Purpose and Function in the Drivetrain

The presented flange operates in the rear section of the vehicle, in the area of the differential responsible for distributing torque to the rear axle wheels. Its function is to provide a stable, axial connection for the power transmission components, maintaining correct geometry and operating clearances. In quattro-equipped vehicles, the proper condition of this sub-assembly is crucial for:

• maintaining smooth operation of the rear differential under load,
• reducing vibrations and noise in the drivetrain,
• ensuring proper cooperation with other components of the rear axle.

Technical Characteristics and Fitment

The flange is designed as a component compatible with the factory differential geometry used in selected versions of Audi A4 B8 and Audi A5 8T with four-wheel drive. The construction is prepared for operation in the rear of the vehicle, meaning it is adapted to the specific loads and operating conditions of the rear axle. This allows for maintaining proper gear meshing and stable guidance of the shaft and cooperating components.

The correct dimensional and shape fit of the flange to a specific differential type reduces the risk of improper installation, thereby minimizing the possibility of leaks, excessive play, or accelerated wear of cooperating parts.

Benefits of Using an Original Audi Part

Using a flange from the range of parts dedicated to the Audi brand helps maintain the structural integrity of the entire drivetrain. Key benefits include:

• Factory Fitment – compatibility with the rear differential design used in the specific quattro drivetrain type.
• Stable System Operation – proper torque transfer to the rear axle, without unwanted play and excessive stress.
• Precise Diagnostics Capability – unambiguous assignment of the part to a specific group of sub-assemblies facilitates the selection of other parts during repairs.

As a part from the Other Differential Parts category, this product is suitable for both routine repairs and for rebuilding a complete drivetrain after significant mechanical damage.

Condition, Installation, and Service Application

The flange is offered as a used part, which in service practice is often a beneficial solution for differential repairs where structural compatibility and the ability to maintain the original drivetrain configuration are important. Before installation, the standard service procedure is recommended, including:

• verification of mating surfaces for wear,
• checking the correctness of seating in the differential,
• inspection of operating clearances after the entire sub-assembly is put together.

A part prepared in this way can be used in both workshop repairs and restoration projects where maintaining the original performance characteristics of the rear drivetrain is important.

Selection by OEM Numbers and Support for Online Purchases

When selecting a rear differential flange for a specific Audi A4 B8 or A5 8T configuration, it is crucial to use OEM numbers and interchangeable part numbers assigned to the specific differential type. This helps avoid errors due to differences in gear ratios, drivetrain versions, or design changes introduced during production.
