This makes the third iteration of this discussion that I've seen.

Cut to the chase bottom line.

To make the CV joints apply thrust through the other set of bearing
faces, swap left to right, inner to outer.
Another way of describing the same thing:
Driver side CV joint has one end pointing left, the other end pointing
right.  Move it to the passenger side without flipping it.  The end that
pointed left should still point left.  Ditto for the right.  The result
will be that the "trailing" bearing faces will now be bearing load and
the former load bearing faces will get a rest.

Somewhere in the archives is my more detailed explaination of just why
this is so.
