what is the correct kit to use when I replace my upper/lower ball joints?

the first and 4th itms in the list are for 2wd, and I have a 2001 Supercrew 4x4

thanks for the help.

 

does it pull to either side now? if not you shouldn't need to
change camber/caster,from the factory it should have plates that the upper control arm bolts go through that are not adjustable so the bolt only go back in one way, if it does that last kit looks like what we use, just a new bolt with eccentric washers, allows you to adjust upper control arm to change angles
