Replacing Steering Rack?

Don't discount the pressure hose to the rack ... it is not simply a hose,
and it has a sheath that can hide the true source of the leak.  I replaced
the pump on my '88 5kCSQ Avant and found that it was the hose that was the
real culprit.  Replacing the hose is a lot easier than a rack too!  You can
use Dave's method to ID a leaking hose ... squeeze the sheath to see if you
can get fluid to leak out ... that or you can cut a hole in the bottom part
of the sheath near that bulge in the middle.
