**Includes inner and outer tie rod, a common source of steering issues** Tie rods are an often overlooked maintenance item which can cause steering performance loss and alignment issues. The outer ball joint which connects the tie rod to the wheel spindle can easily wear out from thousands of miles of driving. In addition, the rubber boot can also wear out allowing dirt and water to get inside the joint. The inner joint is also known to develop play with high mileage which can also have an effect on steering performance.
