i am going to rebauild the suspension of my 1979 trans am. i looked into polygraphite bushings throught pst. almost 400 bucks compared to 170 from summit. the summits bushings are not polygraphite but polyurethane. i have heard squeaking is the only true disadvantage between the 2. is there any way to stop this with the polyurethane bushings?? is there any type of grease that really works and stops squeaks for the life of bushings??

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
