Product Details

Cardone designs its CV Drive Axles around common failure points found in original units, including boot cracking, seal wear, and vibration from shaft runout. Each shaft is individually checked for straightness to help deliver vibration-free performance at speed. For Audi A6 Quattro rear axle service, 66-7461 provides a direct replacement solution that supports ABS function and driveline smoothness.

This part cross-references Audi 4B0501203C and 4B0501203CX for the same application. The Cardone CV Axle Assembly line focuses on OE-style driveline replacement parts engineered for consistent fit, sealing, and joint performance.

Common Problems This Part Addresses

• Clicking or snapping during hard turns
• Grease on the chassis or suspension from a torn CV boot
• Vibration or thump under acceleration
• ABS warning light after axle replacement due to sensor ring or wiring damage
• Grinding noise from the front or rear driveline area caused by joint wear

Installation Notes

• Do not let the CV axle hang unsupported during service; this can damage the inner joint
• Use a torque wrench on the retaining nut and tighten to the vehicle manufacturer’s specification
• Do not reuse a prevailing-torque lock nut; install the new nut supplied with the unit
• Replace transaxle seals when servicing CV drive axles to help prevent leaks
• Inspect the ABS sensor, ring, and wiring during installation to avoid false warning lights
