An idle arm can vibrate due to several factors, including an imbalance in the engine's idle speed, misfiring cylinders, or worn engine mounts that fail to dampen vibrations. Additionally, issues with the idle air control valve or vacuum leaks can cause irregular airflow, leading to unstable engine performance. External factors such as road vibrations or unbalanced accessories (like the alternator or Power Steering pump) can also contribute to the vibration.
Simply replace them. Make sure the pitman arm is bad before replacing it.

There is more than likely a problem with the idle arm censor that would cause this. There may also be a problem with the throttle body.
You will need a special tool called a "fork" that pops the connection. Remove the nut at the end of the idle arm joint then put the fork in place and give it a few good hits with a big hammer. Of course you will complete the destruction of the idle arm, but you're replacing it anyway. After the joint is loose, remove the bolts from the frame and drop the idle arm and replace it.

To replace an idle arm, first, ensure the vehicle is safely lifted and supported on jack stands. Remove any necessary components that obstruct access, such as the wheel or suspension parts. Unbolt the old idle arm from its mounting points, then install the new idle arm in reverse order, ensuring all fasteners are tightened to the manufacturer's specifications. Finally, align and check the vehicle's steering and suspension for proper function before taking it for a test drive.
