Yes get polygraphite when possible. No squeek squeek. fwiw poly is good for end links, sway bar bushings, body bushings, transmission mounts but despite the fact that most use it in control arms or worse other suspension parts its less than ideal as it binds. If possible for suspension parts use the correct durameter (sp?) rubber (factory replacement parts) that gm used in the GN/442/MCSS.
