Starting at $77.95, AutoBuffy stocks 1 wheel bearing & hub kits from SKP to fit the Bmw 850Ci. A wheel bearing & hub kit supports the wheel's rotation while carrying the vehicle's load; when it fails, metal-on-metal contact accelerates rapidly, making safe driving impossible and risking wheel separation if ignored.
Most modern Bmw 850Ci hub assemblies are a sealed, pre-greased, bolt-on unit — no press or specialized bearing packing required. The main decisions are whether the hub includes an integrated ABS wheel speed sensor ring (match your original), which axle position you need, and what quality grade fits your budget and expected service life.
| Option | Best for | What you get |
|---|---|---|
| Economy / Value Grade | High-mileage vehicles, short-term budget repairs, or secondary-use vehicles | Meets OE fit and function at the lowest upfront cost; shorter rated service life than premium options |
| OE-Equivalent / Mid Grade | Daily drivers needing a reliable, direct replacement without dealership pricing | Factory-spec bearing preload, matching ABS tone ring, and a balance of cost and longevity |
| Premium / Heavy-Duty Grade | High-mileage daily drivers, towing and hauling applications, or harsh-climate use | Higher-grade steel races, upgraded seals against water and road salt, longer manufacturer warranty |
| Front Hub Assembly (with sensor) | Vehicles with ABS — front axle replacement | Integrated wheel speed sensor connector; plug-and-play ABS compatibility, no separate sensor purchase needed |
| Rear Hub Assembly | Rear-wheel or all-wheel drive axle service on the Bmw 850Ci | Sized for rear bearing loads; may or may not include ABS sensor ring depending on vehicle configuration — verify before ordering |
After safely lifting and supporting the Bmw 850Ci and removing the wheel, unbolt the hub assembly from the steering knuckle and disconnect the ABS sensor harness before pulling the old unit free. Clean the knuckle mounting surface thoroughly, seat the new hub, and tighten the hub bolts and axle nut to the manufacturer's specification listed in your service manual — proper final torque on the axle nut is critical to bearing life. Reconnect the sensor harness, reinstall the wheel, lower the vehicle, and confirm the ABS warning light clears after a short test drive.
