Product Overview

The wheel hub, OEM number 31206874443, is the front hub with bearing fitted across the BMW i3, i3s, i8, X1, X2, 228i Gran Coupe, and M235i xDrive Gran Coupe, along with related MINI Cooper, Cooper Clubman, and Cooper Countryman models. This part number has since been superseded by 31208845775, though 31206874443 remains widely referenced and stocked. Since this hub spans both BMW's electric i-series and its compact SUV and MINI lineup, it's a genuinely versatile part for anyone stocking BMW and MINI front axle components.

Worn units typically show up as a squeaking or grinding noise from the wheel, vibration felt through the steering wheel, or looseness felt when rocking the wheel by hand. GSK Auto manufactures this hub 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 a Wheel Hub?

Function: The wheel hub with bearing 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: The bearing is integrated into the hub assembly, so sealed bearing races allow smooth rotation under load while resisting both radial and axial forces from cornering, braking, and road impacts, keeping the wheel running true.

Importance: On BMW's i3 and i8, the hub also has to accommodate the unique weight distribution of these electric and hybrid platforms, so using the correct application matters for handling precision.

Common Failures & Signs: Bearing wear causing a squeaking or grinding noise from the wheel. Vibration felt through the steering wheel, particularly at highway speeds. Looseness or play felt when the wheel is rocked by hand. Uneven tire wear linked to bearing play affecting wheel alignment.
