Keep road grime, water, and debris out of your steering rack with the Beck/Arnley Rack and Pinion Bellows Kit (P/N 103-3166), a direct-fit LEFT-side steering rack boot kit for a wide range of Audi models. The bellows seals the rack's inner tie rod and joint, holding lubricating grease in and contaminants out; a cracked or torn boot lets moisture and dirt reach the rack, which can accelerate wear. If a failed boot is why your steering is leaking grease or collecting dirt, this kit replaces it.
