This axle is engineered for front-position service on Audi A4 Quattro and Audi A5 models, including updated-design coverage for the A4 Quattro front left and front right positions. The axle uses a flange-style inboard joint, an Audi-style spline bolt outboard joint, and a 42-spline outboard configuration to match the listed applications. TrakMotive AD-8170 is a direct-fit replacement for vehicles that require the specified compressed length, bolt pattern, and joint style.

This part cross-references Audi OE numbers 8W0407271 and 8W0407271D for the same application.

The axle nut is not included, and the ABS tone ring is not included. Verify whether the vehicle is equipped for an ABS or non-ABS axle configuration before ordering.
