  8. Remove the sensor mounting screw (5).
    IMPORTANT: The wheel speed sensor mounts into a bore that leads to the center of the sealed bearing. Use caution when cleaning or working around the bore. Do not contaminate the lubricant inside the sealed bearing. Failure to do so can lead to premature bearing failure.
    NOTE: Carefully remove the sensor by pulling it straight out of the bore. DO NOT use a screwdriver, or other device. Prying will cause the sensor body to break off in the bore.
    NOTE: Do not attempt to remove the stainless steel shim from the bearing assembly. The shim is permanently attached. If the shim is damaged or bent, replace the bearing assembly. Failure to comply will result in diminished sensor and ABS performance.
  9. Remove wheel speed sensor from hub and bearing assembly.
