Mercedes-Benz W176 (A-Class) Electric Steering Rack | Genuine OEM Steering Gear

Description

The W176 utilizes an Electric Power Steering (EPS) system, where the steering rack itself houses the motor and controller responsible for your steering assistance. If you are experiencing “heavy” steering, “notchy” feedback when turning, or persistent “Steering Assist Malfunction” warnings on the dash, the internal motor or rack sensor may be failing.

We provide workshop-vetted, original Mercedes-Benz steering racks for the 2014–2018 W176 chassis. These units are a far more reliable solution than aftermarket “refurbished” racks, which often suffer from steering angle sensor misalignment or early electronic motor burnout.

• Factory-Spec Assistance: Calibrated to deliver the precise level of steering weight and responsiveness characteristic of the A-Class chassis.

• Electronic Integrity: Our units are verified for flawless communication with the vehicle’s Stability Control (ESP) and steering angle sensors, preventing persistent “malfunction” error codes.

• Condition: Premium workshop-vetted original component; inspected for rack straightness, zero internal play, and confirmed electronic motor functionality.

Signs Your Steering Rack Needs Replacement:

• Steering “Knocking”: A mechanical clunking or clicking sound felt through the steering wheel when going over bumps or turning at low speeds.

• Loss of Assist: The steering suddenly becomes very heavy, often accompanied by an “EPS Inoperative” or “Steering Assist Malfunction” message.

• Unusual Resistance: The steering feels “notchy” or tight in specific spots while turning, indicating worn internal components.

• Uneven Tire Wear/Alignment Issues: If the rack is damaged, you will often find it impossible to perform a proper wheel alignment, as the tie-rod adjustment cannot compensate for play in the rack itself.

Workshop Pro-Tip: Never replace the steering rack without a diagnostic scan. Sometimes, what looks like a failed steering rack is simply a communication fault caused by a bad ground connection or an issue with the Steering Angle Sensor (SAS). After installing the replacement rack, you must use a diagnostic tool to perform the “Start-up” or “Calibration” procedure. Failure to do this will result in a steering wheel that is off-center and an ESP system that will trigger errors during every turn!
