A generic tie rod separator will work for all of the balljoints in the rack.
I really do not like the 'pickle fork' type because they do so much damage, but I suppose that is ok if they are being replaced.
The '2-arm puller' type of separator is very effective, and does no damage to the boots.
This rack bits are a good DIY project. Try to get the alignment close enough to drive to the alignment shop by marking everything before disassembly.
The Control arm rebuilds are a bit more involved. I have participated in rebuilding 6 of them this year, and now have the process down to a science, but I would not classify this as an easy job.
