INSTALLATION

CAUTION: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion Inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems.

Install or connect the following:
1. Wheel hub bolts (255) into the hub/rotor (81).
- Place four washers onto the bolt, then fasten a nut onto the bolt until the nut bottoms on the washers.
- Tighten the nut until the bolt fully seats into the hub/rotor (255).
- Remove the nut and washers.
2. Hub/rotor to the vehicle.
3. Tire and wheel assembly.
- Lower the vehicle.
