Envoy 2WD L6-4.2L (2008)
NOTICE: 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.
NOTICE: 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.
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.
7. Remove wheel speed sensor from hub and bearing assembly.
Installation Procedure
Important: The new speed sensor will have a new O-ring. Dispose of the old O-ring. Lubricate the new O-ring lightly with bearing grease
prior to installation. You may also lubricate the sensor just above and below the new O-ring. DO NOT lubricate the bore.
