Front Driver & Passenger CV Axles for 2006-2009 Ford Fusion 2.3L

In this review the focus is on the TRQ front driver and passenger CV axle assembly set as a direct-fit replacement for several mid-2000s sedans. The bottom line: this 2-piece kit is best for DIY mechanics and independent shops who need a full front axle replacement that matches OE reference numbers and installs without modification. The reviewer found the set restores driveline function and removes common vibration and noise symptoms when fitted to compatible 2006-2009 Ford Fusion, 2006-2009 Mercury Milan and 2003-2008 Mazda 6 models.

Key Features

• Direct Fit: Designed to be an OE replacement so the assemblies install without modifications on listed vehicles.
• Complete 2-Piece Kit: Includes both front driver and passenger side CV axle assemblies, allowing both sides to be serviced together for balanced performance.
• Neoprene Boots: Uses improved neoprene boot material for better resistance to tearing compared with older stock boots.
• Moly Greased: Packed with moly grease and a specially designed grease shield to reduce premature wear and maintain smooth operation.
• Vehicle Specific Fitment: Manufactured to match OE reference numbers so buyers can check fitment lists for exact compatibility before purchase.
• 100% New Components: Built from new raw materials to restore original driveline feel and reduce play in the joint.

Who It's For

This axle set is ideal for owners of 2006-2009 Ford Fusion and Mercury Milan vehicles with the 2.3L 4-cylinder, and for 2003-2008 Mazda 6 i owners looking for a full front axle replacement that references OE numbers like 6E5Z3A427A and GD422550XA. It suits DIYers with basic mechanical skills and shops that want a ready-to-install pair rather than assembling individual components.

Those who need heavy-duty or long-term commercial use axles, or who require stainless or specialty high-mileage boots, should consider higher-end or rebuilt options; several users have reported outer boot failure after extended use, so long-term durability is an important consideration.

Pros & Cons

Pros

• Good fit and compatibility with listed vehicles, reducing installation time.
• Improved neoprene boots and moly grease help reduce noise and vibration after replacement.
• Includes both sides in one kit, offering better value than buying axles individually.
