Thanks for your imput guys. I appreciate it. The 'Parts Geek' recommendation was very helpful (awesome prices)!

I will say again that my question remains. How does one know when you should replace the control arm shafts? I fully understand that the bushings should be replaced, but it appears to me that the bushings are not weight bearing in anyway. They merely hold the grease in the threaded area which is the true pivot point for the control arm. Though I have now decided (with your encouragement) to replace both upper and lower control arm shafts, I am still looking for an answer to this question (I'm anal about knowing the detail).

Again, thanks for sharing your thoughts and recommendations.
