Wheel Speed Sensor Replacement - Rear

Removal Procedure

The rear wheel speed sensor is contained within the hub/bearing assembly. The sensor is not serviceable seperately. To replace a damaged rear wheel speed sensor, the entire rear hub/bearing assembly must be replaced.

Caution

Ensure that the vehicle is properly supported and squarely positioned. To help avoid personal injury when a vehicle is on a hoist, provide additional support for the vehicle on the opposite end from which the components are being removed.
