This rubber steering rod boot seals the steering linkage at the front axle, preventing dirt, moisture, and debris from entering the steering joint. It sits over the exposed rod end where the tie rod connects to the steering knuckle. A torn or missing boot allows contamination to reach the ball joint, leading to accelerated wear and steering play. This component is manufactured to the original geometry so that it seats correctly in the groove on the steering arm and clamps securely to the rod. When replacing, ensure the boot is fully seated and the retaining clips are tightened evenly to maintain the seal.
