ACTUAL COMPLETE EXAM QUESTIONS AND CORRECT DETAILED
ANSWERS (VERIFIED ANSWERS ) ALREADY GRADED A+.
A driver says that the front end of his car vibrates up and down while
traveling at most road speeds. Technician A says that too much
runout of the front wheels could be the cause. Technician B says that
static out-of-balance of the front wheels could be the cause. Who is
right?
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A of B - ANSWER-The correct answer is C, both technicians
are right. Too much runout or static out-of-balance in the front
wheels will cause a vibration.
A vehicle has front wheel shimmy at low speed and requires
increased steering effort. Technician A says that too much positive
camber could be the cause. Technician B says that too much positive
caster could be the cause. Who is right?
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B - ANSWER-The correct answer is B. Excessive
positive caster will increase steering effort, cause the steering
wheel to return too rapidly, cause wander at high speed and
shimmy at low speed.
,All of these could cause tire wear if not within manufacturer's
specifications EXCEPT:
A. Caster
B. Wheel balance
C. Toe-in
D. Camber - ANSWER-The correct answer is A. Caster that is out of
specification will affect steering and handling characteristics, but
will not cause tire wear. Whereas, too much toe-in our out would
severely wear the tires. Additionally, excessive camber would
cause inside or outside shoulder wear on the tire, depending on
whether the camber was too negative or positive.
A vehicle with variable assist steering has a lack of power assit in
both directions. Technician A says that the problem is in the
electronic control system. Technician B says that there could be a
problem in the steering gear or a bad power steering pump. Who is
right?
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B - ANSWER-The correct answer is B. Although further
diagnosis will be necessary, technician B is right. Technician A is
wrong because, when there is a malfunction in a variable assist
power steering system, the system will allow full power steering.
,A customer complains that a vehicle wanders on a bumpy road and
needs continual driver correction to stay straight. What could be
wrong?
A. Excessive negative front caster
B. Insufficient front toe
C. Rear or front bump steer
D. All of the above - ANSWER-The correct answer is D. Excessive
negative caster, insufficient front toe, and front or rear bump steer
could cause a vehicle to wander on a bumpy road.
While aligning a front end, a technician finds the toe-out on turns
(turning radius) to be greater than the manufacturer's specifications
and it has 2.0 degrees difference front he left side to the right side.
Which, if any, of the following could be the cause?
A. Nothing is wrong; the vehicle has a non-symmetrical steering
design
B. Bent pitman arm
C. Bent tie-rod
D. Both B and C - ANSWER-The correct answer is D. Either a bent
pitman arm or a tie-rod could cause the specifications for toe-out
on turns to be out of specification. Vehicles with non-symmetrical
steering systems will have a difference from side-to-side, but the
difference will not exceed the manufacturer's specifications and it
rarely has greater than 1.5 degrees difference from side-to-side.
When checking a tire, a technician finds it to have too much radial (up
and down) runout. Technician A says to rotate the tire and wheel
, assembly on the mounting studs to correct the problem. Technician B
says to rotate the tire on the wheel assembly to attempt to bring the
runout within specifications. Who is right?
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B - ANSWER-The correct answer is B. Rotating the tire
on the wheel will compensate for wheel/tire differential (e.g.
positioning the highest spot on the tire at the lowest spot on the
wheel). Whereas, rotating the wheel assembly on the mounting studs
will have no effect on runout.
If you readjust camber on the left front strut, which, if any, of these
specifications might change?
A. Right caster
B. Left toe and total toe
C. Right SAI
D. None of the above - ANSWER-The correct answer is B. Readjusting
camber will have an effect on the individual toe for the left wheel as
well as the total toe. SAI is not adjustable and generally, caster is
not adjustable either on a strut suspension.
Too much caster on the left front wheel will cause the:
A. Vehicle to drive to the left
B. Left tire to wear on the outside edge
C. Vehicle to drive to the right
