6.2.1 Ford IFS (independent front suspension)
NOTE : This section applies to the front differentials of Ford
IFS equipped vehicles only.
The Dana 44 differential supplied on Ford independent front
suspension vehicles manufactured since 1983 utilizes a C-clip to
retain one front axle. When an Air Locker is installed, this C-clip
cannot be reused. Therefore a spring is required to be installed at
the outer end of the axle to prevent the axle from floating out of
engagement with the splines.
Insert an automotive valve spring (or spring of similar strength)
inside the outer yoke - spring loading the slip spline against the
inner end of the stub axle. (Fig.24.)
Figure 24.
NOTE : When assembled, ensure that the spring maintains
sufficient pressure on the axle to hold it firmly
against the cross shaft of the differential while the
vehicle is sitting on level ground.
