Product Details

Cardone 66-7370 is a new CV axle assembly for Subaru rear driveline service, covering Outback, Legacy, and Baja fitments across the 2001-2006 model years. It is built around Cardone’s CV axle engineering process, which emphasizes straightness verification for vibration control and improved resistance to repeat failure. For Subaru Outback and Subaru Legacy rear axle replacement, this part is a direct-fit solution for restoring quiet operation and consistent power delivery.

This part cross-references Subaru 28421AE00A and 28421AE09A for the same application.

Common Problems This Axle Can Address

• Clicking or snapping noises during turns
• Grease leakage from a torn or cracked CV boot
• Vibration during acceleration or at speed
• ABS warning light caused by a damaged sensor ring or related axle hardware
• Grinding or binding from a worn outer or inner CV joint

Installation Notes

• Do not let the CV axle hang unsupported during service; support the shaft to avoid joint damage.
• Use a torque wrench and tighten the axle nut to the vehicle manufacturer’s specification.
• Do not reuse a prevailing-torque lock nut; replace it with the supplied spindle nut.
• Install new transaxle seals when replacing CV drive axle assemblies to help prevent leaks.
• If the ABS light remains on after installation, inspect the sensor ring, sensor, and nearby wiring for damage.

Quality Assurance

Cardone engineers and tests its CV drive axles to meet or exceed original equipment performance targets. Shafts are individually checked for straightness to help reduce vibration, and the boot and grease design are selected to improve durability in demanding driveline service.
