Dave,  If the fluid is really coming out of the center of the rack boot area
(clean it all off and make sure) your problem is the high pressure piston
rod seal which, when leaking, leaks into this area.  This is the cause of
90% of all rack failures.

You need a new rod seal.  A rebuilt rack should have a new seal included in
the rebuild.  The seal can be replaced DIY with a $30 seal kit, but a big
job.  The largest part being the R&R.  BTDT on a "87 5KTQ.  Be sure that
your R&R mechanic knows how to center the steering wheel on the center of
the new rack.
