Product Overview

The axle shaft, OEM number 31607622913, is the front left (driver side) CV axle fitted to the BMW X5 and X6 (F15/F16 generation), covering the 2014-2019 model years across the 3.0L turbocharged inline-6 and xDrive35i variants. Since this axle is specific to the newer F15/F16 generation, it's a growing-demand part number as these vehicles age into their replacement window, worth stocking alongside the earlier E70/E71 axle numbers.

Worn or failing axle shafts typically show up as clicking or popping noise when turning, vibration at speed, or visible grease around the CV boot from a tear. GSK Auto manufactures this axle shaft to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

What Is an Axle Shaft?

Function: The axle shaft transfers power from the differential to the wheel hub, allowing the wheel to rotate while accommodating suspension and steering movement through its CV joints.

Working Principle: Inner and outer constant velocity (CV) joints connect the axle shaft between the differential and wheel hub, allowing the shaft to transmit rotational power at a constant speed even as the angle changes with suspension travel and steering input. Rubber boots seal each joint, retaining grease and keeping out contaminants.

Importance: On an AWD SUV platform, a properly functioning axle shaft is essential for smooth power delivery and reliable handling, especially during cornering.

Common Failures & Signs: Torn CV boot allowing grease to leak out and dirt to enter. Clicking or popping noise when turning, especially at low speed. Vibration that increases with vehicle speed. Grease visible around the CV joint or flung inside the wheel well.
