Does urethane squeak?
In a word, no. Squeaking is caused by high frequency vibrations that can be heard rather than felt. It is usually caused by lack of lubrication, poor installation, incorrect part, urethane that may be too hard for the application. In sway bar mount applications, most squeaking comes from not cleaning the sway bar prior to installing the bushings and not using our “squeak proof” Supergrease! Additionally, all our dynamic application bushings feature grooves or splines to hold in our waterproof, highly adhesive, high temperature and pressure SuperGrease™.
