The steering system in your Mercedes-Benz is something you want to be sure is operating efficiently so you can maintain control behind the wheel. The steering system is made of a lot of different parts, including your steering rack, the column, and the wheel itself. Everything has the potential to wear out over time and need replacement at a point. It's important to pay attention to how your steering wheel feels when you use it so you can make replacements as soon as possible. You can put yourself at risk on the road if your steering wheel isn't functioning as you need it to. If your steering wheel is feeling too stiff or loose, this can be a sign of wear and tear on your vehicle. Another part of your steering wheel is your horn, which helps you to communicate to other drivers on the road if needed. The horn relay can wear out and result in a non-functioning horn. If you need a new steering wheel or horn relay, you can find OEM ones here for Mercedes-Benz models.
