Might as well...

Doesn't rubber harden with age, and aren't those isolators supposed to
be a certain hardness to do their job?

By the way, is stuff like that vulcanized like tires are?

I don't understand why anyone replaces static rubber isolators, such as sub
frame bushings.  Dynamic angular rotation bushings only if the rubber bond
is fractured, usually caused by tightening the anchor bolt at other than the
static ride height.
