Hrmmm... I don't know about the bushings. I'm sure after this many miles they aren't in the greatest shape anymore. Although all the reading I've done on control arm bushings usually have inner tire wear assiciatied w/ them being worn out. This has been going on for a while now, and I've made 2 trips back and forth to Phoenix in the past 4 months and after 4K+ miles w/ this symptom, the tires are still worn evenly. But I'm planning on getting new suspension components because it is needed anyways, and I suppose that should help the situation a little bit, maybe... I just don't want to spend $600+ and still go clunk down the road...
