The picture does help. It looks like one nut holds the joint on the knuckle and the other the control arm.

After loosening the nuts I guess I will just bang it a few times to loosen the joint and then remove

Should I put in any kind of grease?

Does anyone know the torque?

Anything else I am not considering - beside a good alignment?

Any thoughts on needing to compress the spring?

I can't wait for the CDs to be available
