Steering-rod ends and joints are wear items. When you add larger tires, wheeling, and high mileage to the mix, you are bound to have one or two worn parts. However, the most common front end joint failure isn’t in the steering system, but more likely the track bar. In a stock TJ application, the culprit is often the joint on the frame end of the bar. You can pick up a replacement track bar assembly from your local parts store for around $60.
