<strong>Tie Rod:</strong> The tie rod connects the knuckles and transfers the steering input from the draglink to the wheels by way of the knuckles. The addition of bigger rolling stock can stress factory tie rods. Worn tie rod ends, which can present symptoms such as a shaking steering wheel, chassis vibrations, and wandering, should be replaced immediately. A good tie rod end should exhibit rotational movement at the joint end, but will not have any up and down or side-to-side play. Heavy-duty tie rods that are more resistant to loads from bigger tires are readily available in the aftermarket.
