Product Overview

The CV axle shaft, OEM number A1664102901, is the front drive shaft fitted to the Mercedes-Benz GLE, W166 chassis, covering the GLE400, GLE450 AMG, and GLE43 AMG, and the GLS450, all 3.0L V6 applications, model years 2016-2019. Since this shaft covers multiple GLE and GLS trims, it's a steady part to stock for anyone servicing these Mercedes SUV platforms.

Worn or damaged units typically show up as a clicking or popping noise when turning, especially under acceleration, visible grease flung around the wheel well from a torn boot, or vibration that increases with vehicle speed. GSK Auto manufactures this CV axle 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.

(Confirm against your VIN or chassis code before ordering - this shaft covers multiple GLE and GLS trims with the 3.0L V6, so it's worth double-checking the exact model and side before ordering at volume.)

What Is a CV Axle Shaft?

Function: The CV axle shaft, also called a driveshaft, transfers rotational power from the transmission and differential to the wheel hub, while allowing for the up-and-down motion of the suspension and, on the outer joint, the turning angle of the steering.

Working Principle: Constant velocity joints at each end of the shaft allow it to flex at an angle while still transmitting rotational force smoothly and at a constant speed, even as the suspension moves and the wheels turn.

Importance: On a heavy AWD SUV platform like the GLE and GLS, the front axles handle both drive torque and steering angle simultaneously under significant vehicle weight, so they experience real mechanical stress and are a routine wear item over the vehicle's service life.

Common Failures & Signs: Torn or cracked boot allowing grease to escape and dirt to enter, accelerating internal wear. Clicking or popping noise when turning, particularly under acceleration. Grease visible flung around the inside of the wheel well. Vibration that increases with vehicle speed, indicating worn internal components.
