTION: Block wheels before beginning this procedure.
Follow all standard safety procedures, outlined by, but not
limited to, the General Precautions listed on page 13 of
this document.
CAUTION: Do not work under a vehicle supported by a
jack.
Removal
1. Disconnect sensor cable from harness.
2. Remove the sensor from the sensor bushing. (Do not
pull on cable.)
3. Remove the speed sensor friction sleeve from the steer
knuckle.
Installation
1. Install the sensor bushing with the flange stops towards
the inboard side of the vehicle.
2. Apply high-temperature silicon-based grease to the
body of the speed sensor.
3. Push the speed sensor completely into sensor bushing
by hand until it stops against the tone ring. The speed
sensor is properly installed and adjusted when it is
touching the tone ring.
NOTE: The speed sensor must slide freely in and out of
the mounting sleeve bore. Operating the vehicle with
seized components will damage the speed sensor and
the tone ring.
4. Test the installation.
5. Check the cable routing and connections.
6. Clear the trouble codes. A 17•12 trouble code will
remain in the system until the vehicle has been driven.
7. Test drive the vehicle and verify that the ABS warning
lamp operates properly.
