  2. Place a thrust washer (710) on the bottom of the planet pinion (711) in order to retain the bottom row of needle bearings.
  3. Use J 36850  or equivalent in order to aid in the assembly and in order to keep the needle roller bearings (712) in the race. See Special Tools .
  4. Install the needle roller bearings (712) one at a time into the planet pinion (711).

  5. Install the sun gear to final drive carrier thrust bearing (700) onto the final drive carrier (116). Retain the thrust bearing with J 36850  or equivalent. See Special Tools .
    6. IMPORTANT: Assemble the pinion gears (711) in the same direction that you removed the pinion gears in order to prevent noise due to changing the gear wear pattern.
  6. Assemble the pinion gear thrust washers (710) and the planet pinion gears into the final drive carrier (702).
  7. Install the planet pinion gear pins (714) into the final drive carrier (702) in order to retain the planet pinion gears (711).

  9. Assemble the thrust washers (708) onto the differential side gears (709).
  10. Install the differential side gears into the final drive carrier (702).
  11. Assemble the thrust washers (706) onto the pinion gears (707). Retain the thrust washers with J 36850  or equivalent. See Special Tools .
  12. With the thrust washers (706) attached, install the pinion gears (707) into the final drive carrier (702).
  13. Rotate the pinion gears (707) into position, and install the pinion shaft (703) through the final drive carrier (702) and through the pinion gears (707).
  14. Position the pinion shaft (703) in order to allow installation of the retaining pin.
  15. Install the retaining pin (704) through the final drive carrier (702) and through the pinion shaft (703) in order to retain the pinion shaft (703).
