Purpose and function in the suspension

The wheel carrier integrated with the trailing arm on the rear left side is responsible for proper wheel guidance, maintaining specified camber and toe angles, and stable transfer of loads from the road to the body. In combination with the hub and bearing, it forms a key node of the chassis, affecting:

• driving stability at higher speeds,
• even tire wear,
• precision of steering response,
• effective cooperation with traction control systems and the ALL4 drive. The placement on the vehicle defined as rear – left side facilitates clear identification of the part during selection and installation.

Benefits of using an original Mini component

Using a wheel carrier with a trailing arm from the Bearings, wheel hubs and bushings group dedicated to Mini allows for maintaining factory suspension performance parameters. The original geometry of the mounts and attachment points means:

• secure fit to the body and other suspension elements,
• no need for modifications or adjusting mounting holes,
• easier geometry adjustment after installation,
• consistency with factory settings of the ALL4 drivetrain. This solution is particularly beneficial for post-accident repairs and when replacing worn or corroded rear suspension components.

Used condition and installation aspects

The item is offered in used condition, which allows for reducing repair costs while maintaining a design consistent with Mini's factory specifications. Before installation, it is recommended to perform a standard verification of mounting surfaces, bearing seats, and points of contact with bushings and the wheel hub. After installation, it is necessary to set the rear axle wheel geometry to fully utilize the suspension's potential and ensure even tire wear.

Application in the ALL4 system

In the Countryman R60 model with ALL4 drive, the rear wheel carrier with trailing arm works with the drivetrain, so its proper fit is important for the operation of the entire system. A correctly selected and installed component:

• supports the proper operation of the all-wheel drive,
• reduces unwanted vibrations and play in the rear part of the vehicle,
• ensures predictable vehicle behavior on surfaces with varying grip.
