Dave, rubber bushings do not have stiction. They actually twist in deformation, thus no sticking friction that slips loose. Polyurethane bushings are well known for stiction, because they do rotate, and make the various sounds people describe.
Rubber bushings do have hysteresis, but let’s not get into that now.
