A-Premium CV Axle Shaft Assembly for Subaru Impreza/Legacy/Outback Front Left or Right — OE Fit, 25/27 Splines

A-Premium Front Driver or Passenger Side CV Axle Shaft Assembly is a direct-fit front axle engineered to restore drivetrain power for compatible Subaru Impreza, Legacy, and Outback models.

When a torn CV boot, worn spline, or damaged joint leaves your Subaru clicking while turning or leaking grease, replacing the complete CV axle is a practical fix. This A-Premium assembly is offered for either front left (driver) or front right (passenger) installation and matches OE-style specifications so it installs with minimal modification. It ships with the axle nut included and is backed by a one-year unlimited-mileage guarantee.

Will this axle fit my Subaru model and year?

The assembly is compatible with a range of Subaru vehicles: Impreza (2008–2015), Legacy (2005–2009), and Outback (2005–2009). Verify the part reference numbers and spline/thread counts against your vehicle before ordering to ensure a precise match.

• Compatible models: Subaru Impreza 2008–2015, Legacy 2005–2009, Outback 2005–2009
• Reference numbers: 28321AG00B, 28321AG00D, 28321AG01B, 28321FG000, 28321FG002, 28321FG003, 28321FJ000, NCV66002, 667355, 66-7355
• Check physical specs: 25 input splines, 27 output splines, M22 x 1.5 spindle nut thread

What are the key specifications I should compare before purchase?

Confirming a few measurements and features eliminates guesswork. This axle’s compressed length, spline counts, and spindle nut thread size are the primary compatibility markers to match against the vehicle’s original component.

• Compressed length: 30.71 inches for correct fit and engagement
• Input shaft spline count: 25; output shaft spline count: 27 to match transmission/differential mating
• Spindle nut thread: M22 x 1.5; axle nut included for convenience
• ABS ring: Not included — confirm your vehicle’s ABS sensor arrangement

How does replacing the entire CV axle help compared to repairing a boot or joint?

Replacing the complete axle eliminates worn internal components and contaminated grease that a boot-only repair can miss. A full-assembly swap restores correct spline engagement and joint geometry, reducing the risk of premature failure when performed with proper installation.

• Removes worn internal joints and contaminated grease for longer service life
• Assures correct spline and length match for smooth power transfer
• Includes axle nut to simplify reassembly

What warranty and reliability assurances come with this A-Premium axle?

A-Premium supports this axle with a one-year unlimited-mileage guarantee, covering manufacturing-related defects within that period. This provides a straightforward recourse if the part fails due to workmanship under normal use.

• One-year unlimited-mileage guarantee from A-Premium
• Manufactured to meet OE-style form, fit, and function
• Sold as a complete front axle assembly for driver or passenger side

Who is this for? If you own a Subaru Impreza (2008–2015), Legacy (2005–2009), or Outback (2005–2009) and are experiencing clicking noises when turning, torn CV boots, grease leakage, or vibration during acceleration, this A-Premium front CV axle assembly is intended as a direct replacement option. It’s suitable for DIY mechanics comfortable with front-end disassembly or professional installers who want an OE-style replacement with a convenient warranty and included axle nut.
