About the Cardone CV Axle Assembly Product Line

The Cardone CV Axle Assembly line focuses on delivering quality replacement CV axles that meet or exceed OEM specifications. Each assembly is designed to provide reliable driveline function and durability, making it a suitable choice for Subaru Impreza owners seeking a direct-fit replacement part. This product line emphasizes precision manufacturing and thorough inspection to reduce vibrations and ensure proper fitment.

Product Details and Specifications

This CV axle assembly features a compressed length of 30.63 inches, matching the exact dimensions required for proper installation on Subaru Impreza vehicles. The input shaft is splined with 25 splines, while the output shaft has 27 splines, ensuring compatibility with the vehicle’s drivetrain components. The axle nut locking type is stake, which provides a secure and reliable fastening method. Note that this assembly does not include an ABS ring, so it is intended for vehicles without ABS sensor requirements or where the ABS ring is retained from the original axle.

Common Applications and Problem Solving

  • Replaces worn or damaged CV axles causing vibrations or clicking noises
  • Addresses issues with axle shaft runout that can lead to driveline imbalance
  • Restores proper power transfer to front wheels in Subaru Impreza models
  • Eliminates wheel wobble or grinding noises during turns or acceleration
  • Solves problems related to broken or worn outer CV joints

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.

Quality Assurance and Warranty

Each Cardone CV Axle Assembly undergoes 100% inspection for runout to minimize vibrations and ensure smooth operation. The shafts are balanced at the factory to maintain driveline stability. While specific warranty details are not provided here, Cardone products typically come with a limited warranty covering defects in materials and workmanship. Always consult the product documentation or manufacturer for exact warranty terms.
