Here is a link to the question being asked directly to a Ford engineer when they were on the FTE forums answering questions about the 2015 motor update. They were only there to answer questions about 2015 so the MY is mentioned but is irrelevant as they are all the same.

One other point, even if the axle shafts were smaller, it would not affect carrying capacity of a full floating axle as the axle hub carries the weight not the shaft.
