2-Part Control Arms Question

[69_C10]

Part A - I'm in a frame off project and starting to re-assemble my suspension to my frame. I had my control arms powdercoated. I don't want any squeaks etc when re-assembled. How do I know if I need to replace the shafts of my control arms? Any tell-tell signs to look for?

Part B - How do those shafts come out of the control arms? I'm assuming they screw off of the ends. The powder coater really laid the powder to these and probably are stuck in place. Any particular method of removing\replacing the shafts?

Thanks Guys - I really appreciate you.
