Already read lots of helpful stuff on this -- 3 questions:
(87 2WD hardtop)

1.  The McCafferty article makes much of some subtle shape differences
between sides of the hub and cage, confusing since the old hubs and new
ones don't look quite the same anyway.  Bentley 42.9 says "insert ball
hub ... into ball cage ... position is not important".  Is it?

2. Bentley (same page) says "insert ball hub into outer ring ... chamfer
on inside diameter of ball hub must point to ... larger diameter of
outer ring."  I am not seeing a larger diameter on that outer ring,
looks symmetrical to me.  Would someone clue me about what larger
diameter that's referring to?

3. Old CVs have a single groove on outer circumference that faces out,
i.e. either toward the wheel or toward the transaxle -- the boot caps
attach to the opposite side.  New ones (GKN) have a single groove near
one edge and 3 grooves near the other edge.  Which way should these be
facing?

Thanks y'all.
