UPPER and LOWER C.A. nut's torque specs?

[losthope]

Hey gang! I did a search but didnt find what i need...
I was wondering if anyone knew how much im supposed to tighten these ?? specs? Im finishing up what the previous owner started and have never replaced these on any vehicle before so need some help??


And since im asking dumb questions i assume the only way to get the lower arm ball joint out and replaced back in is to have them pressed in and out?? or is there a easy DIY way at home in a driveway?

I see the top arm ball joint you have to drill out the rivets holding it in....
