Used BMW iX Wheel Hub

The BMW iX (U11 platform) launched in the UK for the 2022 model year and is the first and only generation to date, with no confirmed major facelift boundary yet established that is known to affect running gear. Wheel hub design is tied to the drivetrain and brake specification rather than cosmetic updates, so for now all UK iX models share the same generation platform. Always confirm the exact hub specification with the breaker against your registration number to be safe.

This is where fitment becomes uncertain and you should not assume interchangeability: the xDrive50 and M60 variants produce significantly more power and torque than the xDrive40, and BMW typically fits larger brake assemblies and uprated hub carriers to higher-output variants to handle the increased loads. The hub flange, bearing specification, and bolt pattern may differ between the xDrive40 and the heavier-duty setups on the xDrive50 and M60. Confirm which drivetrain variant the donor hub came from with the breaker before purchasing.

Trim level does not affect wheel hub fitment on the BMW iX — Sport, xLine, and M Sport are specification packages relating to cosmetics, interior, and suspension tuning rather than hub design. The hub itself is determined by the drivetrain variant (xDrive40, xDrive50, M60) and which corner of the car it came from, not the trim badge. Do bear in mind that different trims may run different wheel sizes, so check your wheel and brake setup matches the donor car rather than just the trim name.

Yes, it matters significantly — NS (nearside, left) and OS (offside, right) hubs are handed components and are not interchangeable. When sourcing from a breaker, always specify which side you need alongside the drivetrain variant to avoid being sent the wrong part. Double-check the side when the part arrives before attempting fitment.

Provided the donor vehicle is the same drivetrain variant (e.g. xDrive40 to xDrive40) and the same corner of the car, mileage and age differences within the current iX generation should not affect physical fitment of the hub itself. However, if BMW made any running production changes to the hub or bearing specification during the model's life, a breaker may be aware of these — so confirm the part number from the donor car against your own registration when you get your quote. Findapart breakers can look this up for you before the part is dispatched.

On modern BMW models including the iX, the wheel bearing is typically pressed into or integrated with the hub carrier, and many breakers supply the complete hub assembly rather than the bare bearing alone — this is often the more practical repair on these cars. Whether you can replace the bearing independently or need the full hub will depend on your workshop's equipment and the condition of the existing hub. Confirm with your mechanic first, then let the breaker know exactly what assembly you need so they can quote accordingly.
