When you steer your Nissan around a corner, many components are in place, working together, to ensure that it turns safely and reliably. The final link between the steering rack and the wheels is the Nissan ball joint. This part works similar to the human shoulder, allowing the tire to turn freely with the power of the steering rack, while still allowing the suspension the freedom it needs to move. The Nissan ball joint consists of a small ball that is surrounded by a socket. Both of the parts are metal, and require a certain amount of lubrication to avoid damage to the surfaces. On many vehicles, the Nissan ball joint is a sealed system. If the part runs out of lubrication, the only thing to do is replace it when it becomes a detriment to the steering system and the safety of the vehicle. Some versions of the Nissan ball joint, however, will have a grease fitting on the part, allowing extra lubrication to be added as needed, which is usually about twice a year. Even with perfect amounts of lubrication, the time will come when the surfaces of the Nissan ball joint are worn enough that it will create vibrations or a loose feeling in the steering.
