Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Wheel Speed Sensor Encoder Rings
The wheel speed sensor encoder rings are magnetized, toothed rings used to create a Hall-effect switch when combined with the wheel speed sensor. The front wheel speed sensor encoder rings are integrated into the front wheel bearing and are serviced with the front wheel bearing. On single rear-wheel vehicles, the rear wheel speed sensor encoder rings are pressed onto the rear wheel axle shaft and are serviced separately from the axle shaft. On dual rear-wheel vehicles, the rear wheel speed sensor encoder rings are part of the rear differential, ring-gear, backlash adjusters and are serviced with the adjusters.
