ASE A4 practice test Questions and
Answers (100% Pass)
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 - Answer✔️✔️-C. Both Techs are right. Too much
runout or static out of balance in the front wheels will cause a
vibration
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
