Idler and pitman need to move together so tires move together

Tahiko idler arm holds the right side of the steering linkage. Its function is to mirror the movement of the pitman arm which holds the left side of the linkage (pitman arm is attached to the steering gear. i.e. when you turn the steering wheel, the steering gear turns the pitman arm which moves the steering linkage to turn the tires.). Idler and pitman need to move together so tires move together.
