The internal wear on the CVs is due to twisting force from the tranny
output shafts fighting against the tire traction. NOT the direction of
joint rotation but rather the direction of forces acting on the
internals of each CV.

The CV joint has an inner and an outer section. Large steel balls
connect the sections. These balls ride in tracks in each section. If you
hold the center section still and try to turn the outer section the
balls will press against one side of track on each section. Now hold the
center still and try to turn the out section the other way. The balls
now push on the other side of the track in each section. These track
sides are the areas of wear in the CVs. Both CVs on the right side of
the tranny have the same internal wear areas. The CVs on the left side
wear on the opposite side of the ball track.
