  • Lift the vehicle using a jack and secure it with jack stands.
  • Remove the lug nuts and take off the left front wheel.
3. Replace the Wheel Speed Sensor
  • Tools Required: Ratchet and socket set, torque wrench.
  • Locate the left front wheel speed sensor mounted near the brake rotor.
  • Remove the retaining bolt and carefully pull out the old sensor.
  • Install the new wheel speed sensor in reverse order, ensuring it’s securely seated.
  • Torque the retaining bolt to the manufacturer's specifications (typically around 8-10 lb-ft).
4. Reconnect Wiring
