Will this work on both inner and outer tie rod ends?

This is a mechanical leverage tool, not a pickle fork. It applies gradual pulling force rather than impact, which is gentler on the stud and knuckle. Many techs prefer it for that reason, but both methods exist in the field.

What hand tools do I need to use this?

You'll need a wrench or socket to loosen the castle nut, and basic hand tools to position and operate the removal tool itself. No power tools required — this is designed for manual operation.
