[Vwdiesel] Spalling on Outer CV Joint

[Gavrik Peterson]

Years ago, when I got my first Rabbit, I would replace any outer CV
joint that had spalling (pitting) on the surface of the groves that
the balls run in.  I did this because the manual recommended replacing
joints with this kind of wear.  Later, I noticed that spalling could
appear on a joint that showed no other problems, way before the
expected end of life.  Because of this, I have reused joints that show
this spalling.  This seems to have worked out in that I have yet to
have a joint fail or become noisy.

What is the level of wear that indicates that a joint should be
replaced?  Or, is it ok to use the joint until it becomes loose or
noisy? 

Because I have the drivelines out, and am renewing them, I am
motivated to ask what the experienced folks do.  Should I reuse that
joint with spalling on 3 out of the 6 groves which is otherwise free
of play and works smoothly?  Or should I replace it?

I am also wondering if other people have experienced outer joints
showing early spalling as I have?
