How to Remove a Pitman Arm

On a recirculating ball steering system, the steering box connects to the steering linkage via a splined shaft that holds the pitman arm. Over time, the splines on the pitman arm can wear out, as can the connection to the linkage, which makes the steering sloppy and unpredictable. The process of replacing the pitman arm requires a pitman arm pulling tool, but otherwise can be done at home with basic tools.

Things You'll Need

• Jack
• Jack stands
• Pliers
• Open-end wrench set
• 1/2-inch ratchet, extension and socket set
• Pitman arm puller

Instructions

1. Lift up the front of the vehicle using the jack and secure it on jack stands. Make sure the vehicle is completely secure on the jack stands before you crawl underneath it.

2. Unbolt the steering linkage from the pitman rod using a pair of pliers to flatten out the cotter pin and an open-end wrench to unbolt the castle nut from the steering linkage. Pull the linkage out of the arm with your hands so that its out of the way.

3. Unbolt the pitman arm from the steering box using the 1/2-inch ratchet, extension and socket. Once it's unbolted, place the pitman arm puller on the pitman arm. This tool is shaped like a "U" and has a threaded bolt in the middle place the bolt on the splined end of the steering box, with the U shape going around the pitman arm. Tighten down the bolt in the center, using the 1/2-inch ratchet, extension and socket. This will pull the pitman arm off of the splined shaft and release it from the vehicle.
