Cardone 66-2241 CV Axle Assembly - Rear Left

Rear Left CV Axle for Escape and Mariner

Cardone 66-2241 is a new CV axle assembly built for rear left applications on the 2008-2012 Ford Escape and 2008-2011 Mercury Mariner. It is engineered for OE-level fit and smooth driveline operation, with attention to boot durability, shaft straightness, and seal performance.

Key Features

• Fits 2008-2012 Ford Escape, rear left
• Fits 2008-2011 Mercury Mariner, rear left
• ABS ring included with 44 teeth for proper wheel speed signal transfer
• Self-lock axle nut style with spindle nut included
• Compressed length: 30.437 in.
• Splined connections: 25-tooth input shaft and 26-tooth output shaft
• Neoprene boot design with added bellows where needed to reduce stress and ozone cracking
• High-temperature, high-torque grease for driveline durability
• Boot clamps are pneumatically crimped for a secure seal
• Transmission seal diameter is precision-machined after heat treatment for consistent sealing

Product Details

Cardone CV axle assemblies are engineered from testing and remanufacturing experience to address common failure points found in original driveline components. For this application, part number 66-2241 is built to deliver vibration-free operation through individually verified shaft straightness and 100% runout inspection. The design also focuses on boot life and seal integrity, which matters on rear left Ford Escape and Mercury Mariner driveline service where contamination and joint wear can quickly affect performance. This part cross-references Ford 8L8Z4K139A and Mercury 8L8Z4K139A for the same application.

Common Problems This Part Can Address

• Clicking, snapping, or grinding noises from the rear driveline
• Grease leakage from a torn or cracked CV boot
• Vibration during acceleration or at speed
• ABS warning light caused by a damaged axle sensor ring or related signal issue
• Binding, wobble, or driveline shudder from a worn axle assembly

Installation Notes and Tips

• Fits 2008-2012 Ford Escape, rear left, and 2008-2011 Mercury Mariner, rear 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 follow manufacturer torque specifications.
• Do not reuse a prevailing-torque lock nut; replace it with the supplied spindle nut.
• Inspect seals and related ABS wiring or sensor components before final assembly.

Quality Assurance

Cardone engineers CV drive axles to meet or exceed OE performance targets through application-specific testing, shaft straightness verification, and inspection for runout. The brand’s process is focused on reducing repeat failure causes such as boot cracking, seal leakage, and vibration.
