Purpose and function in the vehicle

The rear right knuckle in the Audi Q5 FY 2.0 TFSI DAXB is responsible for the precise positioning of the wheel hub relative to the control arms and other suspension components. A correctly selected part:

• maintains proper wheel camber and toe angles,
• stabilizes suspension operation under load and in corners,
• reduces excessive tire wear resulting from incorrect geometry,
• supports the proper functioning of safety systems dependent on axle geometry.

Thanks to its adaptation to the 2.0 TFSI petrol unit, the knuckle works in harmony with the mass distribution and load characteristics typical of this powertrain configuration.

Benefits of using an original knuckle

Using a knuckle dedicated to the Audi Q5 FY allows you to maintain the factory handling parameters of the vehicle. The original design ensures:

• precise fitment with suspension components without the need for modifications,
• compatibility with factory mounting points for control arms, hubs, and accessories,
• repeatability of geometry settings after installation and adjustment,
• stable vehicle behavior at higher speeds and during emergency maneuvers.

This solution is particularly recommended for post-collision repairs, replacement after mechanical damage, or when there are noticeable issues with maintaining the vehicle's driving path.

Installation characteristics

The knuckle is designed for installation on the rear right side of the suspension, replacing the factory component. The design intended for a specific model version facilitates service work because it:

• allows the use of standard mounting points,
• is compatible with the factory rear axle suspension system,
• enables proper seating of the hub and associated components.

After installation, it is recommended to perform a geometry alignment to fully utilize the potential of the newly installed knuckle and restore proper handling parameters.

Application in petrol vehicles

The component is designed to work with a powertrain based on a petrol engine, which means it is matched to the specific weight distribution and suspension operating characteristics of this version. As a result, the knuckle supports:

• even load distribution on the rear axle,
• body stability during dynamic driving,
• driving comfort typical of Audi Q5 FY petrol configurations.

Supplementing the Audi suspension system
