Front Driver & Passenger CV Axle Set for 2004-2006 Subaru WRX/Baja - 2

In this review the reviewer looks at the 2 piece CV axle assembly set designed for 2004-2006 Subaru WRX Wagon and 2004-06 Baja Turbo with automatic transmission. The bottom line: this kit is for a DIYer or independent mechanic who wants a direct fit replacement that mirrors OE geometry and simplifies installation. The biggest reason to buy is the pre-assembled, application-specific design and neoprene boots that promise a tighter manufacturing tolerance than typical aftermarket shafts, which helps restore driveline smoothness and reduce vibration after replacement.

Key Features

• Complete 2-piece kit: Includes one front driver side and one front passenger side CV axle assembly so both sides can be replaced at the same time for balanced performance.
• Direct fit design: Application specific assemblies are built to fit the 2004-2006 Subaru WRX Wagon and 2004-06 Baja Turbo automatic models with no modification required.
• Neoprene boots: Boots are more durable than stock material, helping to protect joints from contamination and extend service life.
• Moly greased joints: Pre-greased inner and outer joints reduce premature wear and help maintain smooth operation under load.
• Tighter manufacturing tolerances: Produced to meet or exceed OE specifications for improved durability and a closer match to original geometry.
• Reference numbers included: Multiple reference numbers are provided to help confirm compatibility with existing parts and service documentation.

Who It's For

This set is aimed at owners of 2004-05 Subaru Impreza WRX Wagon, 2006 Subaru Impreza WRX Wagon, and 2004-06 Subaru Baja Turbo equipped with automatic transmissions who need a full front axle replacement. It suits DIY mechanics who prefer to replace both axles at once to eliminate uneven wear and restore driveline balance.

It is less appropriate for drivers seeking a lifetime high-performance or track-focused upgrade; some customers have reported outer boot failures after extended use, so those needing extreme durability under aggressive conditions may want a heavy-duty or OEM-specified alternative.

Pros & Cons

Pros

• Direct fit 2-piece kit makes replacement straightforward and time-saving.
• Improved neoprene boots and moly grease help reduce vibration and improve initial durability.
• Manufactured to tighter tolerances for a closer match to OE performance and fit.
• Good value when replacing both sides together versus purchasing parts separately.

Cons

• Some users reported outer boot durability issues after about a year, so longevity may vary by driving conditions.
• Not marketed as a heavy-duty or racing component, so those needs may require a different part.

Specifications

Our Verdict
