• Inspect or have your idler and pitman arms inspected for signs of wear. Exposure to dirt, road salt, and other harsh road conditions can cause wear and tear on your steering arms, or cause connections to loosen. One way to test your steering arm assemblies is to try to turn the steering wheel while your vehicle is parked. If you can turn the steering wheel a significant amount without resistance, then you may have a worn idler or pitman arm.


• Replace your vehicle’s idler and pitman arms at the same time. Since the idler arms and pitman arms are exposed to similar wear conditions, you should replace the steering arms at the same time. After your new arms are installed, have a professional alignment done.
