Used OEM Audi power steering rack/gear, part number 8W1423055BC, superseding 8W1423055BA. This steering rack controls vehicle direction by converting rotational steering wheel input into linear movement of the tie rods. A common failure symptom is fluid leakage from the rack seals or a loose, wandering steering feel.
