If your Mercury is out of alignment, it can cause not only uneven tire wear, it can also cause other components of the suspension and steering systems to experience higher friction and vibration, hastening their demise. When a car is aligned, the mechanic makes slight adjustments to items such as the Mercury ball joint/tie rod assembly, ensuring that the tires travel in a straight line during normal driving, and that they turn properly while steering. All of the tires are also checked for the correct vertical angles. The older your Mercury is, the harder it becomes to adjust parts like the Mercury ball joint/tie rod system. It is a natural problem, because these items are always prone to torsion forces, friction, and heavy loads.
