Product Details

Cardone builds its CV Drive Axle assemblies around failure prevention, using engineering and testing experience to address common causes of repeat axle problems. The shafts are individually verified for straightness to help reduce vibration, while the boot and seal design focus on keeping grease in and contaminants out. Part number 66-2279 is a direct-fit replacement for drivers seeking a front left CV axle assembly for the Ford Fusion, Lincoln MKZ, or Mercury Milan listed in the fitment data.

This part cross-references Ford/Lincoln/Mercury OE number AE5Z3A427D for the same application.

Common Problems This Part Can Address

• Clicking or snapping noises during turns from a worn outer CV joint
• Grease on the chassis or suspension from a ruptured outer boot
• Vibration under acceleration caused by axle runout or shaft imbalance
• ABS warning light issues after axle replacement when the sensor ring is damaged or incorrect
• Binding or thumping from a worn inner joint or drivetrain misalignment

Installation Notes

• Fits 2010-2012 Ford Fusion, front left
• Fits 2011-2012 Lincoln MKZ, front left
• Fits 2010-2011 Mercury Milan, front left
• Do not let the 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 the prevailing-torque lock nut; install the supplied new spindle nut
• Replace transaxle seals when servicing CV axle assemblies to help prevent leaks
• If the ABS light remains on after installation, inspect the sensor ring, sensor, and wiring near the axle

Quality Assurance

Cardone’s CV axle engineering process includes straightness verification for vibration control, precision-machined seal surfaces, and boot designs intended to resist common failure points. The brand’s remanufacturing and new-part development approach is centered on matching or exceeding OE performance expectations for driveline service.
