Purpose and function in the BMW steering system

This steering rack with active steering is designed specifically for BMW E81, E87, E90, E91, and E92 models equipped with an active gear ratio system. It is responsible for transferring movement from the steering column to the front wheels, while working with the vehicle’s electronics to dynamically adjust the gear ratio based on speed and driving conditions.

By using the original BMW design, the following are maintained:

• consistency of the vehicle’s handling characteristics with factory settings,
• proper cooperation with safety systems (e.g., electronic stability control),
• appropriate rigidity and precision of response to steering input.

Construction and technical advantages of the steering rack

The steering rack belongs to the Steering racks and housings group, which means an integrated mechanism design with a housing adapted to the factory mounting points in the BMW body. This solution facilitates installation and reduces the risk of improper fitment with the suspension and steering column.

Key technical advantages of this sub-assembly include:

• original geometry and rack travel matched to the front axle suspension of the given BMW generation,
• adaptation for use with the active steering system, which improves maneuvering comfort in the city and stability at higher speeds,
• factory connection points for steering system accessories and suspension components.

Using the original steering rack with active steering allows for maintaining consistent, predictable vehicle handling, in accordance with the manufacturer’s specifications.

Condition, origin, and fitment

The offered BMW steering rack is a used item, sourced from vehicle dismantling. Such sub-assemblies are frequently chosen for post-accident repairs or when replacing a worn-out rack, where the priority is to maintain the original specification at reasonable service costs.

To ensure proper fitment for a specific vehicle, it is recommended to do the following before purchasing:

• compare the OEM part number with the number on the old steering rack,
• verify if the car is equipped with an active steering system,
• consult the selection of the component with a mechanic or a service center specializing in the BMW brand.

Choosing the correct steering rack has a direct impact on driving safety and the proper operation of driver assistance systems.

Application in service and steering system upgrades

The steering rack with active steering is suitable for both standard replacement of a worn-out component and more extensive service work within the front suspension and steering system. Replacing it with an original sub-assembly allows for restoring factory driving sensations, eliminating play, uneven steering resistance, or improper self-centering after a turn.
