Product Details

The Cardone CV Axle Assembly 66-2261 is built for rear left Ford Explorer applications from 2011-2019. Cardone uses testing and engineering experience to address common CV axle failure points, including boot cracking, seal wear, and shaft runout. This approach supports consistent driveline performance in daily driving conditions and helps maintain smooth power transfer at speed. This part cross-references Ford BB5Z4K139A and BB5Z4K139B for the same application.

Common Problems This Part Can Address

• Clicking or snapping noises during turns
• Grease leakage around the axle boot or underbody
• Vibration during acceleration or at road speed
• Wobble or driveline shake while cornering
• Noise caused by a worn or damaged rear CV joint

Installation Notes

• Do not let the CV axle hang unsupported during service.
• Use a torque wrench on the retaining nut and tighten to manufacturer specifications.
• Do not reuse a prevailing-torque lock nut; install the supplied new nut.
• Inspect related seals and replace worn transaxle seals when required.
• If ABS concerns appear after installation, inspect the sensor ring, sensor, and wiring for damage.

Quality Assurance

Cardone designs and verifies CV drive axles to meet or exceed original equipment performance targets. Each shaft is checked for straightness to help deliver vibration-free operation, and the boot and grease materials are selected to support long service life in demanding driveline use.
