Mercedes-Benz Steering Problems
For control, safety, comfort, and overall driving experience, your Mercedes-Benz steering system is essential. And in order to maintain the reputation of its brand, Mercedes-Benz places a high premium on the quality and performance of its steering.

We have a highly skilled team of Mercedes experts at Marc’s Garage to handle any steering problems. So if you hear strange sounds, have trouble controlling your car, and need steering diagnostics and repairs, reach out to our team today.
This blog explains how the steering system works, why it needs to be maintained, and what could cause a grinding or whining noise.
Let’s explore the possible causes in more detail.
Mechanics of the Mercedes Steering System
As with most modern vehicles, Mercedes-Benz includes a power-assisted steering system to improve the driver’s control and comfort. The specific mechanism of a power-assisted steering system can vary based on the model and technology, but the following is a general overview:
Steering Wheel: The steering wheel is used to change the direction of the vehicle.
Steering Column: A shaft connected to the steering column rotates as the driver turns the steering wheel.
Steering Gearbox: Older Mercedes models may have hydraulic power steering gearboxes. However, in many modern vehicles, Mercedes uses an electric power steering (EPS) system. In an EPS system, an electric motor assists you with steering instead of hydraulic pressure. The vehicle’s computer controls this motor.
Steering Sensors: Various sensors, including the steering angle sensor and vehicle speed sensor, continuously monitor the driver’s steering inputs and speed of the vehicle. The vehicle’s control unit receives important data from these sensors.
Control Unit: Data from the sensors is processed by the control unit to calculate the amount of steering assistance required. By adjusting the electric motor’s output, it provides the appropriate level of assistance, which can vary depending on the vehicle’s speed, weather and driving conditions.
Assistive Force: Electric motors provide additional steering assistance to drivers. This assistance makes turning the steering wheel easier, especially at low speeds or when parking. The system may reduce assistance at higher speeds to improve driver control and stability.
Safety Features: The steering system of Mercedes-Benz vehicles is also equipped with a number of safety features. As an example, lane-keeping assist, adaptive steering and various driver assistance systems can help keep the vehicle in its lane, maintain a safe following distance, and assist with parking.
Whether hydraulic or electric, Mercedes steering systems are designed to enhance driver comfort, control and safety. The vehicle adapts to different driving conditions and assists the driver as needed while maintaining a connection with the road to ensure a premium driving experience. However, It is important to remember that specific technologies and features may differ between models and years of Mercedes-Benz.
Common Mercedes-Benz Steering Noise Causes
When driving your Mercedes-Benz, you might hear unusual noises that indicate a problem with the steering. The following are some of the most common causes of steering noise in Mercedes-Benz vehicles:
- Low Power Steering Fluid: Insufficient power steering fluid can cause the steering wheel to whine or groan.
- Worn Power Steering Pump: When the power steering pump fails, it can cause noise. You may hear whining or squealing if your power steering pump wears out or fails.
- Damaged Power Steering Hoses: Damaged or cracked steering hoses can cause fluid leaks, leading to steering problems and noise. When a hose leaks, a hissing sound may be heard.
- Steering Rack or Gearbox Issues: When steering, clunking or knocking noises can be caused by problems with the steering rack or gearbox. These components will need to be inspected and possibly replaced.
- Ball Joint or Tie Rod Wear: When turning the steering wheel, worn ball joints or tie rod ends can make clunking or clicking sounds. These components connect the steering system to the wheels for proper steering control.
- Tyre Issues: Tyre wear that is irregular or damaged can cause noise during steering manoeuvres. Inspect your tyres regularly and make sure they are inflated to the recommended levels.
- Lubrication: There can be a creaking or squeaking sound when various steering components lack lubrication, such as the steering column or universal joints.
- Faulty Steering Column: Occasionally, steering noise can be caused by a problem within the steering column itself, such as a loose or damaged component.
If you are experiencing steering noises in your Mercedes-Benz, we recommend speaking with a qualified technician, like the Mercedes experts at Marc’s Garage. In order to identify the exact source of the noise, our mechanics will carry out a comprehensive inspection, ensuring that any necessary repairs or maintenance are carried out correctly. Leaving steering noise unattended can lead to more serious issues and compromise vehicle safety.
Is It Safe to Drive With Strange Steering Noises?
If you hear strange noises while steering your Mercedes, you should stop immediately, especially if the noise is accompanied by steering changes or dashboard warning lights. It can be dangerous to continue driving under these conditions and could result in more serious consequences.
You should instead consult a mechanic, like the Mercedes experts here at Marc’s Garage, to determine whether it’s safe to drive or if immediate repairs are needed. As a top priority, safety should always come first.
