The power steering pump is an important part in your Mercedes-Benz. This component works to help send fluid from a reservoir to the steering gear, which helps you to be able to turn your wheels smoothly. The pump has to be working properly in order to help deliver the correct amount of pressure during this process. It's important that you're paying attention to how effectively your power steering pump is working so you can stay in control on the road. There are some symptoms to be on the lookout for that might indicate wear and tear on the pump. When you're turning the wheel of your car, if you start to hear whining noises, there could be a leak in the pump. Pay attention to how your steering wheel feels. If it is slow to respond or has become stiff, this is a likely sign that the pump is failing. When you need a new power steering pump, be sure the part you get is OEM so it fits your car.
