Rear Lower Control Arm Install Questions

I picked up a pair of factory Nissan rear lower control arms for my S13 a while back, I have some questions before I attempt to install them. I have searched but wasn't able to find a write-up on this.

1) From my research it seems like everybody is having a hard time taking out the ball joint nut. There doesn't seem to have enough room to get a socket in there to un-bolt the ball joint. Is there a way to remove the RLCA without taking out the axle/up-rights?

2) The factory Nissan RLCA (Part No. 55501-52F0 and 55502-52F0) I picked up from FRSPORT doesn't have grease fittings on the ball joints, does this mean they are pre-greased from the factory?, or do I need one of those grease needles to fill them up?

Any info on this topic would be a great help, when I did my FLCA, the ball joints fought me the whole way...2 broken ball joint tools and ended up smashing it out with a big ass hammer, this doesn't seem like an option since the RLCA has the axle in the way!

thanks in advance guys!
