What indicates a defect in leaf springs?

A defect in leaf springs can be indicated when they are shifted or out of place. Leaf springs are critical components of a vehicle’s suspension system, designed to support the weight of the vehicle and absorb shock from the road. When they are misaligned or not in their proper position, it can lead to improper handling, an uneven distribution of weight, and potential failure of the suspension system, which could compromise safety.

The other options do not suggest a defect. For instance, leaf springs that are securely mounted are functioning as intended, while those described as new or in above-average condition are most likely effective and reliable. It's essential to assess the positioning and secure fastening of the springs to ensure they are adequately performing their role in the vehicle's suspension system.
