My control arm bushings need to be replaced, since I don't track my car, but I do live in the pot hole capitol of the world, should I get aluminum control arms with the updated/stronger ball joints? I ask this because the 1991 m3 came with aluminums, as did the E36's. I've read that the control arms should be replaced every 2-3years,well at least the bushings. It's kind of scary when you don't have control of your steering starting at 60mph and above. I think everyone should have there's inspected during their next maintenance. I'd hate to see our cars resting on a horizontal tire. By the way this happens often in this city.
