Rear wheel speed sensor mounted on the rear wheel hub.
NOTE: For clarity, the rear suspension spring has been removed and the lower shock mount has been disconnected.
To replace the rear wheel speed sensors, you will need a TORX T25 key.
1. Clean any dirt from the sensor wiring harness connector and the hub surface around the sensor installation location.
2. Disconnect the wiring harness connector from the sensor.
3. Remove the screw securing the sensor to the rear wheel hub…
NOTE: For clarity, the work is shown with the hub removed.
4. …and remove the sensor from the hub hole.
NOTE: The sensor is sealed with a rubber ring. Replace the ring if it is too compressed, torn or hardened.
5. Install the sensor in the reverse order of removal.
WARNING: When installing the sensor, precisely align the hole in its housing with the threaded hole in the hub; do not rotate the sensor around the longitudinal axis during installation.
WARNING: The increase in resistance to movement of the sensor should be felt only in the last 2 mm before it is fully seated on the hub. If the sensor fits tightly into the hub hole from the very beginning of installation, remove the sensor and eliminate the cause of jamming (dirt, burr on the housing, etc.).
Front wheel speed sensor is installed in the hole of the front suspension steering knuckle (in the photo it is covered by the front brake disc, so its installation location is shown with a dotted arrow). The sensor is similar in design to the rear wheel speed sensor and is secured in the steering knuckle in the same way. Therefore, the tools, as well as the techniques for removing and installing this sensor, are the same as for removing the rear wheel speed sensor (see above in this subsection).
