Listing details

The differential is sold with a 90-day warranty! It was tested before removal and is in full working order.

Mercedes V177 W247 4-Matic Rear Differential Axle is a factory drivetrain component designed for installation on the rear axle of Mercedes vehicles. It is responsible for the precise transfer of torque to the wheels and proper power distribution, which translates into stable handling and predictable vehicle behavior. By maintaining the original design and specific gear ratio, it ensures consistent operation with other drivetrain components.

Technical characteristics and function in the drivetrain

The presented rear axle is a component from the Differentials group, operating in the rear axle area of the vehicle. Its purpose is to:

• transfer power from the driveshaft to the rear wheels while maintaining the specified final drive ratio,
• compensate for the difference in wheel rotational speed when cornering,
• maintain proper traction and vehicle stability at various speeds.

Its location in the rear axle zone allows for direct interaction with the suspension and drivetrain, which is important for ride comfort and predictable handling. A properly selected differential ratio affects acceleration characteristics, flexibility, and engine RPM at highway speeds.

Application in Mercedes vehicles and benefits of installation

The differential is intended for Mercedes models from the V177 / W247 family, where the rear axle plays a key role in power transmission. Using an original rear axle allows you to maintain:

• consistent operation with factory electronics and driver assistance systems,
• correct gear ratios selected by the manufacturer for the vehicle's weight and engine power,
• stable vehicle behavior during dynamic maneuvers and when driving under load.

For the user, this means predictable throttle response, repeatable behavior in corners, and a reduced risk of improper interaction with traction control or electronic stability systems.

Condition, origin, and installation aspects

The offered rear axle is a used component, which allows for an economical repair of the drivetrain while maintaining the manufacturer's original design. This type of component is particularly attractive in situations where:

• mechanical damage to the differential has occurred (e.g., after a collision or overload),
• there are noticeable noises coming from the rear part of the drivetrain,
• it is necessary to replace the complete axle instead of performing costly repairs on individual components.

The location on the rear axle makes it easier for technicians to plan installation work – the differential is removed as a whole, which shortens repair time compared to disassembling and adjusting individual gears. Choosing an original component from dismantling reduces the risk of problems with mounting fitment and compatibility with the existing suspension.

Gear ratio selection and vehicle compatibility

When replacing a differential, it is crucial to match the gear ratio to the drivetrain and transmission configuration. Incorrect selection may result in changed driving characteristics, errors in electronic system operation, or uncomfortable drivetrain performance. To better understand the relationship between axle ratio, driving style, and vehicle parameters, it is worth reading the guide: Dismantled drive axles and differentials – how to choose ratios for your driving style.

Support with selection and additional information

If you are planning a comprehensive repair or upgrade of the drivetrain area in your Mercedes and need other components from the same group, such as complete axles, final drives, or other rear differentials, check the available parts in the Mercedes Differentials category.

When choosing a used differential, many people consider whether to stick with dismantled parts or invest in new components. The differences in costs, durability, and availability are discussed in detail in the article: Car parts – new or used? Comparing costs, quality, and durability. This makes it easier to make an informed decision tailored to your budget and expectations for the vehicle.
