Installation Procedure

NOTE: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

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.

Install sensor into the hub and bearing assembly (6).
Tighten

Tighten the sensor mounting screw (5) to 18 N.m (13 lb ft).

IMPORTANT: The new sensor has new mounting clips already installed on the wire. DO NOT reuse the old clips.
