The bushings are the rubber pieces on top of the front shock stem.  The
cups are the dished washers that squeeze the bushing and draw up the shock
into the a-arm.  I found the KYB were squeezed down to the point where the
shoulder of the shock below the threaded part of the stem was banging up
against the bottom side of the cup.  I made some thicker bushings out of
some rubber stoppers and the noise was gone.  I had unfortunately thrown
out my VW bushings and cups with my old shocks.
