Both manufacturers recommended shrinking the bushing cloth with = 50/50 alcohol and water, then heat it up with a heat gun, exercise the = joint, and "voila!" they magically loosen up. They also recommended lubing with = Protek while the parts are still warm.</DIV> <DIV> </DIV> <DIV>At this point, let your conscience be your guide.
