Without a fully-operational power steering system, you can't effectively control your vehicle. Severe steering wheel vibrations are signs that the belt is defective, wobbly or needs to be changed. Another symptom of faulty steering occurs when your wheels and tires are hard to turn. This usually happens because there is damage to the power steering belt, low levels of power steering fluid or a seepage in the power steering rack. You should also pay attention to howling or whining sounds coming from the steering wheel after turns, which indicates the power steering fluid is low. XN Machinery's selection of power steering pumps enables you to turn your wheel comfortably, without feeling shaking or heaviness, or hearing noises.
