Front Differential Case Assemble W/O E-Locker

Tools Required

    • J 8092 Universal Driver Handle - ¾ in - 10
    • J 25299 Side Bearing Installer
  1. Lubricate the pinion and side gears using axle lubricant. Use the proper fluid. Refer to Fluid and Lubricant Recommendations.

    2. Object Number: 680404 Size: SH
  2. Install the differential side gear thrust washers to the differential side gears.
  3. Install the differential side gears and thrust washers into the differential case.

    4. If the same differential side gears and the thrust washers are being used, install the side gears and the thrust washers to their original locations.

  4. Install the differential pinion gears and thrust washers by performing the following steps:
    5. 4.1. Position one pinion gear between the differential side gears.
    4.2. Position the second pinion gear between the differential side gear directly opposite of the first gear.
    4.3. Rotate the differential side gears until the pinion gears are directly opposite the opening in the differential case.
    4.4. Install the thrust washers.

    Rotate the pinion gears toward the differential case opening in order to permit the sliding in of the thrust washers.

  5. Install the pinion gear shaft.

    6. Notice: Refer to Fastener Notice in the Preface section.

  6. Install the new pinion gear shaft lock bolt.
