Very poorly, I would imagine... even the UV inhibited rubber tends to
degrade after a few years. I'll bet there are elastomers that could
be used, but, there might be a better system solution to taking up
misalignment, buffering the slings and arrows of shock loads, and
damping vibrations. The couplings that look like a spring would do
the first two.

At least if you keep the greasy side of the car towards the
road. Erik "on the roof" Carlsson might have different experiences.
