No serious do it yourself Vanagon owner with more than 130,000 miles on
the clock should be without one of these!  CV joints, upper control arm
busings, and ball joint replacements are a breeze with this tool.  You
can find them for $130-$150 (Taiwan made,  more than adequate for the do
it yourselfer), and they are worth it.  Shipping will add a bit as you
get farther east, but look for those little tool stores in your area.

I have had one for about 5 years now and have paid for it twice over
between my MGBs and Vanagon.
