Most modern vehicles are equipped with rack and pinion steering systems that are responsible for allowing you to have control behind the wheel of your Mercedes-Benz. There are many components that are present in these types of systems, including the steering rack or gearbox in the center. The steering rack is what gets input from you as a driver through the steering wheel and column. Signals then get sent to your tie rods and steering shafts so you can make turns efficiently. Over time, the gearbox or steering rack can become worn out and might need to be repair or replaced. There are some things you might notice that can signal you to an issue with this part of your vehicle. You also could notice your car leaking power steering fluid, which can be a sign of a broken gasket or loose fitting. If you need a replacement steering rack or gear box, be sure to invest in an OEM one for your Mercedes-Benz. We sell them here.
