An idler arm is a steering component in vehicles with parallelogram steering, i.e. those that use a center link. An idler arm assembly is not present in vehicles that use rack and pinion steering.The idler arm works in concert with the pitman arm to allow the center link to move and in turn move the tie rods and steer the wheels of the vehicle. The pitman arm is turned by the steering box and moves the center link left and right.The idler arm keeps the center link tracking correctly on the other side and keeps it parallel to the road. For this reason, the idler arm is bolted to the frame on the passenger side.It attaches to a hole in the center link via a ball joint or a tapered end.he pitman arm is turned by the steering box and moves the center link left and right. The idler arm keeps the center link tracking correctly on the other side and keeps it parallel to the road. For this reason, the idler arm is bolted to the frame on the passenger side.
