Question: 1 / 400

What visual indicators suggest wheel bearing issues on a trailer?

Excessive noise and feeling of heaviness

Low tire pressure and rust

Abnormal wheel play, grease leaking, or excessive heat

The presence of abnormal wheel play, grease leaking, or excessive heat are clear visual indicators that suggest potential issues with wheel bearings on a trailer. When wheel bearings begin to fail, they can cause noticeable movement when the wheel is manually tested for play, indicating that the bearings are not properly supporting the wheel.

Additionally, grease leaking from the wheel hub suggests that the seals may be compromised, allowing lubricant to escape and increasing the risk of overheating. If wheel bearings are overheating, it not only indicates a lubrication issue but can also lead to additional damage, with the potential to affect the performance and safety of the trailer. Recognizing these signs early can aid in performing timely maintenance or repairs, ensuring safe operation of the vehicle.

The other choices do not specifically highlight the direct visual indicators related to wheel bearing problems, making this the most relevant and accurate answer.
