What you will need

• Replacement ABS sensor.

• Ratcheting wrench

Procedure

1. Park the vehicle on level ground and set the parking brakes. 
2. Loosen the lug nuts but do not remove them yet. 
3. Jack up the front of the vehicle and secure it with jack stands. Do not rely only on the floor jack. 
4. Remove the lug nuts and remove the wheel from the vehicle. 
5. Remove the 10mm bolt that secures the ABS sensor to the steering knuckle. 
6. Remove the ABS wire from the vehicle.

8. Install the new sensor in reverse order. 
9. Install the wheel and lug nuts.

That's it. Replacing the front ABS wheel speed sensor on a Tesla Model 3 is straightforward and takes about thirty minutes.
