What are the typical signs of structural integrity issues?

The presence of cracks, bends, or unusual noises when driving are definitive indicators of potential structural integrity issues in a vehicle. When the structure of a vehicle is compromised, it can manifest as visible defects like cracks or bends in the frame or body panels. These signs suggest that the vehicle's ability to withstand stresses is impaired, which can affect safety and performance.

Additionally, unusual noises may arise from components that have been damaged or misaligned due to structural issues. These sounds can be emanating from areas where the structure has deformed or where parts are no longer fitting together properly, indicating a need for closer inspection and potential repair.

In contrast, other options like enhanced fuel efficiency or increased vehicle weight generally do not correlate with structural integrity concerns. Lower tire pressure, while important for safety and functionality, does not directly indicate issues with the vehicle's structural integrity. Therefore, the signs of cracks, bends, and strange noises provide critical information regarding the health of the vehicle's structure and must be taken seriously to ensure safe operation.
