What Does a Pitman Arm Do?

The pitman arm is a crucial component of the steering system in a vehicle. It connects the steering box to the center link, which is responsible for transmitting the motion from the steering wheel to the wheels of the vehicle. The pitman arm acts as a linkage between the steering box and the center link, allowing the driver to control the direction of the vehicle. Without a properly functioning pitman arm, steering would be nearly impossible, posing a significant risk to the driver and passengers.

The pitman arm is typically a solid, stout metal arm with a ball joint at one end and a tapered hole at the other. It is attached to the steering box output shaft through the ball joint and to the center link through the tapered hole. As the driver turns the steering wheel, the motion is transferred to the pitman arm, causing it to rotate. This rotation then moves the center link, which ultimately turns the wheels in the desired direction.

Given its critical role in the steering system, it is essential for the pitman arm to be in good condition. Over time, however, the pitman arm can wear out or become damaged due to various factors, such as regular wear and tear, exposure to harsh road conditions, or improper maintenance. When this happens, it can significantly affect the vehicle’s steering performance and compromise safety.
