What parts do I need to fix front thrust arm mounts cracking?

Do I need new thrust arms or just mounts? What is the difference between control arms and thrust arms, if any? They look the same to me.

You can determine whether you need thrust arm bushings only, or need to replace the whole thrust arm only after a tear down inspection of the ball joint end of the arm. The difference between control arm and
thrust arms are although they look similar, they are shaped differently and perform different task in positioning the wheel.
