The tie rods control the side-to-side direction of the tires. Typically the toe setting (whether the tires are pigeon-toed or duck-footed) of an automobile is critical to =/- .13" or less. The tie rods control this setting and when they become loose from wear the tires can steer themselves (slightly) in any direction. The driver notices this as 'free-play' or 'lag' in the steering. Loose tie rods will also cause edge wear on both tires as a result of the toe setting being incorrect. The rack boots cover the inner tie rod ends and keep debris out of the rack and pinion steering gear.
