OE-Style Front Right CV Axle for BMW xDrive

GKN Loebro 305949 is a front right CV axle assembly built with OE technology for BMW xDrive applications. It combines a plunging inboard joint with Face Spline outboard connection technology to support efficient torque transfer at the wheel hub.

Compatible with select BMW 550i xDrive and 650i xDrive models, this axle is engineered for direct-fit driveline service where precise spline engagement and stable joint operation matter.

Detailed Description

GKN Loebro 305949 uses Face Spline hub connection technology, which transfers torque through the face of the joint rather than a more complex shaft connection. That design supports lower weight and efficient power delivery in demanding rear-wheel-drive and 4x4 driveline layouts. For BMW 650i xDrive Gran Coupe, BMW 650i xDrive, and BMW 550i xDrive front right service, this axle is built to match the listed spline counts, joint types, and overall compressed length.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

  • Clicking or popping from a worn outer CV joint
  • Vibration during acceleration from a damaged axle shaft
  • Grease leakage from a failing CV boot or joint seal
  • Torque transfer issues at the front right wheel hub
  • Driveline noise caused by spline or joint wear

Installation Notes and Tips

Verify front right position, spline counts, and axle length before installation. Confirm M16x1.5 axle nut thread size and check that the vehicle application matches the listed BMW xDrive fitment. Inspect hub, seals, and surrounding suspension components during service to help prevent repeat driveline noise.

Quality Assurance

GKN Automotive is a global driveline systems supplier, and this axle reflects OE-level engineering used in premium vehicle applications. GKN Loebro 305949 is built around the brand’s Face Spline technology for precise hub connection performance.
