Product Details

GKN Loebro 305948 is a front right CV axle shaft engineered for BMW driveline service where OE geometry and spline count matter. The Face Spline outboard joint transfers torque through the joint face, reducing connection complexity while maintaining the performance characteristics expected in premium rear-biased and all-wheel-drive platforms. This axle is a direct-fit replacement for select BMW 640i xDrive Gran Coupe, 640i xDrive, 528i xDrive, 535d xDrive, and 535i xDrive models.

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