The Pitman Arm,also known as the "steering arm," is the main player while the idler arm supports the other side and allows the proper movement to take place when you turn the wheel. If your steering has gotten sloppy they may need replacement.Now comes the fun part. Separating the idler arm and the center link can be a real pain.
