I got a HF preparing my car for the swap im going to do later

anyways I was taking off some of the bolts that are castle nuts, the 3 on the whole arm. and I got the pins out and the nuts out, (driverside) I got the middle one out that is on the right, but the bottom one (i think its the ball joint) wont pop up

any suggestions on out to take it off? cause we tried hammering it out but that just messed up the thread and that was a biotch to get back on (use my car for daily driving), so sorta need your opinions on how to take it off, it came off before cause I added springs on my car, but didnt do it then because I got these DA brake hub and knuckles yesterday for free.

and any instructions how to swap the DA MC, brake booster and port valve?

 

to get it off withoput a ball joint remover, just loosen the castle nut and turn it all the way down untill the end of the castle nut is fluch with the end of the threads on the bolt ( so u dont mess the threads up hitting it) then get a hammmer and hit up on it from the bottom and itll pop out, then push down on ball joint as you take the castle nut off and done. ( i done it yesterday).
