Question 1
2. A driver says that the front end of his car vibrates up and down while traveling at most
road speeds. Tech A says that too much runout of the front wheels could be the cause.
Tech B says that a static out of balance of the front wheels could be the cause. Who is
right?
A. Tech A only
B. Tech B only
C. Both A and B
D. Neither A or B
CORRECT ANSWER
C. Both Techs are right. Too much runout or static out of balance in the front wheels will
cause a vibration
Question 2
3. A vehicle has front wheel shimmy at low speed and requires increased steering effort.
Tech A says that too much positive camber could be the cause. Tech B says that too much
Positive caster could be the cause. Who is right?
A Tech A only
B. Tech B only
C. Both A and B
D. Neither A or B
CORRECT ANSWER
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.

,Question 3
4. All of these could cause tire wear if not within manufacturer's Specs EXCEPT:
A. Caster
B. Wheel balance
C. Toe-In
D. Camber
CORRECT ANSWER
A. Caster that is out of spec will affect steering and handling characteristics, but will not
cause tire wear. Whereas, too much toe in or 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.
Question 4
5. A vehicle with variable assist power steering has a lack of power assist in both
directions. Tech A says That the problem is in the electronic control system. Tech B says
that there could be a problem in the steering gear or a bad power steering pump. Who is
right?
A. Tech A only
B. Tech B only
C. Both A and B
D. Neither A or B
CORRECT ANSWER
B. Although further diagnosis will be necessary, Tech B is right. Tech A is wrong because,
when there is a malfunction in a variable assist power steering system, the system will
allow full power steering.

,Question 5
6. 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
CORRECT ANSWER
D. Excessive negative caster, insufficient front toe, and front or rear bump steer could
cause a vehicle to wander on a bumpy road.
Question 6
7. While aligning a front end, a technician finds the toe out on turns (turning Radius) to be
greater than the manufacturer's Specs and it has 2.0 degrees difference from the 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
CORRECT ANSWER
D. either a bent pitman arm or a tie rod could cause the specifications for the toe out on
turns to be out of spec. Vehilces with non symmetrical steering systems will have a
difference from side to side, but the difference will not exceed the manufacturer's specs
and it rarely has a greater than 1.5 degrees difference from side to side.
Question 7
8. When checking a tire, a tech find it to have too much radial (up and down) runout. Tech
A says to rotate the tire and wheel assembly on the mounting studs to correct the

, problem. Tech B says to rotate the tire on the wheel assembly to attempt to bring the
runout within specs. Who is right?
A. Tech A Only
B. Tech B Only
C. Both A and B
C. Neither
CORRECT ANSWER
B. Rotating the tire on the wheel will compensate for wheel/tire differential (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.
Question 8
9. If you readjust camber on the left front strut, which, if any, of these specs might change
A. Right caster
B. Left toe and total toe
C. SAI
D. None of the above.
CORRECT ANSWER
B. Readjusting camber will have an affect 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.
Question 9
10. Too much caster on the left front wheel will cause the __________
A. vehicle to drift to the left
B. Left tire to wear on the outside edge
C. vehicle to drift to the right
