Audi power steering rack / gear, OEM part 4G1423055BG, is a used genuine factory component. This steering rack also replaces a long series of earlier numbers including 4G1423055AB, 4G1423055AN, and many others in the 4G1 prefix. It's fitted to Audi A6, A7, A8, S6, S7, S8, and RS7 models with engines ranging from the 2.0L turbo four to the 4.0L V8 and 6.3L W12. When this rack begins to fail, common symptoms include fluid leaks from the seals or heavy, inconsistent steering effort.
