Vance,
Plastic items that are under stress or pressure can exhibit what is
sometimes called "cold flow". The urethane bushings that I had
exhibited symptoms of this. The ID becomes oval instead of round (but
the OD remains round). When this happened, the bolt/sleeve is not
longer held securely in the bushing, but instead is free to move around
in the ovaled ID.
