When you turn the wheel of you Mercedes, it may be a more complex process than you think. Because the left and right side wheels must travel in different-sized circular paths, it is necessary for the Mercedes ball joint/tie rod assembly to be finely tuned to allow the tires free motion. The threaded rod on the tie rod is one of the devices that make this possible, allowing the tie rod to be lengthened or shortened to achieve the correct geometry. When the Mercedes Benz ball joint/tie rod is not in correct adjustment, one or more of the tires may grind on the pavement instead of rolling free, which will result in an area of accelerated tire wear. This can be repaired in most cases by getting the front-end aligned, but when the Mercedes Benz ball joint/tie rod assembly has been on a car for many years, it may be too worn to achieve a proper alignment. In this case, replacement will be necessary, and you can find the correct Mercedes Benz ball joint/tie rod parts for your car in our vast online catalog, in stock and ready to ship, in most cases.
