Built for OE-Style Performance

Cardone engineers its CV drive axles around common failure points found in original units. Neoprene boots use additional bellows where needed to reduce stress and ozone cracking, while the shaft is individually verified for straightness to help maintain vibration-free operation at speed. High-temperature grease and pneumatically crimped boot clamps support consistent sealing and joint protection. This Cardone 66-3406 CV axle assembly is a direct-fit driveline replacement for front left service on the Hyundai Sonata, Kia Optima, and Kia Magentis applications listed above.

This part cross-references Hyundai 4950738E00 and Kia 495003C401 for the same application.

Common Problems This Part Can Address

• Clicking or snapping noise during turns
• Grease leakage around the axle boot or suspension area
• Front-end vibration during acceleration
• Grinding noise from a worn outer CV joint
• ABS warning light caused by a damaged sensor ring or axle-related signal issue

Installation Notes and Tips

• 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 axle.
• Replace transaxle seals when servicing CV drive axle assemblies to help prevent leaks.
• Inspect the ABS sensor, wiring, and ring during installation to avoid an erratic speed signal.

Quality Assurance

Cardone applies extensive CV axle testing and engineering to meet or exceed OE performance targets. Each shaft is checked for straightness to help reduce vibration, and the boot and seal design is focused on durability in demanding driveline conditions.
