Jeep AMC Model 20 Axle Parts
Used in 1976-and-later Jeep CJs, the Model 20 rearend is both strong and
weak. An 8 3/4-inch-diameter ring gear provides strength; weaknesses are
the housing itself and the axle-to-hub retaining method. Converting to
one-piece axles or full-floaters gives this axle better stamina.
