An idler arm<\/a> supports one end of the steering center link and lets it pivot freely, keeping the linkage level so that your vehicle’s front wheels point where you steer. It bolts to the frame on the passenger side and mirrors the pitman arm on the driver side. Together, the two hold the center link at the right height and let it slide left and right as you turn the wheel. When the idler arm is healthy, your steering feels tight and precise. When it wears out, the front end gets loose, wanders, and can chew through tires.<\/p>\n\n\n\n
