Control arm bushings are always bought new.
Stabilizer links' ends and Tie rod ends can be pressed (depending upon the condition), otherwise have to be replaced. New ones are recommended instead of used.
CV joints can be replaced with Kabli ones but new are always better.
Shocks and boots (if needing replacement) should also be purchased new. Kabli shocks are usually problematic. No two used shocks have the same damping effect.
