Inside the Original Jeep Quadra-Trac
Inside the reduction unit is a simple four-pinion planetary reduction setup, very similar to many late-model transfer cases. A few Torrington bearings and a large ball bearing in the rear are all that will wear out, and proper maintenance can keep those parts in good working order. Disassembly is straightforward and consists mainly of removing snap rings and a few bolts. The reduction housing has its own oil supply and needs to be filled and drained separately from the rest of the case. View Related Article
