Q1When preparing to repair a vehicle with significant frame damage, what is the FIRST step a technician should perform?
✓ Correct answer: D. Inspect and document all visible damage
Before beginning any frame repair, a proper inspection and documentation of all damage is critical. This helps identify the extent of damage, plan the repair sequence, and provides necessary documentation for insurance and quality control purposes.
Q2What type of frame damage is characterized by the frame rails being closer together at one end than the other when viewed from above?
✓ Correct answer: C. Diamond
Diamond damage is characterized by the frame rails being closer together at one end than the other when viewed from above, forming a diamond or parallelogram shape rather than a rectangle.
Q3Technician A says that a tram gauge can be used to check for sidesway damage. Technician B says that a tram gauge can be used to check for sag damage. Who is correct?
✓ Correct answer: B. Technician A only
A tram gauge can identify sidesway by measuring diagonal measurements from side to side, but cannot effectively measure vertical sag damage, which requires height measurements.
Q4When using a three-dimensional measuring system on a vehicle with frame damage, what is most important to ensure before taking measurements?
✓ Correct answer: A. The vehicle is properly leveled and anchored
The vehicle must be properly leveled and securely anchored before taking measurements with a three-dimensional measuring system to ensure accurate readings and comparisons to specification data.
Q5A vehicle with frame damage shows uneven gaps at the hood and fenders after a collision. The measuring system indicates that one frame rail is higher than the other. This condition is known as:
✓ Correct answer: D. Twist
When one frame rail is higher than the other, creating uneven gaps at the hood and fenders, this indicates twist damage where the frame has rotated around its longitudinal axis.
Q6After repairing a severely damaged frame rail, what should be done to protect against future corrosion?
✓ Correct answer: C. Apply appropriate primers, sealers, and anti-corrosion compounds
After frame repair, it's essential to restore corrosion protection by applying appropriate primers, sealers, and anti-corrosion compounds to protect the repaired areas from future rust and corrosion.
Q7When planning a repair sequence for a vehicle with multiple areas of frame damage, what should be addressed FIRST?
✓ Correct answer: B. Major structural misalignment
Major structural damage should be addressed first in the repair sequence as it establishes the base alignment for all subsequent repairs and ensures proper restoration of the vehicle's structure.
Q8What condition exists when a vehicle's frame rail is compressed from the front, causing it to be shorter than specification?
✓ Correct answer: A. Mash
Mash damage occurs when a frame rail is compressed from a collision, resulting in the rail being shorter than specification due to the compression force.
Q9During frame repair, stress-relieving procedures are performed to:
✓ Correct answer: D. Prevent distortion due to stored energy in the metal
Stress-relieving procedures are performed during frame repair to prevent distortion that could occur when the metal attempts to return to its original shape due to the stored energy from the collision.
Q10Technician A says that kickup damage can be identified by measuring a point on the frame that is higher than specification. Technician B says that sag damage can be identified by measuring a point on the frame that is lower than specification. Who is correct?
✓ Correct answer: C. Both Technician A and Technician B
Both technicians are correct. Kickup damage is identified when a point on the frame is higher than specification, while sag damage is identified when a point is lower than specification.
