Product Overview

The axle shaft assembly, OEM number 1643300801, is the front left CV axle fitted to the Mercedes-Benz ML-Class (ML320, ML350, ML450, ML500, ML550) and GL-Class (GL320, GL350, GL450, GL550), all built on the W164/X164 platform. Since this axle spans both the ML and GL model lines across multiple engine variants, it's a high-turnover part number worth stocking in volume for distributors serving Mercedes-Benz SUV driveline parts demand.

Worn or failing axle assemblies 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 assembly 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 Assembly?

Function: The axle shaft assembly 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 a 4MATIC AWD SUV platform, a properly functioning axle assembly 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.
