28473-FG000 / 512401 Automotive Wheel Hub Unit Bearing

AWD Spline Precision: The internal splined bore is precision-broached to ensure a flawless, play-free connection with the rear drive axle.
Heavy-Duty Wheel Studs: Forged from high-tensile steel to prevent shearing under heavy acceleration or hard braking.
Integrated ABS Capability: Features a sealed, high-durability magnetic encoder to ensure uninterrupted communication with vehicle safety systems.

Deep Application & Technical Narrative:

The 28473-FG000 (industry standard 512401) is a critical Generation 3 wheel hub assembly designed for the rear axles of popular performance and All-Wheel Drive (AWD) sedans. These vehicles generate constant multi-directional stress through their drivetrains, requiring a hub unit with absolute rigidity to prevent handling instability. In our specialized assembly workshop, we reject the "ship-and-forget" mentality of massive factory lines. We physically touch, spin, and visually inspect the splined center bore and the integrated wheel studs on every single 512401 assembly. This meticulous human oversight guarantees that the CV axle will mate perfectly with the hub, ensuring smooth power delivery and eliminating annoying wheel hum for the end-user.
