Attributes:
• Prevent the entry of contaminants, such as dirt, dust, and moisture.
• Prevent tire scrubbing or binding during turns.
• Ensuring efficient power transmission to the drive wheels or tracks.
• Providing stability and maneuverability.

Applications:
The Powertrain Final Drive is a component in transmitting torque from the engine to the wheels, enabling the vehicle to move and providing necessary traction.
