46. Final Drive Assembly Disassemble



Final Drive Assembly Disassemble





1. Remove the differential pinion shaft retaining pin (704). Use a pin punch.





2. Important: If the pinion gears are removed, place the final drive carrier into a clean transmission oil pan in order to prevent losing the needle bearings.

Remove the differential pinion shaft (703).





3. Important: The snap ring (57) is not reusable. Discard the snap ring (57).

Remove the snap ring (57) from the end of the output shaft (94).
4. Remove the output shaft (94) from the differential carrier (702).
5. Remove the final drive sun gear (115).





6. Remove the differential pinion gears (707) and the thrust washers (706).
7. Remove the differential side gears (709) and the thrust washers (708).





8. Remove the final drive carrier spiral retaining ring (701).





9. Important: When removing the pinion gears, note the orientation. You must install the pinion gears in the same direction in which you removed the pinion gears. If you install the pinion gear upside down, the change in set wear patterns will cause a noise condition.

Remove the four planet pinion pins (714).
10. Remove the four pinion gears (711).
11. Remove the pinion thrust washers (710).
12. Remove the needle roller bearings (712).
13. Remove the needle bearing spacers (713).
14. Remove the final drive sun gear to carrier thrust bearing (700).





15. Inspect the needle bearings (712), the thrust washers (710), the pinion gears (711), and the planet pinion pins (714) for excessive wear. Polishing is a normal condition for the pinion pins and the needle bearings.
16. Inspect the pinion shaft (714) for spalling or for wear.
17. Inspect the thrust washers (710) for wear and for cracks.
18. Clean and dry the final drive carrier and the final drive components.
