I'm thinking of having some front control arm bushings put in (New Edge prothane) at a labor cost of $400.00 (Ford Dealership) is that insane? No way I can do it myself, it's beyond my skill level. From what I've read here it's quite the job. Then I read the thread where they wear out in 40K, (old thread) is that still the case? I want to do auto-x this summer and from what I read these bushings will really help.
