What is the Pitman Arm Shaft Seal all about?

In order to transmit direction from the steering wheel to the vehicle’s wheels and tires, a complex network of interconnected components is used. The steering wheel connects to two different steering shafts, which connect to the gearbox. The pitman arm connects to the other side of the gearbox, and is responsible for helping to move the wheel in the desired direction.

The pitman arm shaft seal essentially serves the same purpose as the steering shaft seal – it prevents power steering fluid from exiting the gearbox. It is protected by a dust cover, which helps to ensure that dirt and dust don’t compromise the interior seal. Both are held in place by snap rings.

Replacing a pitman arm shaft seal is a little simpler than replacing a steering shaft input seal, and it can be done without removing the gearbox. With that being said, the pitman arm does need to be disconnected and moved out of the way, and there is a significant amount of teardown needed. Have one of our expert mechanics replace the pitman arm shaft seal if required.
