I use 2 rebuilt axels on my westy. Got them from pep boys and one from
advance auto. They came with grease and the joints were pressed onto an
axel. They had two new boots per axel.Cost $99/each.No shipping charges. I
have about 30K on them. No problems. I remember one being an empi joint.Out
of the box, and up onto the flanges they went.  No additional press work at
the local gas  station,or grease,or boots to buy.At the time  I was puttin
money hand over fist into my vanagon, and had to call it quits around this
time.Bought these rebuilts instead of new.If you can get the joints pressed
on for free,reuse the old boots. I have never seen origional boots go
bad.This will keep your cv axel costs way down.I think BD has a joint
kit.You need two per axel+ press work and grease.I think the total per axel
will be about $180/axel when done.

Now, I have heard of large numbers of rebuilt axels coming out of the box
and not working correctly(ie: no complete unobstructed circular motion).
This dosent mean that they are bad axels,only assembeled incorrectly.Got to
remove all the little balls and put them in right-then grease it up.Most
people just send them back.An educational opportunity, it is.This is my
experience w/rebuilts.
