A transfer case includes a primary shaft, a secondary shaft radially offset from the primary shaft, and a torque transfer mechanism. The primary shaft includes a central channel and an inclined fluid channel. The torque transfer mechanism is configured to selectively transfer torque from the primary shaft to the secondary shaft, and includes a primary sprocket coupled to the primary shaft for transferring torque to the secondary shaft. The inclined fluid channel is associated with the primary sprocket, and includes an outlet that axially overlaps the primary sprocket.

Transfer case with primary shaft having inclined fluid channels

A transfer case for a normally rear wheel drive vehicle having selectively engageable front wheel drive is provided. The transfer case includes a rear housing with a main drive shaft aperture and an aluminum cast front housing threadably connected with the rear housing. The front housing has a main drive shaft aperture axially aligned with the rear housing main drive shaft aperture. The front housing has an integrally formed cylindrical yoke forming an isolation mount for receiving a polymeric isolator allowing for connection of the transfer case with a chassis structure of the vehicle. The cylindrical yoke has a cylindrical preform therein.
