The original equipment front CV driveshaft used on 1975-1/2 and all 1976 to 1993 Dodge and Plymouth full size 4x4 models used a Saginaw Double-Cardan Constant Velocity joint at the transfer case end and a slip joint mounting a Detroit Universal internal c-clip universal joint at the axle end. The CV parts remained unchanged over the entire 18-year production run, however, the slip joint will vary after 1985 and the front universal joint changed in 1993 for trucks powered by the Cummins Diesel engine.
