Remove the wheel speed sensor bolts with an 8mm Allen wrench. Gently, twist and lift the sensor out. It’s very common for these to break when you remove them, and they are about $15 each. It’s easier to snake the sensor through the backing plate once the unitbearing is loosened from the steering knuckle. The spindle nut required a 35-millimeter socket (a 13⁄8-inch socket works as well). Next, from the backside of the steering knuckle, use a 13mm socket to remove the bolts that thread into the unitbearing. Do not beat on the unit bearing to break it free from the steering knuckle or you can damage it.
