A used Audi power steering rack / gear, OEM part number 8W1423055AE, also supersedes 8W1423055AC, 8W1423055S, 8W1423055Q, 8W1423055N, and 8W1423055L. This rack provides hydraulic assist for steering input on models with EA888 Gen 3 2.0L TFSI, 2.9L twin-turbo V6, and 3.0L supercharged/turbocharged engines. A failing rack often leaks fluid from the pinion seal or shows uneven steering effort, making turning difficult or noisy. This used unit was removed from a donor vehicle and is function-tested for core integrity.
