Product Details

Cardone’s CV Axle Assembly line is engineered from testing and remanufacturing experience focused on common CV failure points. For this application, the axle is built to address boot cracking, seal wear, and shaft runout concerns that can lead to noise, vibration, and grease loss. The Cardone 66-7073 is a direct driveline replacement for Audi front left service where ABS ring compatibility and precise axle geometry matter.

This part cross-references Audi 4D0407271H and 4D0407271S for the same application.

Common Problems This Axle Can Address

• Clicking or snapping during hard turns
• Grease on the chassis or suspension from a torn CV boot
• Front-end vibration caused by axle runout or shaft imbalance
• ABS warning light after axle replacement when the sensor ring is not correct
• Grinding or binding from a worn outer or inner CV joint

Installation Notes

Fits 2000-2004 Audi A6 Quattro, front left; 1997-2001 Audi A8 Quattro, front left; 2001 Audi S8, front left; and 1997-1999 Audi A8, front left. Do not let the axle hang unsupported during service, as this can damage the inner joint. Use a torque wrench on the spindle nut and follow manufacturer torque specifications; do not use an impact wrench for final installation. Replace the prevailing-torque axle nut rather than reusing the old one. When replacing CV drive axles, install new transaxle seals to help prevent leaks.

Quality Assurance

Cardone engineers this CV axle assembly to meet or exceed OE performance targets through application-specific testing, straightness verification, and boot design improvements aimed at reducing repeat failure. The product is new and includes the complete axle and instruction sheet.
