The splines are on the end axle shaft where it goes into the carrier, in the center of your axle housing. Yes you need to swap some parts to use the 31 spline axles, however I'm not sure what parts need swapped. I'm going to swap in an Explorer axle... I'll get the 3.73 ratio I want, trac loc, 31 spline axles, and disc brakes all at the same time.

You cannot put 31 spline shafts into a 28 spline housing, they are different lengths and the bearing journal is a different diameter in the ends of the axle tubes.

If you want 31 spline rear axles, swap in an explorer 8.8.
