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.

    9. Tighten
    Tighten the nut to 153 N·m (113 lb ft) while rotating the wheel 360 degrees in both directions. This rotation will correctly position the bearings.

    Important: Always back off the nut 1/4-1/6 turn. This adjustment should result in bearing end play of 0.025-0.200 mm (0.001-0.008 in).
