The original Ford Dana 50IFS Front Axle uses a combination guide and seal for the Left Axle Shaft Seal and a conventional seal sandwiched between the axle support bearing and axle thrust plate on the right side.
Ford introduced a redesigned Dana 50IFS Twin Traction Beam Front Axle during the 1983 model year that uses a right Differential Output Shaft retained by a C-Clip inside the axle housing. The new design requires the Differential Housing be removed from the left axle beam to service the Right Axle Shaft Seal and/or center axle universal joint. Also introduced was a right Axle Slip Joint protected by a flexible rubber Boot instead of a pressed on Yoke Seal. The Slip Yoke Boot eliminated one of the chronic problems the previous 1980-early 1983 axle had, namely axle shaft spline failure from water and grit infiltrating past the seal.
