Detailed Description

Cardone part number 66-7418 is a CV axle assembly built for front axle service on select Audi models, including the Audi A4, Audi A5, Audi S4, and Audi S5. Cardone applies testing and engineering experience to address common CV axle failure points, including boot cracking, seal leakage, and vibration from shaft runout. The result is a replacement axle designed for consistent driveline performance and proper fitment on the listed front left and front right positions.

This CV axle assembly uses a 42-spline output shaft, a bolt-style axle nut locking design, and a 19mm spindle nut hex head size with M16 x 1.5 thread. The compressed length is 18.307 inches. ABS ring is not included. This part cross-references Audi 8K0407271Q and 8K0407451DX for the same application.
