The measurement length is not the overall length, but rather the length between 
CV faces, so it ends up being shorter than the axle length. You're correct that 
this makes no sense if you try to measure it between the outside CV races, but 
if you measure it between the inside races then it is fixed and makes sense. I 
believe the manuals have diagrams that show this, but it is never made clear 
what it actually means.

The only reason for doing this at all is to make it clear that you can vary 
this assembled length by installing the Belleville washer in different 
positions. This would yield 3 different possibilities for each assembled axle 
length (both washers inside, one in/one out, both outside.) Even this is pretty 
silly, however, because I think those axles are ALWAYS intended to be assembled 
with the washers inside, so why not just say that?

In all the CV axle assemblies you've worked on, have you ever run across one 
that was intended to be assembled with any of the dished washers outside?
