For what it's worth, my personal experience has been that bad upper ball
joints clunk and bad upper control arm bushings squeak (for lack of better
words). I've heard of worn ball joints separating catastrophically in
certain instances (hitting a pothole, etc.), while on the other hand I've
seen upper control arm bushings make noise for quite some time but
otherwise otherwise not cause a problem (other than driver-irritation). Of
course, your mileage may vary. At 180k miles, replacing both may not be a
bad idea if you're planning on keeping the van a while, although it also
may not be absolutely neccessary.
I do have a deal going on right now on German upper control arms, as well
as the bushings alone and German ball joints. Won't waste bandwidth with
specifics, but of coure you can always e-mail me directly.
