I changed the bushings #7 at 115k miles. They were badly worn. I also changed the other arm #10. They were wobbling. It has most definitely resulted in a noticeable improvement to ride quality and stability of the steering. Those ball joints are an absolute bitch to pop by the way ... get ready for a big fight. I couldn't find a ball joint separator big enough to do the job (the lugs are way thicker and longer than any I've ever seen) so I had to improvise.
