It most definately is NOT the same axle. The spring perches and shock mounting points are completely different.
Internally, the gearing, carrier, and pinion may be the same, and the axle shafts may also be the same. However, the axle housing itself is not.

On the website I posted above it states:
Rear applications have c/clip axles in both 28 and 31 spline. Front applications in late model IFS Ford's and will have 28 spline axles using CV joints.
