ASE A4 - Suspension & Steering Exam
Questions With Correct Answers
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 - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT 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
| | | | | |
D. Left tire to wear on the inside edge - CORRECT ANSWER✔✔-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

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✔✔-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.

C. Right SAI
| |
D. None of the above - CORRECT ANSWER✔✔-The correct answer is B.

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 - CORRECT ANSWER✔✔-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
