GKN Loebro 306947 CV Axle Assembly

The GKN Loebro 306947 CV axle assembly is built with OE technology for precise driveline performance. It uses GKN Automotive Face Spline hub connection technology to reduce weight while maintaining strong torque transfer at the wheel hub.

  • Front left CV axle assembly for select BMW applications
  • Inner joint diameter: 87 mm
  • Inner joint spline count: 27
  • Outer joint diameter: 86 mm
  • Outer joint spline count: 37
  • Length: 595 mm
  • Thread size: M16x1

OE Technology and Fitment

This axle assembly is engineered for BMW X3 and BMW X4 front left applications that require a 595 mm shaft length. It fits 2011-2017 BMW X3, front left, and 2015-2018 BMW X4, front left. The 306947 part number is also referenced in OE and aftermarket catalogs for the same application.

Face Spline joint design transfers torque through the face of the joint rather than a more complex shaft connection. That approach supports efficient hub connection packaging for rear-wheel drive and 4x4 driveline layouts used by premium vehicle manufacturers.

Common Repair Uses

  • Restores driveline operation after CV joint wear
  • Addresses clicking or popping during turns
  • Helps correct vibration from a worn axle shaft
  • Replaces a damaged front left axle on BMW X3 or BMW X4
  • Supports repair of torn boots, grease loss, or joint play

Installation Notes

Verify axle length, spline counts, and hub connection details before installation. Confirm front left position and match the M16x1 thread specification to the vehicle’s original setup. Inspect related suspension and hub components during service to help prevent repeat driveline noise or premature wear.

Quality Assurance

GKN Loebro is part of GKN Automotive, a global driveline systems manufacturer with OE-level engineering used by premium vehicle makers. This part cross-references TrakMotive BM-8162 for the same application.
