What tool is used to check for hidden frame damage?

• A. Frame measuring system
• B. Ultrasonic thickness gauge
• C. Torque wrench
• D. Scribe gauge

Answer: (A)

Detecting hidden frame damage relies on measuring the vehicle’s structure against factory specifications. A frame measuring system is built for this task. It uses a reference frame or measuring platform and targets or sensors placed at specific points on the car. By capturing precise coordinates and comparing them to the manufacturer’s tolerance values, the system reveals any deviations in the frame geometry. This shows if the chassis is bent or out of alignment even when surface panels look fine, guiding the technician on whether straightening or further structural repair is needed. Other tools have different purposes: an ultrasonic thickness gauge checks how thick a metal panel is, not the frame’s alignment; a torque wrench is for tightening fasteners to a specified torque; a scribe gauge helps measure panel gaps, but it doesn’t assess frame straightness.
