  1. Install the thrust washers and side gears into the differential case. If reusing the original gears and washers, install the gears on the same side from which the parts were removed.
  2. Install the pinion gears.
  3. 2.1. Position one pinion gear between the side gears. Rotate the gears until the pinion gear is directly opposite the opening in the case.
    2.2. Place the other gear between the side gears. Ensure that the holes in both pinion gears are aligned.
  4. Install the thrust washers. Rotate the pinion gears toward the opening in order to permit the thrust washers to slide in.
  5. Install the shaft and the bolt.
  6. Install the ring gear onto the differential case.
  7. Notice: 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: Always install new bolts. Do not reuse the old bolts.

  8. Install the ring gear mounting bolts.
  9. Tighten
    Tighten the bolts, in progressive steps, to 80 N·m (59 lb ft).
