I spent the day removing both axles, cleaning the CVs, then
repacked, reversed the axles and re-installed.

The joints looked fine, although I didn't dissassemble them, just
cleaned with lots of paper towel and brake cleaner. Boots were
also fine, so I left them. I only managed to strip one bolt, and that
was during installation, so I was quite impressed... ;-)
After reading the files archive about CVs, I packed lots of grease in
the first side (used nearly all of a long tube - 400g). I know this is
double what is called for, but it didn't seem excessive. I then had to
go the local FLAPS and get more grease - all they had were 90g
tubes at $4 each! I bought two and did the other side by the book,
which leaves very little grease after the joint is filled. I was warned
that I may blow the boots off by using as much grease as I did. I'll
keep an eye on things... (if anyone thinks I will definitely blow the
boots and should fix it now, please e-mail me!)

As for the knocking noise, I still haven't driven it, but the noise is
less noticeable when on jack stands now, but still present. I can
only assume this is due to reversing the joints, since they were
well greased when I started.

Thanks to all who offered advice!
