Pulling is usually caused by bad wheel alignment. Although, I have had a few cars over the years that pulled because of a bad tire (tread seperating, or worn too bad on one edge).
Tie rods should be in good working order (replaced?) before attempting an alignment.
Easy to replace. See page 58 & 59 .

You can get a puller(keep forever in your tool box) at any autoparts or such store.
