Instructions:
For the front wheel speed sensors:
1. Park your vehicle on a level surface and turn off the engine.
2. Engage the parking brake to keep your car from rolling.

4. Raise the front of your vehicle with a jack and place jack stands under the front frame members to support the vehicle.
5. Remove the front tires and wheels.
6. Clean the surrounding areas of the front hubs where the speed sensors are located.
7. Disconnect the electrical connector from the speed sensor.
8. Use a wrench to loosen and remove the mounting bolt for the speed sensor.
9. Pull the speed sensor out of the hub and discard the O-ring.
10. Apply a thin coat of grease to the new O-ring and install it on the speed sensor.
11. Insert the speed sensor into the hub and hand-tighten the mounting bolt.
12. Use a wrench to tighten the mounting bolt until it is snug.
13. Reconnect the electrical connector to the speed sensor.
14. Reinstall the front tires and wheels.

Test the speed sensors
- Test the speed sensors by driving the vehicle at different speeds and monitoring the speedometer reading
- Check for any discrepancies between the actual speed and the speed displayed on the speedometer
