Product Details

This Cardone CV axle assembly is designed for Ford Fusion and Mercury Milan front left service where a worn or damaged axle is causing noise, vibration, or driveline instability. Cardone’s CV axle engineering focuses on the failure points that commonly affect original units, including boot cracking, seal wear, and shaft runout. Each shaft is individually checked for straightness to help deliver smooth, vibration-free operation at speed. This part cross-references Ford OE numbers AE5Z3A427C and AE5Z3A427F for the same application.

Common Problems This Part Can Address

• Clicking or snapping during turns from a worn outer CV joint
• Grease leakage on the chassis or suspension from a ruptured boot
• Front-end vibration caused by axle runout or shaft wear
• ABS warning light concerns related to a damaged sensor ring or axle-mounted ABS component
• Thumping or driveline shake during acceleration from a failing axle assembly

Installation Notes and Tips

Install this CV axle on the front left side only for the listed Ford Fusion and Mercury Milan applications. Always replace the axle nut with the supplied self-lock nut and torque it to manufacturer specifications with a torque wrench. Do not use an impact wrench on the retaining nut. Never let the axle hang unsupported during service, and replace transaxle seals when removing and reinstalling 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 uses engineering and testing methods developed around common CV axle failure modes, including boot durability, seal life, and shaft straightness. The axle shaft is verified for runout to help reduce vibration, and the sealing surfaces are precision-machined after heat treatment to support proper fit and long service life.
