Does a transfer case do anything in 2WD?
The transfer case is located between the transmission and front and rear differentials via the driveshafts, creating a two-wheel drive (2WD) or four-wheel drive vehicle. When the transfer case engages the front shaft, which feeds power to the front wheels, the vehicle then becomes a four-wheel drive.
