Differential Purpose and Function

The presented rear differential is designed for installation on the vehicle's rear drive axle, where it compensates for differences in wheel rotational speed when cornering and ensures stable power transfer in both road and off-road conditions. The applied gear ratio provides balanced acceleration, cruising speed, and fuel consumption parameters, which is particularly important for mixed usage – city, highway, and utility.

Construction and Technical Properties

This differential belongs to the Differentials - Diffs group, which are components of the drive axle responsible for torque distribution. The design by Ford ensures:

• stable torque transfer to the rear wheels across a wide range of loads,
• proper integration with the factory drivetrain of the Ford Ranger 2.2 TDCI,
• maintaining predictable vehicle behavior during acceleration, engine braking, and when carrying loads.

Its placement at the rear means the component is installed in the rear part of the drivetrain, in the drive axle, replacing the factory differential specified by the manufacturer.

Selection, Compatibility, and Application

To correctly select this differential for a specific Ford Ranger model, it is recommended to verify compatibility using the OEM part number and interchangeable numbers, as well as comparing the gear ratio with the vehicle's factory specifications. The correct gear ratio selection directly impacts:

• acceleration characteristics – particularly important when driving with a load or off-road,
• engine RPM at cruising speeds – affecting acoustic comfort and driving economy,
• operation of assistance systems (e.g., traction control systems), which rely on factory drivetrain parameters.

If you have doubts about selecting the gear ratio and compatibility with a specific Ford Ranger drivetrain version, it is advisable to seek expert support. You can find a detailed discussion on this topic in the article Used Drive Axles and Differentials – How to Choose Gear Ratios for Your Driving Style, which describes practical examples and selection principles.

Condition, Origin, and Installation Recommendations

The offered differential is a used part, meaning it comes from a vehicle that was in operation and subsequently dismantled. Such components are often chosen by workshops and individual users as an economical alternative to new parts, while retaining the original manufacturer's design.

Before installation, standard servicing procedures are recommended, such as:

• verification of play and bearing condition by an experienced workshop,
• leak testing and inspection of sealing surfaces,
• changing the differential oil according to the vehicle manufacturer's recommendations.

Professional installation by a specialized service center allows you to fully utilize the potential of a used differential and minimize the risk of drivetrain malfunction.

Why Choose This Ford Differential

By choosing the Ford Ranger 2.2 TDCI Rear Differential Axle 3.55 AB39-4001-BBE, you gain:

• original Ford design – tailored to the specific model and drivetrain version,
• consistency with the vehicle's factory characteristics – without the need to modify other drivetrain components,
• a sensible compromise between performance and economy thanks to the appropriately selected gear ratio,
• an attractive cost-effective solution compared to purchasing a new axle or complete drivetrain.
