Tie Rod ends?

Inner or outer? The outer ones are easy, just one bolt and one lock nut, remove the end from the spindle, and twist it off, replacing it with the new one to the same spot to keep the alignment close. Inner is a bit harder, but can be done. Usually if your rack is leaking, it is easier and just a bit more to replace the whole rack and get two new inner tie rods since they are part of the rebuilt rack.
