Installation Notes

Fits 2005-2011 Audi A6 Quattro, front left. Do not let the axle hang unsupported during service, as this can damage the inner joint. Always install a new spindle nut and torque it to the vehicle manufacturer’s specification; do not reuse a prevailing-torque lock nut. If the transaxle seal shows wear or damage, replace it during axle service to help prevent leaks. If the ABS warning light appears after installation, inspect the sensor ring, sensor, and nearby wiring for damage.

Quality Assurance

Cardone verifies CV axle shafts for straightness and uses engineering updates aimed at reducing repeat failure. The axle is built with materials and assembly methods selected to support OE-level driveline performance on the Audi A6 Quattro platform.
