●● 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
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.
●● 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
,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.
●● 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
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.
●● 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
,Answer: D. Excessive negative 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 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: 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.
●● 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
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.
●● 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.
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.
●● 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
D. left tire to wear on the inside edge.
