recently i have noticed a strange noise which i believe is some part of the suspension binding. i have new ball joints on factory UCA's and factory LCA's. i installed urethane bushings in the LCA's but that changed nothing. i think it could be the spring perch, which is new..er with poly bushings or might be my old stock strutrods which were replaced about 14 years ago now. i hear lots of bad things about ureathane in the strutrods so should i replace them with rubber or aftermarket parts or just make some custom ones? i want to upgrade the front suspension but do not want to lower the vehicle anymore than it is already. i'm at a ground scraping 5"or 6" to the oil pan. all i did was put the 600lb contour coils and 17" wheels with 215/45 tires. can i lower the UCA's 1" and use a 1" poly spring bushing? if i buy the GW UCA's what springs should i get and is there a coil over set up i can use with these? i am pretty good at fabricating so if anyone has suggestions or some custom suspension setups i'd be interested in your ideas. also any ideas as to what might be binding it only happens when i make hard left turns?
