Wheel Speed Sensor Encoders
The wheel speed sensor encoders are magnetized rings used to create a Hall-effect switch when combined with the wheel speed sensor.
On 2WD vehicles, all 4 wheel speed sensor encoders are integrated into the wheel bearing and hub assemblies and are serviced with the assemblies.
On AWD vehicles, the rear wheel speed sensor encoders are pressed onto the rear axle shaft and are serviced with the axle shaft. While the front wheel speed sensor encoders are integrated into the wheel bearing and hub assemblies and are serviced with the assemblies.
