We all know upper ball joints are easy to change, but the lower ones
on my project van were shot also. I decided to see if I could do it
without the help of a machine shop or fabricating any tools.
I was able to accomplish the task with two expensive yet "free"
loaner tools from Canadian Tire. I'm pretty sure these loaner tools
are also available from Autozone in the US.
I don't know if this procedure (and tools) will work on 85 up
Vanagons (or Syncros) but I'd imagine they will. Perhaps another 2.1
person can report their findings?
