NV140 Transfer Case - Operation

OPERATION

Full-time 4-wheel drive distributes 48% of the torque to the front wheels and 52% of the torque to the rear wheels. The transfer case center differential divides torque to the front and rear axles, while also allowing the driveshafts to rotate at different speeds to account for front and rear wheels traveling different distances while turning. Given that the drive shafts can rotate at different speeds, the vehicle can remain in full-time 4-wheel drive mode indefinitely, even on dry pavement, without threat of damage to the drivetrain. The vehicle uses Brake Traction Control to modulate the torque from one wheel to another across each axle and the transfer case.
