Red Seal Transport Trailer Technician Practice Exam

To determine if a trailer's axle is bent, a technician should conduct a visual inspection or use alignment equipment. This approach allows for a thorough examination of the axle and its alignment with the trailer's frame. A visual inspection can reveal noticeable deformities or irregularities in the axle structure, while alignment equipment can measure the angles of the axle relative to the trailer, ensuring that everything is within specified tolerances.

Using alignment tools can provide precise measurements, helping to identify misalignments that may not be visible to the naked eye. These tools can highlight how the axle sits relative to the wheels and the frame, making it easier to diagnose any issues caused by bending or misalignment.

Other methods, such as measuring axle temperature or testing braking performance, are not direct indicators of whether the axle is bent. Temperature measurement may reveal issues related to bearing or brake problems but does not assess the physical shape of the axle. Similarly, evaluating braking performance is more about the functionality of the braking system rather than the structural integrity of the axle itself. Checking tire pressure is relevant to tire health and safety but doesn't provide insights into the condition of the axle. Therefore, conducting a visual inspection or using alignment equipment is the most effective method for identifying a bent axle.
