  6. Inspect the lubricant level.

    Specification 

    The lubricant level should be between 0-10 mm (0-0.4 in) below the fill plug opening.

  7. If the level is low, add lubricant until the level is even with the bottom edge of the fill plug opening. Use the proper fluid. Refer to Fluid and Lubricant Recommendations in Maintenance and Lubrication.
  8. Install the rear axle fill plug.
    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 fill plug to 33 N.m (24 lb ft).

  9. Lower the vehicle.
