Which of the following can indicate a worn-out steady bearing?

The presence of a clunking noise during gear engagement is indeed indicative of a worn-out steady bearing. Steady bearings are designed to support the drivetrain, maintaining alignment and reducing vibrations during operation. When these bearings begin to wear, they can lose their ability to effectively support the components, leading to irregular movement and resultant noise during gear engagement.

The clunking sound occurs due to the increased play or looseness in the bearing, which can cause misalignment and a jarring effect as gears engage. This unwanted movement manifests as a clunk noise, signaling that the steady bearing may require inspection or replacement.

While other symptoms could suggest issues with various vehicle components, they do not specifically point to the condition of the steady bearing. For instance, engine stalling may arise from fuel system issues or ignition problems, increased engine vibrations could suggest imbalance or misfiring, and difficulty in steering is more associated with steering components rather than drivetrain issues. Thus, the clunking noise serves as a direct indicator of a problem with the steady bearing itself.
