ANSWERS { GRADED A+}
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 - (ANSWERS)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 - (ANSWERS)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 - (ANSWERS)Technician B only
Camber is the inward or outward tip of the tire, as seen from the front of the vehicl

ANSWERS { GRADED A+}
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 - (ANSWERS)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 le
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 - (ANSWERS)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 - (ANSWERS)B. A bent idler arm

ANSWERS { GRADED A+}
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 o
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 - (ANSWERS)Both Technician A and B.
A number of conditions can cause a camber reading to be off, such as damaged par
or a distorted suspension mounting location. A visual examination of the parts is al
that's needed in cases of severe damage. However, the only way to be sure is to
check both SAI and included angle readings to determine where the damage is.
A driver's side airbag was cut during a collision but did not deploy. What is the
proper action?
A. Use plastic repair adhesive to repair the cut and refinish the bag
B. Return the bag to the manufacturer for recycling
C. Replace the bag with an OEM part, deploy the old bag before disposal
D. Replace with a salvage part - (ANSWERS)C. Replace the bag with an OEM par
deploy the old bag before disposal
Only OEM parts should be used. Any damage to an airbag module requires
replacement.
A repaired vehicle is found to have an SAI difference where one side is within spec
