In situ replacement of front outer CV boots

Hi Rick,

I did not post my resonse to Chris's Qs to the list as I didn't expect the
current level of interest.  Will do so now, after the fact.

I don't know the specifics of the A6 CV joint problems but I suspect that
the snap ring attaching the joint hub to the half shaft is more like that of
the 89 chassis and the auto 44s, that being a round wire snap ring on the
outboard side of the joint hub.  With this configuration it is easier to
remove the hub from the half shaft inasmuch as the hub can be "forced
through" the retaining ring without having to first release the ring.  A
design that is much easier to service.  BTDT on my 90Q.

I do/did not remove the anti sway bar from the lower arm, only dropped its
attachment to the front subframe.  Thus, neither did I compress the spring
to accommodate the sway bar or to reinsert the ball joint into the hub
housing.  Not necessary.

Regards,  Bernie
