C. Both A and B
D. Neither A of B - (ANSWERS)The correct answer is C, both technicians are righ
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 - (ANSWERS)The correct answer is B. Excessive positive caste
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 - (ANSWERS)The correct answer is A. Caster that is out of specificatio
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, dependin
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
says that there could be a problem in the steering gear or a bad power steering pum
Who is right?
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B - (ANSWERS)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 - (ANSWERS)The correct answer is D. Excessive negative

wander on a bumpy road.
While aligning a front end, a technician finds the toe-out on turns (turning radius) t
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 - (ANSWERS)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 differenc
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 - (ANSWERS)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 o

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 - (ANSWERS)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
D. Left tire to wear on the inside edge - (ANSWERS)The correct answer is C. A
vehicle will tend to steer or drift to the side with the least amount of caster. Caster
will not cause tire wear, but excessive camber will cause wear to the inside or
outside shoulders of a tire.
A pressure test is being performed on a car with power steering. The pressure
readings taken when the wheels are at the right and left stops are below
specifications. The tester readings are normal when the tester shutoff valve is close
Technician A says that these readings could be caused by a bad steering gear.
