Major Components of The Drivetrain

- Differential: The differential lets wheels move at different speeds. This is important for smooth turns and handling.
How Each Component Interacts Within The System?
Every part of the truck’s drivetrain has a special job. The transmission moves power to the transfer case. From there, it goes to the driveshafts.
This setup gets all four wheels moving. It gives the truck better grip on the road.
