I saw this the other day, but it looks like you already tried it. Did you notice any difference at all? Personally, i run 37s with 2" lift on beads. I've changed the track bar, tie rod and steering stabilizer. The combination of all the parts seems to help the problem as my steering is a lot tighter, but it's just treating the symptoms and not the underlying problem. I can't believe there's not a recall yet.
