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 sta c 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
C. Both Techs are right. Too much runout or sta c out of balance in the front wheels will cause a
vibra on
3. A vehicle has front wheel shimmy at low speed and requires increased steering effort. Tech A
says that too much posi ve camber could be the cause. Tech B says that too much Posi ve
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
B. Excessive posi ve caster will increase steering effort, cause the steering wheel to return too
rapidly. cause wander at high speed and shimmy at low speed.
4. All of these could cause re wear if not within manufacturer's Specs EXCEPT:
A. Caster
B. Wheel balance
C. Toe-In
D. Camber
A. Caster that is out of spec will affect steering and handling characteris cs, but will not cause
re wear. Whereas, too much toe in or out would severely wear the res. Addi onally, excessive
camber would cause inside or outside shoulder wear on the re, depending on whether the
camber was too nega ve or posi ve.
5. A vehicle with variable assist power steering has a lack of power assist in both direc ons.
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
B. Although further diagnosis will be necessary, Tech B is right. Tech A is wrong because, when
there is a malfunc on in a variable assist power steering system, the system will allow full
power steering.
6. A customer complains that a vehicle wanders on a bumpy road and needs con nual driver
correc on to stay straight. What could be Wrong?
A. Excessive nega ve front caster
B. Insufficient front toe
C. Rear or front bump steer
D. All of the above
D. Excessive nega ve caster, insufficient front toe, and front or rear bump steer could cause a
vehicle to wander on a bumpy road.
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 le: 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 e-rod
D. Both B and C
D. either a bent pitman arm or a e rod could cause the specifica ons 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.
8. When checking a re, a tech find it to have too much radial (up and down) runout. Tech A
says to rotate the re and wheel assembly on the moun ng studs to correct the problem. Tech
B says to rotate the re on the wheel assembly to a?empt to bring the runout within specs.
Who is right?
A. Tech A Only
B. Tech B Only
C. Both A and B
C. Neither
, B. Rota ng the re on the wheel will compensate for wheel/ re differen al (posi oning the
highest spot on the re at the lowest spot on the wheel.) Whereas', rota ng the wheel
assembly on the moun ng studs will have no effect on runout.
9. If you readjust camber on the le: front strut, which, if any, of these specs might change
A. Right caster
B. Le: toe and total toe
C. SAI
D. None of the above.
B. Readjus ng camber will have an affect on the individual toe for the le: wheel as well as the
total toe. SAI is not adjustable and generally, caster is not adjustable either on a strut
suspension.
10. Too much caster on the le: front wheel will cause the __________
A. vehicle to dri: to the le:
B. Le: re to wear on the outside edge
C. vehicle to dri: to the right
D. le: re to wear on the inside edge.
C. A vehicle will tend to steer or dri: to the side with the least amount of caster. Caster will not
cause re wear, but excessive camber will cause wear to the inside of outside shoulders of a
re.
12. A pressure test is being performed on a car with power steering. The pressure readings
taken when the wheels are at the right and le: stops are below specs. The tester readings are
normal when the tester shutoff valve is closed. tech A says that these readings could be caused
by a bad steering gear. tech B says that a bad pump could cause these readings. Who is right?
A. Tech A Only
B. Tech B Only
C. Both A and B
D. neither
A. A bad steering gear would cause the readings to be low when the steering is at the right and
le: stops, but the readings would be normal with the tester shutoff valve closed.
13. a vehicle with a manual rack and pinion steering gear has a shimmy. Tech A says that worn
rack to frame moun ng bushings could be the cause. tech B says that loose inner or outer e
rod ends (sockets) could be the cause. Who is right?
