If the rubber material is supple, I use a combination handle and a Kimball
Lost Motion Regulator tool to adjust while supporting the lower area from
twisting.  If they are not supple, I make no attempt to adjust.

Since it's been a while for me to do a set, my memory says I let the rubber
crumble to get to the square nut.  Then I use a combo/socket set to undo
the square nut while supporting the lower area.  Then, clean up the mess.

Then I use the combo/Kimball tool to put the new parts back on while
supporting the lower area.  The parts aren't cheap.  I don't recall using a
fast method.  Seems like it's a 2-3 hour job.
