There's 2 parts down there one is the outer tie rod end (Autozone #ES3691) and there's another one that Autozone also refers to as a tie rod end. (Autozone #ES3690) The second one has to be out because the other side doesn't make the pop when I shake it, plus something had to put serious strain on the piece I already replaced to make it already fail. I only take it to NTB because we buy our tires through them to get the road hazard warranty on them plus their 3-year alignment package.
