You find it?
Jack up the drivers rear.
Go under from rear end to the drivers side of the front of the rear end.
You will be able to look from the front of the differential towards the rear and see the sensor. You will have to reach it via the passenger side of the driveshaft/differential. Using your left hand, unplug the harness and just use a quarter inch drive 10 mm socket to remove the bolt which will not be visible because it’s behind the sensor.
