The suspension system in your Mercedes-Benz is complex and made of a variety of components that all help to stabilize your vehicle when you're traveling on the road. The sway bar is a part featured on some suspension systems that is designed to prevent your car from leaning to the side one way or another. The sway bar will work if your car starts leaning to the side (usually when it's turning). When your car does this, it will apply force to your suspension on both sides so that it can resist leaning. If you have a sway bar installed, it has the potential to wear out over time. It's important to pay attention to signs that your sway bar bushing or links are going bad. If you experience clunking or rattling noises on the road, this could be a sign of issues. Noise going over speed bumps can also indicate problems.
