I have a 1985 with 180,000 miles.  The front suspension is making
a rattling noise when I go small bumps.  The front suspension has
always made loud thumping noises when I went over large bumps
(e.g. speed bumps).  I have looked for loose items in the front
suspension but it all seems tight.  Steering is also tight.

Is there a known process for determining the source of the rattling?
What are the likely problems?

I have owned the van for a little more than a year so I don't know
of any work done on the front suspension.

Any help to keep my van out of the hands of the local repair shops
would be much appreciated.  Even if I have to go, I can at least know
exactly what needs to be fixed.  I'm beginning to believe that the
repair shops in the area are part of the 500 Club.  No matter what is
actually wrong they find enough work to charge you $500. :-(

Thanks in advance,
