This is needed for steering because the outer cv joint center isn't completely coincident with the steer axis.

Okay that makes sense if the CV joint is allowing for this change at the wheel.
So the CV could be a likely candidate for the clunking sound? I'm wondering if the CV part of the axle is what they changed from '12 to '13 resulting in different part numbers then.
I'd like to see someone put in a '13 axle in their clunking '12.
