Questions With Correct Answers
A vehicle is brought in with a bent subframe. Technician A says to section the
| | | | | | | | | | | | | | |
subframe. Technician B says the subframe should not be repaired and must be
| | | | | | | | | | | | |
replaced. Who is right? | | |
| A, B, Both, or Neither - CORRECT ANSWER✔✔-Technician B only
| | | | | | | | |
The subframe should never be sectioned, and should rarely, if ever, be worked. It
| | | | | | | | | | | | | |
is typically a bolt-on part that does not lend itself to traditional straightening
| | | | | | | | | | | | |
methods. Vehicle manufacturers recommend replacement.

The first step in bleeding brakes is to:
| | | | | | |
|
A. check the parking brake adjustment
| | | | |
B. check the master cylinder fluid level
| | | | | |
C. start the engine and pump the brakes
| | | | | | |
D. start the wheel farthest from the master cylinder - CORRECT ANSWER✔✔-B.
| | | | | | | | | | | |
check the master cylinder fluid level
| | | | |
The fluid level will have to be monitored as it is removed during the process, so
| | | | | | | | | | | | | | | |
always start with a full reservoir. Bleeding the farthest wheel first is good practice,
| | | | | | | | | | | | |
but not the first thing to do.

,Technician A says that negative camber is the tilt of the tire toward the front of
| | | | | | | | | | | | | | | |
the vehicle. Technician B says that negative camber means that the top of the tire
| | | | | | | | | | | | | |
is tipped in toward the centerline of the vehicle. Who is right?
| | | | | | | | | | | |
| A, B, Both, or Neither - CORRECT ANSWER✔✔-Technician B only
| | | | | | | | |
Camber is the inward or outward tip of the tire, as seen from the front of the
| | | | | | | | | | | | | | | | |
vehicle. When a wheel sustains an impact from the side, the camber is frequently
| | | | | | | | | | | | |
affected.

During A/C refrigerant recovery, 1 oz of oil has been recovered from the system.
| | | | | | | | | | | | | |
Which of these is the correct procedure?
| | | | | |
A. return the oil to the system
| | | | | |
B. replace the oil with new oil
| | | | | |
C. ignore such a small amount of new oil
| | | | | | | |
D. change all the oil in the system - CORRECT ANSWER✔✔-B. replace the oil with
| | | | | | | | | | | | | | |
new oil |
New oil should be used to restore the proper amount. Also replace additional
| | | | | | | | | | | | |
amounts for any components replaced. | | | |
A vehicle has positive caster on the right front wheel and zero caster on the front
| | | | | | | | | | | | | | | |
left wheel. Technician A says this will cause the vehicle to pull left. Technician B
| | | | | | | | | | | | | | |
says the vehicle will pull to the right. Who is right?
| | | | | | | | | |
, | A, B, Both, or Neither - CORRECT ANSWER✔✔-A. Technician A only
| | | | | | | | | |
The vehicle will always pull to the side with the least amount of positive caster, or
| | | | | | | | | | | | | | |
the greatest amount of negative caster.
| | | | | |
Caster on one side of a unibody vehicle is out of specification. The LEAST likely
| | | | | | | | | | | | | | |
cause is: |
A. a misaligned crossmember
| | |
B. a bent idler arm
| | | |
C. a damaged lower control arm
| | | | | |
D. a damaged strut rod - CORRECT ANSWER✔✔-B. a bent idler arm
| | | | | | | | | | |
A bent idler arm is the least likely problem. All the other choices could cause a
| | | | | | | | | | | | | | | |
caster problem. |
After repairing a vehicle, it is found that camber is out of spec on one side of the
| | | | | | | | | | | | | | | | | |
vehicle. Technician A says that there might be suspension mounting locations out
| | | | | | | | | | | |
of spec. Technician B says that before adjusting camber, SAI and included angle
| | | | | | | | | | | | |
should be checked and compared side-to-side. Who is right?
| | | | | | | |
| A, B, Both, or Neither - CORRECT ANSWER✔✔-Both Technician A and B.
| | | | | | | | | | |
A number of conditions can cause a camber reading to be off, such as damaged
| | | | | | | | | | | | | | |
parts or a distorted suspension mounting location. A visual examination of the
| | | | | | | | | | | |
parts is all that's needed in cases of severe damage. However, the only way to be
