A transfer case housing includes a single-piece casing forming an interior compartment provided with an access opening for assembling components of the transfer case, and a casing cover member for closing the access opening. The casing is manufactured as a single-piece casting wherein bearing bores could be machined into the unitary single-piece casing. The interior compartment is adapted to house an appropriate torque transfer mechanism, such as constant four-wheel-drive, or "on-demand" four-wheel-drive, providing rear or front wheel drive (two-wheel-drive mode), or four wheel drive (four-wheel-drive mode), controlled automatically or manually by a vehicle operator.
