TRQ Front Right CV Axle Shaft Assembly AWD Passenger Side - Direct Fit

Our review of the TRQ Front Right CV Axle Shaft Assembly finds it best suited for owners of 2004-2010 Toyota Sienna with all wheel drive who need a straightforward, vehicle-specific replacement. The biggest reason to buy is the assembly's direct fit design and OE reference compatibility, which simplifies installation and reduces downtime compared with rebuilding a worn half-shaft. Installed as an OE replacement with neoprene boots and moly grease, this axle aims to restore driveline function with minimal fuss.

Key Features

• Direct Fit: Designed to match the factory geometry so the axle installs without modifications on compatible 2004-2010 Toyota Sienna AWD passenger side applications.
• OE Replacement: Uses OE reference numbers 4341008041 and aftermarket reference 665251 to ensure part compatibility and easier parts lookup.
• Durable Boots: Neoprene inboard and outboard boots provide improved resistance to tears and environmental exposure compared with some stock materials.
• Pre-greased Joints: Moly-greased joints and included axle nut reduce initial break-in wear and make the assembly ready for installation out of the box.
• Complete Unit: Assembly includes axle nut and ABS tone ring when applicable, so there are fewer missing components to source during repair.

Who It's For

This axle assembly is aimed at do-it-yourself mechanics and independent shops repairing AWD Toyota Sienna models from 2004 through 2010 who want a part that fits without custom work. The direct fit design and included hardware help speed up a front passenger-side replacement and reduce time under the vehicle.

It is not intended for vehicles outside the listed years or non-AWD models, and drivers seeking a performance or heavy-duty aftermarket upgrade should look elsewhere. Buyers who require lifetime warranty coverage or OEM-branded assurance may prefer an authorized dealer part instead.
