Protective bellows boots around the steering rack and inner tie rods shield the rack from dirt and moisture. These flexible rubber sleeves cover the ends of the rack and the inner tie rods, sealing out dust, water, and road grime while keeping the lubricant inside. They’re designed to move with steering and suspension, thanks to their corrugated structure. When they’re intact, they prevent wear, corrosion, and binding of the rack gear and joints. If a boot cracks or tears, contaminants can enter, accelerating wear and causing sloppy steering or noise. Other options don’t serve this purpose: dust caps protect wheel hubs, weather strips seal door gaps, and seals in other systems aren’t the protective boots for the rack.
