Installation Notes and Tips
When installing the Cardone CV Axle Assembly 66-7378, avoid letting the CV axles hang unsupported to prevent damage to the joints. Use a torque wrench to tighten the stake-type axle nut to the manufacturer’s specifications; do not use an impact wrench for this step. It is recommended to replace any seals or retaining components during installation to ensure a proper fit and prevent leaks. The splined connections on both input and output shafts require careful alignment to avoid damage.
