1. Gather Tools and Materials:
- Safety glasses
- Flathead screwdriver
- 10mm socket and wrench
- New speed sensor (OEM or high-quality replacement)
2. Safety Precautions:
- Park the Dakota on level ground, apply the parking brake, and chock the wheels to prevent rolling.
- Allow the engine to cool if the vehicle has been recently driven.
3. Locate the Rear Speed Sensor:
- The speed sensor is located on the rear axle housing, near the differential. Follow the wiring from the sensor to identify its position.
4. Disconnect the Electrical Connector:
- Use a flathead screwdriver to gently pry open the locking tab on the electrical connector attached to the speed sensor.
- Pull the connector straight off to disconnect it.
5. Remove the Speed Sensor:
- Use a 10mm socket and wrench to loosen and remove the bolt holding the speed sensor in place.
- Pull the old sensor straight out of the axle housing.
6. Install the New Speed Sensor:
- Insert the new speed sensor into the axle housing by hand.
- Apply a small amount of thread locker to the threads of the mounting bolt.
- Reinstall and tighten the bolt using the 10mm socket and wrench.
7. Reconnect the Electrical Connector:
- Align the electrical connector with the speed sensor and push it in firmly until it locks in place.
- Secure the connector by pressing down on the locking tab.
8. Test the Speed Sensor:
- Start the Dakota and shift into "Drive."
- Slowly drive forward and backward to check if the speedometer is functioning properly.
- Turn the steering wheel from lock to lock to make sure the sensor is securely mounted.
9. Test Drive and Re-Check:
- Take the Dakota for a short test drive, monitoring the speedometer for accurate readings.
- After the test drive, re-check the speed sensor to ensure that it is properly seated and the electrical connector is secure.
By following these steps, you should successfully replace the rear speed sensor on your 2002 Dodge Dakota.
