Final Drive Gearset

The final drive consists of a planetary gearset that transfers and multiplies torque from the planetary gearsets to the differential.
The final drive consists of the following components:
- sun gear
- carrier (part of the differential case)
- ring year

The sun gear is splined to the front ring gear and rear carrier of the planetary gearsets. The sun gear acts as the driving member and the carrier as the driven member. The ring gear is held stationary inside the case using lugged teeth.
