Purpose and function of the wheel hub

The rear hub in BMW F40, F44, and F45 series models, as well as in the X1 F48 and X2 F39 SUVs, is responsible for stable wheel mounting and transferring loads from the road surface to the suspension. Its placement on the vehicle covers the rear axle, both on the right and left sides, allowing for flexible application depending on service requirements.

This component works in conjunction with other suspension and braking system parts, influencing:

• maintaining proper wheel geometry on the rear axle,
• even tire wear,
• driving comfort at higher speeds,
• vehicle stability during braking and cornering.

Benefits of using an original BMW hub

Using an original BMW wheel hub as part of Suspension repair kits allows you to maintain the parameters specified by the vehicle manufacturer. Proper fitment to the steering knuckle, brake disc, and other chassis components minimizes the risk of vibrations, noise, and geometry issues.

The main advantages of this solution include:

• factory fitment for specific BMW F-family models,
• consistent performance with the rear multi-link suspension,
• versatility for use on either the left or right side, which simplifies repair planning,
• preservation of the handling characteristics typical of BMW.

Vehicle placement and service application

The hub is designed for installation on the rear axle on the left or right side, which allows it to be used both for single-sided repairs and for replacing both sides during a single service process. This approach is particularly beneficial for comprehensive suspension maintenance when other components from the same group are also being replaced.

In workshop practice, the BMW rear hub is often installed when:

• eliminating play and knocking sounds in the rear suspension,
• performing repairs after collisions or mechanical wheel damage,
• preparing the car for a technical inspection or a long trip.

The hub in the context of the suspension system

As an element of the Suspension repair kits category, the wheel hub works with shock absorbers, control arms, and stabilizers, creating a cohesive system responsible for safety and driving comfort. A correctly selected hub reduces the risk of improper wear of rubber-metal components and improves steering precision.

If you want to better understand how the hub fits into the operation of the entire suspension and how to maintain this system in modern cars, it is worth reading our guide: Suspension system – a comprehensive guide to shock absorbers, control arms, and stabilizers.

Selecting parts by BMW numbers and brand

The offered hub is an original BMW part, which facilitates its identification by catalog numbers and matching it to a specific body and engine version. In service practice, this reduces the risk of ordering errors and speeds up the installation process.
