What is the correct inspection procedure for an idler arm?

The correct procedure for inspecting an idler arm involves applying hand pressure to check for movement. This method is effective because it allows the technician to feel for any excessive play or looseness in the idler arm while the vehicle is in its normal operating position, with the wheels on the ground. By keeping the wheels on the ground, the suspension and steering components are under their normal load, which provides a more accurate assessment of wear or damage.

Inspecting the idler arm in this way allows the technician to determine if it is functioning properly and if there are any significant issues that could affect the steering system's performance. This approach prioritizes safety and ensures that the idler arm is evaluated under realistic conditions as it would perform during driving.
