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 - ✔✔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 - ✔✔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 - ✔✔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 - ✔✔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 - ✔✔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 - ✔✔B. a bent idler arm
A bent idler arm is the least likely problem. All the other choices could cause a
caster problem.
