• Clicking or snapping noise during turns
• Grease leakage from a torn or cracked CV boot
• Vibration during acceleration
• Grinding or rumbling from the rear driveline area
• ABS warning light caused by axle sensor ring or related damage

Installation Notes and Tips

Fits 2004-2010 Toyota Sienna, rear left and rear right. Do not let the CV axle hang unsupported during service, since that can damage the inner joint. Always replace the axle nut rather than reusing a prevailing-torque nut, and torque the new nut to the manufacturer’s specification with a torque wrench. When replacing CV drive axle assemblies, install new transaxle seals 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 OE performance targets. Shafts are checked for straightness to help reduce runout-related vibration, and the boot and grease design are selected to improve durability in demanding driveline service.
