A tie rod end (also known as a tie rod) is part of your vehicles steering system - it ties various steering components together to allow your wheels to turn. Tie rod ends are built with a ball-and-socket design, just like your hip, and need to be replaced as they wear out. A worn tie rod end causes poor handling and makes it difficult or impossible to achieve an alignment, which leads to rapid tire wear. Replacing your worn tie rod ends gives a noticeable improvement in steering feel, handling, and safety. BUY WITH CONFIDENCE.
