Product Details

This Cardone CV axle assembly is built around the brand’s CV driveline engineering process, which focuses on common failure points such as boot cracking, seal wear, and shaft runout. The result is a replacement axle designed for direct service on Mazda CX-9 rear left applications, including 2010 and 2011-2015 models. Part number 66-8224 is supplied as a complete axle with an instruction sheet and is built with a stake-style axle nut locking type and M22 x 1.5 spindle nut thread size.

This part cross-references Mazda GD702560XA for the same application.

Common Problems This Part Can Address

• Clicking, snapping, or grinding noises from the rear driveline during acceleration or turning
• Grease leakage around the axle boot or underbody contamination from a ruptured boot
• Vibration caused by axle shaft runout or a worn CV joint
• ABS warning light issues related to a damaged sensor ring or wheel speed signal disturbance
• Binding, thumping, or driveline shudder from a worn or failing rear axle assembly

Installation Notes

Fits 2011-2015 Mazda CX-9, rear left, and 2010 Mazda CX-9, rear left. Do not let the axle hang unsupported during service, as this can damage the inner joint. Use a torque wrench on the retaining nut and follow manufacturer torque specifications; do not use an impact wrench for final tightening. Replace the axle nut rather than reusing a prevailing-torque lock nut, and install new transaxle seals when replacing CV drive axle assemblies to help prevent leaks. If the ABS light remains on after installation, inspect the sensor ring, sensor, and nearby wiring for damage.

Quality Assurance

Cardone applies CV axle testing and engineering methods aimed at matching or exceeding original equipment performance. Shafts are checked for straightness, and the axle design addresses known failure causes to support reliable operation in Mazda CX-9 service.
