Purpose and function in the drivetrain

The described drive axle is a component mounted on the rear axle of the vehicle, responsible for distributing torque to the wheels and changing the gear ratio between the driveshaft and the wheel hubs. The applied 2,47 ratio promotes smoother, more economical driving while maintaining appropriate dynamics, which is particularly beneficial in W204, W205, and W212 class cars used both on the highway and in daily city traffic.

Choosing a differential with the correct gear ratio has a direct impact on:

• engine RPM at highway speeds,
• throttle response and flexibility during acceleration,
• acoustic comfort in the cabin,
• fuel consumption under typical operating conditions.

Compatibility and interchangeable numbers

The axle has been designed as a component compliant with Mercedes factory requirements and features a dedicated OEM part number and a set of interchangeable numbers, which facilitates matching to specific body and engine versions. This makes it possible to use the differential in various variants of W204, W205, and W212 models, provided there is compatibility in the gear ratio and drivetrain configuration.

Before purchasing, it is worth comparing the markings from the old axle's identification plate and the vehicle's catalog data – this helps avoid installation problems and ensures proper cooperation with the existing driveshaft and half-shafts.

Performance characteristics and advantages of use

Choosing this differential is a solution for users who expect stable drivetrain operation and predictable vehicle behavior in various road conditions. Key benefits include:

• factory 2,47 gear ratio – maintaining the original driving characteristics intended by the manufacturer,
• proper cooperation with the vehicle's electronic systems (e.g., ESP, ABS, traction control systems),
• possibility of use as a replacement for a worn or damaged axle without interfering with the body structure,
• maintaining proper geometry and drive alignment thanks to the original housing and mounting points.

The component comes from a used vehicle, which in practice means a favorable price-to-functionality ratio while maintaining the original build quality characteristic of the Mercedes brand.

Installation and technical aspects

The 2,47 differential is intended for installation on the rear of the vehicle, in place of the factory differential. During replacement, it is recommended to:

• check the condition of the axle mounts and suspension bushings,
• verify the tightness of connections and the condition of the half-shafts,
• use the appropriate transmission oil in accordance with the vehicle manufacturer's recommendations,
• check for play and perform a geometry alignment after the work is completed.

A properly selected and installed differential reduces the risk of noise from the rear of the car, vibrations during acceleration, and uneven tire wear. This is especially important in premium class cars, where high drivetrain refinement is expected.

Drivetrain expansion and gear ratio selection

If you want to better understand how the 2,47 ratio affects your Mercedes' driving characteristics and how to choose an axle for a specific driving style, it is worth consulting specialized materials. Practical tips, configuration examples, and a discussion of the differences between used and remanufactured axles can be found in the article Dismantled drive axles and differentials – how to choose gear ratios for your driving style.
