Audi TT VW Touran Wheel Hub Rear Left N/S Steering Knuckle Brake Disc 5QA505433B

Audi TT VW Touran Wheel Hub Rear Left N/S Steering Knuckle Brake Disc is a component from the Wheel bearings, hubs and bushings group, designed for installation in the rear left part of the suspension. This solution allows for the restoration of proper axle geometry, stable handling, and safe wheel operation in VAG group vehicles. Thanks to its factory design, the steering knuckle with hub ensures proper bearing seating and secure mounting of suspension and braking system components.

Purpose and vehicle placement

The presented steering knuckle with hub operates in the rear suspension area on the left side. It is responsible for stable wheel guidance, transferring loads from the control arms and shock absorber, and maintaining the correct position of the hub relative to the body. A properly selected component in this location is crucial for:

• maintaining rear axle geometry in terms of toe and camber,
• even tire wear and predictable vehicle behavior,
• secure mounting of the hub, bearing, and brake components.

Construction and technical function

The steering knuckle integrated with the hub constitutes a rigid structural node of the rear suspension. Its main tasks include:

• ensuring axial wheel guidance relative to the body,
• transferring longitudinal and lateral forces from the road to the chassis,
• stable seating of the wheel bearing and cooperation with the braking system.

Thanks to its factory geometry, the component works with standard control arms, springs, and shock absorbers, which facilitates installation and subsequent toe adjustment. Precise fitment to the Audi/VW platform reduces the risk of incorrect suspension alignment and associated vibrations or vehicle pulling.

Application in Audi and VW

The rear left axle steering knuckle with hub is used in Audi and Volkswagen models based on a shared suspension architecture. In practice, this means the component can be used both for standard replacement of a worn steering knuckle and for post-accident repairs where restoring factory body and axle geometry is necessary.

Wheel bearings, hubs and bushings in this group of vehicles are designed for high rigidity and durability, which is why using the original design allows for maintaining the handling characteristics intended by the manufacturer. This is particularly important in cars such as the Audi TT, where handling precision and stability at higher speeds are of great significance.

Benefits of choosing an original used component

Choosing a used steering knuckle with hub is a solution that allows you to combine cost control with maintaining the factory design. This type of component is particularly attractive for suspension repairs where the following are important:

• dimensional compatibility with factory mounting points,
• possibility of installing standard bearings and accessories,
• restoration of original suspension geometry without modifications.
