Product Overview

The wheel hub, OEM number 31206876840, is the front hub with bearing fitted across the BMW 2 Series (F22, F23, F87), 3 Series (F30, F31), and 4 Series (F32, F33, F36), rear-wheel-drive variants, model years 2012-2021. This is one of the most widely referenced BMW front hub part numbers, spanning three model series across nearly a decade of production, including models from the 228i and 320i through the M240i and 440i.

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.

(Confirm against your VIN or chassis code before ordering - this hub is specific to RWD variants, and this part number spans multiple body styles and trims across nearly a decade of production, so it's worth double-checking drivetrain and exact chassis before ordering at volume.)

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: Because the bearing is integrated into the hub on this design, the two components can't be serviced separately, so when the bearing wears, the entire hub assembly needs to be replaced.

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.
