Abstract
A vacuum locking hub system is provided for a four-wheel drive vehicle that includes a cartridge-type assembly that allows the vacuum locking hub system to be inserted into the wheel as a cartridge unit for ease of assembly. The vacuum locking hub system has a compact construction allowing it to be substantially received within the wheel hub, thus reducing system mass and unit length.
