Not to be a smart alec, but a tie rod remover. It's sort of a "C" shaped device , with a fork on one end, and a forcing bolt on the other. Works every time for me.
An alternative is to give the <u>side</u> of the steering arm a sharp whack with a hammer while prying under the tie rod end. Often this will pop them loose. A last resort would be the "pickle fork".
