Vehicle Application and Function

This component is designed for the rear right side of the BMW 1 Series Coupe E82 and Convertible E88 models, specifically the 123d variant with the N47S engine. This assembly is responsible for stable wheel guidance, transferring loads from the body to the road, and precisely maintaining the suspension geometry on the rear axle.

Combining the hub, knuckle, and braking components into a single module reduces the risk of mismatched parts and facilitates correct wheel alignment after repair. This solution is particularly beneficial for damage resulting from collisions, intensive use, or corrosion of structural elements.

Suspension and Brake Assembly Construction

The complete assembly includes key components responsible for wheel guidance and effective braking. In one module, you receive:

• suspension hub with wheel mounting,
• steering knuckle with mounting points for control arms and shock absorber,
• brake caliper adapted for the factory braking system of the BMW 123d,
• brake discs matched to the installed caliper.

This configuration promotes structural integrity of the rear axle while simplifying the service process – a mechanic deals with one complete sub-assembly instead of multiple individual parts.

Benefits of Using an Original BMW Assembly

An original BMW suspension and brake assembly ensures factory fitment to the rear axle geometry, which translates to predictable vehicle handling and stability at higher speeds. Using a component from the same model line minimizes the risk of installation issues and the need for additional modifications.

Key advantages of this solution include:

• structural consistency – all components operate within the manufacturer's specified parameters,
• easier diagnostics and service – one module instead of many individual parts,
• preservation of the characteristic handling of the BMW 1 Series,
• possibility of effective repair after mechanical or operational damage.

Practical Application in Service

The rear right hub, knuckle, and brake assembly is particularly useful in situations where multiple components have been damaged simultaneously – for example, after hitting a curb, a side collision, or prolonged operation in harsh road conditions. Replacing the complete module restores correct wheel guidance and uniform brake system operation on the right side.

This solution is also economically advantageous for workshops specializing in BMW, where assembly time and guaranteed fitment are crucial. The complete rear suspension assembly with brakes reduces potential points of error during repair and simplifies subsequent geometry checks.

Additional Technical Information and Support

This item belongs to the Suspension Replacement Kits group, meaning it is designed as an integrated module for rear axle service. If you have doubts about compatibility with a specific equipment version or vehicle year, it is advisable to verify the designations in the technical specifications and consult a BMW specialist mechanic.

To better understand the role of such sub-assemblies in the drivetrain and their impact on safety, you can refer to the advice in the article Suspension System – A Comprehensive Guide to Shock Absorbers, Control Arms, and Stabilizers, which discusses practical aspects of suspension operation and diagnostics in popular models.
