Product Overview

The wheel hub bearing assembly, OEM number 3QF498621, is the front axle hub fitted to the Volkswagen Atlas, model years 2018-2021, all-wheel-drive variants, and the closely related Atlas Cross Sport. Since the Atlas is one of VW's higher-volume SUV models in North American and other export markets, this is a steady part to keep in stock for anyone servicing VW's larger SUV platform.

Worn units typically show up as a humming or grinding noise from the front wheel that changes with vehicle speed, vibration felt through the steering wheel, or an ABS or traction control warning light. GSK Auto manufactures this hub 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.

(Confirm against your VIN or chassis code before ordering - this part is specific to AWD variants, and related mount and axle bolts are not reusable during installation, so it's worth flagging that to your customer before the job.)

What Is a Wheel Hub Bearing Assembly?

Function: The wheel hub bearing assembly supports the wheel, allows it to rotate freely with minimal friction, and carries the vehicle's weight at that corner while also serving as the mounting point for the brake disc and wheel.

Working Principle: Sealed bearings inside the hub allow smooth rotation under load while resisting both radial and axial forces from cornering, braking, and road impacts, keeping the wheel running true.

Importance: The hub bearing also houses the ABS wheel speed sensor tone ring on most applications, so a failing unit can trigger warning lights related to the ABS or traction control system in addition to affecting ride comfort.

Common Failures & Signs: Humming, growling, or grinding noise from the wheel that changes with speed. Vibration felt through the steering wheel, particularly at highway speeds. ABS or traction control warning light triggered by a wheel speed sensor issue tied to the hub. Looseness or play felt when the wheel is rocked by hand.
