Thanks for the info from everyone.  Since my van is my daily driver (weather not great for the motorcycle), I just wanted to have some idea of time and resources needed.

Fortunately, I am able to get the nuts/bolts loose okay  My  main reason for attacking this, is that I have never been able to get the front end set up properly with the proper angle (camber?).  Basically, I run out of adjustment, so the inside of the tires have a tendency to wear, despite toe-in/out, etc.  The right side has always been  a little worse than the left.  I'm hoping the bushings will help with this.
