If these are the same as the ones used to anchor Golf exhaust pipes, I have
used the factory-tool set of wedges to remove/install them.   You need two
wedges for each spring (the two wedges in a set are slightly different),
and although you can do it (on the Golf) with only one set, it is much
easier with two sets.    There was also apparently at one time a tool which
used a screw to expand the spring, but I was told that this tool has been
phased out.
