  5. Install the rear axle housing cover bolts (1).
    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.

    Tighten 

    Tighten the rear axle housing cover bolts in a crosswise pattern to 30 N.m (20 lb ft).

  6. Fill the rear axle with axle lubricant. Use the proper fluid. Refer to Capacities - Approximate Fluid and Fluid and Lubricant Recommendations in Maintenance and Lubrication.
  7. Lower the vehicle.
