AUTOBODY 84C PRACTICE
EXAM COMPLETE
Question 1: Before making a structural pull on a unibody vehicle, what should the technician do �rst?
Choices:
1) Remove all exterior paint 2) Measure the vehicle and compare it with repair speci�cations 3) Heat the damaged rail 4) Cut away the damaged section Correct Answer: Measure the vehicle and compare it with repair speci�cations Explanation: Structural repair should begin with accurate measuring so the technician can identify the direction and amount of misalignment before pulling.Page 1
Question 2: What is the primary purpose of anchoring a vehicle to a frame machine before pulling?
Choices:
1) To improve paint adhesion 2) To keep the vehicle from moving while corrective force is applied 3) To prevent battery discharge 4) To soften high-strength steel Correct Answer: To keep the vehicle from moving while corrective force is applied Explanation: Anchoring holds the vehicle securely so pulling force moves the damaged structure rather than the entire vehicle.Question 3: When correcting collision damage, pulling force is generally applied in which direction?
Choices:
1) In the same direction as the impact 2) Opposite the direction that caused the damage 3) Straight downward only 4) Toward the nearest suspension point
Correct Answer: Opposite the direction that caused the damage
Explanation: Damage is usually corrected by reversing the forces that created it, using controlled pulls based on measurements.Page 2
Question 4: A technician is considering heating a high-strength steel rail to make it easier to straighten. What is the best practice?
Choices:
1) Heat it red hot before pulling 2) Use heat only if the vehicle maker's repair procedure speci�cally permits it 3) Heat only the outside surface 4) Always heat high-strength steel below the roo�ine Correct Answer: Use heat only if the vehicle maker's repair procedure speci�cally permits it Explanation: Many high-strength and ultra-high-strength steels can lose strength when heated.OEM repair information must determine whether heat is allowed.
Question 5: What reference is most important when determining whether a
damaged structural component may be sectioned?
Choices:
1) The paint manufacturer's color manual 2) The vehicle manufacturer's collision repair procedure 3) The tire sidewall label 4) The shop's labor-rate guide only
Correct Answer: The vehicle manufacturer's collision repair procedure
Explanation: Sectioning locations and methods depend on vehicle design. OEM collision repair procedures identify whether sectioning is allowed and where.Page 3
