Listing details

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

Ford Transit Mk8 2.0D Rear Axle Differential Diff RWD GK31-4001-FAH WARRANTY is a complete, used rear axle drivetrain assembly designed for rear-wheel-drive vehicles. This component is responsible for transferring torque from the driveshaft to the wheels and properly distributing power between the left and right sides, which is crucial for the stability and predictable handling of the Transit. Thanks to Ford's factory design, this solution is technically matched to the specifics of the 2.0 EcoBlue unit and the Mk8 body characteristics.

Purpose and function of the rear axle

The presented rear axle with differential is designed to operate in an RWD system, i.e., rear-wheel drive. Its rear placement on the vehicle ensures proper loading of the drive axle, which translates into stable vehicle behavior both when loaded and when driving with an empty cargo space. This assembly is responsible for:

• mechanical connection of the driveshaft to the rear wheel hubs,
• compensating for the difference in wheel rotational speed during cornering,
• maintaining the correct gear ratio between the engine and the wheels.

Thanks to Ford's factory design, the axle works in harmony with the Transit Mk8's suspension and braking system, ensuring predictable vehicle reactions and consistent traction parameters.

Benefits of using an original Ford differential

Choosing an original differential from the Differentials category allows you to maintain compliance with Ford's factory design specifications. This means:

• proper fitment to frame mounts and suspension components,
• maintaining the factory axle ratio, which affects dynamics, fuel consumption, and gearbox operation,
• compatibility with vehicle safety systems, such as ABS or ESP (if present in the specific configuration).

A used rear axle assembly is a solution that allows for cost-effective drivetrain repair while maintaining the original handling characteristics and operating loads intended by the manufacturer.

Application in Ford Transit Mk8 2.0 EcoBlue RWD

The rear axle with differential has been developed with the specifics of the Ford Transit Mk8 with a 2.0 EcoBlue engine and rear-wheel drive in mind. This configuration is often chosen for commercial vehicles due to its favorable weight distribution and good torque transfer under heavy loads. Using the correct rear axle has a direct impact on:

• smooth starting under load,
• stability at higher speeds,
• even tire wear on the drive axle.

By maintaining factory geometry and gear ratios, the vehicle retains the performance parameters intended by the manufacturer, which is important both in daily fleet work and individual use.

Characteristics of the used rear axle

The offered item is in used condition, meaning it has been removed from a vehicle and verified for further operational suitability. This type of solution allows for reduced repair costs while maintaining the original Ford design. The rear axle with differential is particularly recommended in situations where:

• mechanical damage to the existing axle has occurred (e.g., after a collision or overheating),
• there are noticeable noises from the rear axle area indicating gear wear,
• a quick replacement of the complete assembly is necessary instead of time-consuming repair of individual components.

Choosing a complete, used rear axle with differential reduces vehicle downtime and simplifies the service process, as many workshops prefer replacing the entire assembly rather than refurbishing individual components.

Gear ratio selection and additional technical materials

When replacing the rear axle, it is crucial to match the gear ratio to the specific version of the Ford Transit and the vehicle's usage style. Proper selection affects engine RPM at a given speed, flexibility under load, and acoustic comfort. To better understand the relationships between axle ratio, engine characteristics, and commercial vehicle use, it is worth reading our guide: Dismantled drive axles and differentials – how to choose gear ratios for your driving style.
