Technical Characteristics of the Steering Rack

Benefits of Using an Original Electric Steering Rack

Using an original electric power steering rack in the Sprinter W907 helps maintain the consistency of the entire drivetrain. Compared to aftermarket alternatives, an OEM part ensures:

• stable and predictable vehicle behavior under typical load conditions for commercial vehicles,
• maintenance of factory steering force characteristics,
• reduced risk of electronic compatibility issues and errors in driver assistance systems.

For fleets, vehicles used in transport, and custom-built vehicles (e.g., refrigerated vans, campers), this is important not only for operational but also for economic reasons – a correctly selected steering rack reduces wear on other steering and suspension components.

Condition, Verification, and Preparation for Installation

The steering rack comes from the used original parts segment. These types of components are often chosen as a sensible compromise between cost and maintaining factory quality. Before installation, a standard workshop inspection is recommended, including checking for mechanical play, leaks, and the correct operation of the electric power assistance in conjunction with the vehicle's electrical system.

Due to the specific nature of the electric power steering system, it is advisable to entrust the installation to a service center experienced with Mercedes Sprinter W907 vehicles. This will ensure proper connection, potential adaptation in the diagnostic system, and preservation of the steering system's full functionality.

Application in the Sprinter W907 Steering System

• ease of maneuvering in the city and in parking lots,
• confidence in handling at higher speeds,
