Detailed Description

GKN Loebro 305721 is a CV axle assembly designed for the front left position on the Volvo XC90. It uses a high-precision Ballspline plunge unit, which allows the axle to move axially while transmitting torque, helping maintain smooth driveline operation under suspension travel. The OE-style construction and exact spline and tone ring specifications make this axle a direct-match replacement for the listed XC90 fitments.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. If you are replacing a worn Volvo XC90 front left axle, 305721 is the part number to verify against your original unit before installation.

What This Part Helps Address

• Clicking or popping noises during turns from a worn CV joint
• Vibration or shudder from a damaged axle shaft
• Grease leakage from a failing axle boot or joint assembly
• ABS warning concerns related to incorrect tone ring specification
• Driveline play caused by excessive joint wear

Installation Notes and Tips

Fits 2006 Volvo XC90, Front Left, AW55-50/51SN. Fits 2003-2005 Volvo XC90, Front Left. Fits 2004 Volvo XC90, Front Left, AW50/51 AWD. Confirm the inboard and outboard spline counts, compressed length, and axle nut thread size before installation to ensure the replacement matches the original axle.

Because this assembly includes an ABS tone ring, verify sensor and ring alignment during installation. Always inspect related suspension and hub components for wear that could affect axle life.
