B4: Study Questions
1. Which of the following components is the LEAST-Likely to be damaged in a severe rear
impact (A. quarter panel, B. rear bumper, C. center pillar, D. fender)? - ANS-Fender.
2. All of the following can be used to remove a windshield EXCEPT (A. fine knife, b. Diano wire,
C. pneumatic knife, D. hammer)? - ANS-Hammer. Pneumatic knife, fine.
3. What determines the welding process used to make the repair (A. manufacturer's
recommendations, B. shop procedures, C. tools available, D. technician's welding experience)?
- ANS-Manufacturer's recommendations.
4. Technician A says that damaged side rails can be replaced. Technician B says that damaged
cross members can be replaced. Who is right? - ANS-Both A and B
5. What type of damage is present if a vehicle's centerline is not within specifications (A. mash,
B. sag, C. sidesway, D. kickup)? - ANS-Sidesway. Sidesway changes the alignment to the
center of a damaged vehicle. A mash changes the length of a vehicle; sag and kickup change
the height of a vehicle.
6. Technician A uses water to cool metal that has been heated during a repair. Technician B
says to let the metal cool naturally. Who is correct? - ANS-B only. The use of water to cool the
hot metal could lead to fatigue problems.
7. What type or damage is found in the vehicles center section only (A. sag, B. twist, c. kickup,
D. mash)? - ANS-Twist. Twist damage is corrected by pulling down on high corners of the center
section and pushing up on the low corners of the center section.
8. How far should an insert extend, in either direction, from a crack in a frame rail (A. 2 inches,
B. 4 inches, C. 6 inches, D. 8 inches)? - ANS-6 inches. Manufacturer's specifications should be
followed when inserts are used for frame repairs. The specifications from some manufacturers
are 6 inches in each direction for such a repair.
9. Which of the following is the best tool to use to remove modular glass without damage? (A.
pneumatic knife, B. fine knife, C. piano wire, D. hammer)? - ANS-pneumatic knife. On modular
glass, the molding is attached to the glass. To safely remove the glass without destroying the
moldings, use a pneumatic knife with a narrow blade to cut through the urethane seal that is
holding the glass in place.
10. In Which of the following measuring devices is the best to check for misalignment of the
spring towers (A. tram gauge, B. self-centering gauges, C. strut tower gauge, D. tape
measure)? - ANS-strut tower gauge.
, 11.I Which of the following types of frame damage is identified with a tram gauge (A. sag, B.
diamond, C. twist, D. kickup)? - ANS-Diamond. Sag, twist, and kickup damage are diagnosed
using gauges. Diamond damage is measured using a tram gauge. Refer to the manufacturer's
reference manuals when taking measurements. Diamond condition can be diagnosed by cross-
or X-checking on the frame members.
12. The process of welding two edges of adjacent panels together, it is called a (A. lap weld, B.
flange weld, C. plug weld, D. butt weld)? - ANS-Butt Weld. Butt welds are performed by welding
the edges of two adjacent panels.
13. Which type of damage is usually corrected first (A. sag, B. kickup, C. mash, D. sidesway)? -
ANS-Mash. This involves the length of the vehicle. To correct a mash condition, pulls would be
made by pulling in the opposite direction of the condition. Stress-relieving will help realign the
metal's molecules to their normal relaxed condition while making pulls.
14. Technician A says weld-bond panels help reduce noise and vibration. Technician B says tied
bonding adhesives can be applied over weld-through primers. Who is right? - ANS-A only.
Bonding adhesives should never be applied over weld-through primers as that would
compromise the weld-bond seam by causing the adhesive to fail.
15. Alof the flowing can be used to diagnose possible causes of steering problems EXCEPT (A.
make sure vehicle is on level surface, B. check tire and wheel runout, C. perform a jounce test,
D. steering wheel diameter)? Steering wheel diameter. Checking a vehicle on a level surface,
tire and wheel runout, and jounce tests can be used to diagnose vehicle steering problems. -
ANS-
16. In what position is it best to keep welding voltage low and weld arc as short as possible (A.
overhead, B. vertical, C. horizontal, D. flat)? - ANS-Overhead. To perform this weld the MIG
welder must be set up to keep the voltage low and the weld arc short. You will need to keep the
weld puddle small and the welding nozzle in contact with the metal when performing overhead
welds.
17. Technician A says that all corrosion protection materials must be applied after welding.
Technician B says anticorrosion compounds can be wax- or petroleum-based. Who is right? -
ANS-B only. Some corrosion protection materials, such as seam sealers and conversion
coatings, are applied after welding. However, weld-through primers must be applied prior to
welding.
18. When pulling high on the vehicle to prevent distortion to the roof, it is also necessary to (A.
pull high on the other side, B. tie down the opposite side, C. tie down the same side, D. tie down
the vehicle ends)? - ANS-tie down the opposite side. This will help keep the upper
measurements in line when making pulls to correct damage on the opposite side.
1. Which of the following components is the LEAST-Likely to be damaged in a severe rear
impact (A. quarter panel, B. rear bumper, C. center pillar, D. fender)? - ANS-Fender.
