Had mine done today. My wife took it in, done in an hour, drives fine. They replaced the (what I would call) drag link. It's the bar that attaches between the two inner tie rod ends. I have replaced both of the inner tie rod ends myself, and each time I had to split the sleeves with a Dremel, and install new ones. Mine were siezed up.
