Purpose and function in the suspension

The rear right control arm in the Audi A4 B9 is responsible for the precise guidance of the wheel relative to the body, maintaining specified camber and toe angles, and transferring loads from the road surface to the vehicle structure. A correctly selected component from this group minimizes unwanted wheel movement, reduces tire wear, and improves stability during dynamic driving.

Thanks to its dedicated placement in the rear axle zone on the right side, the control arm works in conjunction with other suspension components to create a cohesive system responsible for comfort, grip, and driving safety.

Benefits of using an original Audi control arm

Using an original control arm in the Audi A4 B9 ensures:

• precise fitment to the mounting points on the body and steering knuckle,
• preservation of the vehicle's factory handling characteristics,
• proper cooperation with other components from the Control arms and ball joints group,
• stable vehicle behavior during load changes and on uneven surfaces.

This solution is particularly beneficial for post-collision repairs, replacing worn suspension components, or restoring factory geometry parameters after long-term operation.

Vehicle placement and installation aspects

The precisely defined vehicle placement – rear, right side facilitates the selection of the correct component during repair. Installation is carried out at factory mounting points, which allows for the maintenance of the suspension kinematics intended by the manufacturer and facilitates subsequent wheel geometry adjustment.

After installation, it is recommended to perform a professional wheel alignment and camber adjustment to fully utilize the potential of the newly installed control arm and ensure even tire wear.

Condition and service application

The item comes from the used Audi parts segment, which allows for economical repair while maintaining a design consistent with the manufacturer's specifications. This type of component is often chosen by professional workshops specializing in the Audi brand, where both technical compliance and optimization of vehicle maintenance costs are prioritized.
