Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to prevent electrical shorts.
Allow the vehicle to cool if it has been recently driven.

2. Remove the Wheel

Tools Required: Jack, jack stands, lug wrench.
- Safely lift the vehicle using a jack and support it with jack stands.
- Remove the front left wheel using the lug wrench.

3. Replace Wheel Speed Sensor

Tools Required: Ratchet and socket set, torque wrench.
- Locate the wheel speed sensor on the front left wheel hub assembly.
- Disconnect the wiring harness from the sensor.
- Remove the retaining bolt securing the wheel speed sensor using the ratchet and socket.
- Carefully pull the old sensor out of the hub assembly.

4. Install New Wheel Speed Sensor

Insert the new wheel speed sensor into the hub assembly.
Secure it with the retaining bolt and tighten it to the manufacturer’s torque specifications (typically around 8-10 Nm, but check the specific manual for your model).
Reconnect the wiring harness to the new sensor.

5. Reinstall the Wheel and Reconnect Battery

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts to the specified torque (usually around 110-120 Nm).
Reconnect the battery.
