Steering wheel shudders while turning, what could be the cause? (Vibrating) A.) air in power steering fluid B.) loose power steering belt - answerBoth= air in power steering fluid would cause cavitation and loss of hydraulic assistance / a slipping and grabbing effect of a loose power steering belt would cause this symptom as well. removing the pitman arm change will not change alignment setting.
