Hmm, that doesn't make much sense to me.  CV stands for constant 
velocity, so the angular momentum of the shaft stays relatively 
constant, instead of the sinusoidal loading of u-joints.  These joints 
have worked pretty well in axle shafts for now about fifty years.  
Providing that there's nothing amiss in the design or manufacture or 
torque specs of the specific CV joints used in the newer propshaft, I 
don't see any problem with them.  If anything, they should smooth out 
the irregular loading on the pinion.  And, if the linear displacement of 
two CV joints is the same as the splined driveshaft, that eliminates the 
splines.

Nope, doesn't make sense to me.


Cheers.
