Well, my warranty claim was denied at ford for the replacement of the creaking control arm due to my tubular k member. I dont want to go to tubular A arms because I dont want any increase in NVH. I know the boss 302 control arms are an option, but have any tried to swap the bushings for the prothane ones? Are there any other options to fix the annoying noise the control arm is making? I'd rather not have to spend another $500 on the car right now if I dont have to.
