Product Details

Cardone’s CV Axle Assembly line is engineered from testing and remanufacturing experience focused on the causes of repeat CV failure. For this application, part number 66-2165 is built to deliver smooth driveline operation on the front right side of the Ford Five Hundred, Ford Freestyle, and Mercury Montego. The design emphasizes boot durability, accurate shaft geometry, and reliable sealing to help maintain consistent performance in daily driving.

This part cross-references Ford 5F9Z3B436BA and Mercury 6F9Z3B436B for the same application.

Common Repair Symptoms

• Clicking or snapping noise during hard turns
• Grease on the chassis or suspension from a torn CV boot
• Front-end vibration during acceleration
• Wobble or shudder while turning
• ABS warning light after axle replacement if the sensor ring is damaged

Installation Notes

• Do not let the axle hang unsupported during service.
• Use a torque wrench on the retaining nut and follow manufacturer torque specifications.
• Do not reuse a prevailing-torque lock nut; install the new nut supplied with the axle.
• Replace transaxle seals when installing CV axle assemblies to help prevent leaks.
• Inspect the ABS sensor, wiring, and sensor ring before final assembly.

Quality Assurance

Cardone engineers CV drive axles to meet or exceed original equipment performance targets by addressing common failure causes such as boot cracking, seal wear, and shaft runout. Each shaft is checked for straightness to support vibration-free operation at speed.
