Purpose and function of the rear differential

The presented rear differential is a component of the drivetrain in Mercedes C-Class W203 generation and C209 model vehicles. It is responsible for distributing torque between the rear wheels and maintaining the correct gear ratio, which translates into smooth acceleration, stability at higher speeds, and predictable vehicle behavior in corners. The applied 2.47 ratio promotes a calmer, more economical driving style and lowers engine RPM during highway driving.

Construction and vehicle placement

The differential is designed as an integral rear axle, mounted in the rear part of the chassis along the vehicle’s longitudinal axis. The placement on the vehicle, defined as rear, means it works in conjunction with the rear half-shafts and rear axle suspension, which is crucial for the correct alignment of the drivetrain geometry and the durability of the entire system.

The axle construction is adapted to the factory mounting points in the Mercedes chassis, which facilitates installation and allows for maintaining the original driveshaft line and correct joint operating angles. As a result, the differential can be used as a direct replacement for the factory axle without the need for structural modifications.

Application in Mercedes vehicles

Mercedes Differentials of this type are used in rear-wheel-drive vehicles where precise matching of the gear ratio to the engine and transmission characteristics is required. The proper selection of a differential affects:

• dynamic yet predictable acceleration,
• acoustic comfort at higher speeds,
• driving stability during acceleration and deceleration,
• even load distribution on drivetrain components.

By choosing a Mercedes rear axle with the correct ratio, you restore the factory operating parameters of the drivetrain, which is particularly important after damage to the original differential or during a professional drivetrain repair.

Characteristics of the used product

The offered differential comes from dismantling and is marked as a used component. Such parts are frequently chosen for repairs where maintaining the original manufacturer’s specifications while optimizing costs is a priority. A used Mercedes rear axle, when properly selected and installed, allows for restoring correct drivetrain operation without the need to invest in a new component.

Before installation, a standard service procedure is recommended, including checking for leaks, operational backlash, and the condition of the gear oil to ensure long-term and stable system operation.

Gear ratio selection and additional technical information

The 2.47 ratio has a significant impact on driving characteristics – lower engine RPM at constant speeds promotes calm, economical operation and reduces cabin noise. When replacing the differential, always verify the compatibility of the ratio with the factory configuration of the specific vehicle to avoid irregularities in drivetrain operation and speedometer readings.

If you want to better understand the impact of the axle ratio on vehicle behavior, the selection of a differential for your driving style, and the differences between individual configurations, it is worth reading the guide: Dismantled drive axles and differentials – how to choose ratios for your driving style. The article discusses practical aspects of ratio selection, component compatibility, and common user questions.
