Purpose and function of the rear differential

The presented rear axle with differential is a component from the Differentials category, responsible for distributing power to the rear axle wheels in the quattro system. The applied 47:11 gear ratio is matched to the characteristics of the 2.0 TDI DETA unit, which allows for maintaining proper engine RPM at various speeds and consistency with the factory drivetrain control software.

Its location on the vehicle's rear axle means this component has a direct impact on:

• traction during acceleration on surfaces with varying grip,
• vehicle stability in corners during dynamic driving,
• even torque distribution to both rear wheels.

Benefits of using an original rear axle with differential

Using an original Audi rear differential in the A4 B9 2.0 TDI DETA Quattro model allows for maintaining the factory performance parameters of the drivetrain. The correct gear ratio and fitment for the specific drivetrain configuration reduce the risk of malfunctions in assistance systems, such as traction control or electronic stability control.

The main advantages of this solution include:

• consistency with factory acceleration characteristics and engine RPM,
• proper cooperation with the front-wheel drive and the central torque distribution system,
• maintaining predictable, neutral vehicle handling.

Characteristics of the used component

The offered rear axle with differential is a used component, sourced from vehicle dismantling, which provides an attractive cost alternative to new parts. Such components are frequently chosen for post-accident repairs, replacements after mechanical damage, or when it is necessary to match the gear ratio to a specific drivetrain configuration.

Choosing a used rear differential allows you to:

• reduce repair costs while maintaining the original design,
• maintain compliance with factory gear ratio parameters,
• avoid issues with fitting mounting elements specific to a given model.

Matching to driving style and drivetrain configuration

The 47:11 gear ratio used in this rear axle is a crucial parameter when selecting a differential for a specific Audi A4 B9 2.0 TDI DETA Quattro. It influences the car's throttle response, engine RPM at highway speeds, and overall driving comfort. When replacing a differential, it is key to ensure the gear ratio is compatible with the other drivetrain components to avoid overloads and improper operation of the all-wheel-drive system.
