There is an important part in the power steering system named power steering reservoir. The power steering system makes sure the car stays stable when it's off, and makes it possible when you do truing and all the wheels and tires need to change the direction. It's all about the power steering system, and the system is consisted of power steering pump, belt, hoses and steering gear. When the power steering reservoir is low, the steering will get tough to manipulate. Here are some signs showing that the power steering reservoir in your car is failing: if you find turning the steering wheel is difficult; if the power steering fluid is leaking; if there is some groaning-like noise when you turn the steering wheel, you need to stop driving immediately and check it if the replacement is necessary. Once you decide to change, we are glad to offer you all Subaru genuine OEM power steering reservoir with a discounted price.
