ASE STEERING AND SUSPENSION
EXAM STUDY QUESTIONS AND
ANSWERS
The correct answer is B. Since the right side has too much negative camber,
this will cause the tire to tilt inwards at the top and cause the right tire to
wear the inside shoulder of the tire more quickly. It is also likely that the left
tire would wear on the outside shoulder due to too much positive camber. -
ANSWER-The above alignment settings would result in which of the following
conditions?
A. Left tire wear on the inside. vehicle does not pull to either side.
B. Right tire wear on the inside, vehicle pulls to the left
C. Right tire wear on the outside, vehicle pulls to the left.
D. Right tire wear on the outside. left tire wear on the inside and vehicle pulls
to the left.
The correct answer is C. Too much runout or static out-of-balance in the front
wheels will cause a vibration. - ANSWER-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 correct?
A. Technician A
B. Technician B
C. Both A and B
D. Neither A or B
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. - ANSWER-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 correct?
A. Technician A
B. Technician B
C. Both A and B
D. Neither A or B
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 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. - ANSWER-All of these
could cause tire wear if not within manufacturer's specs EXCEPT:
A. Caster
B. Wheel Balance
c. Toe-in
D. Camber
The correct answer is D. Caster is the lift of the top of the steering axis
toward the front (negative) or rear (positive) of the vehicle as viewed from
the side. Camber is the tilt of the top of the tire towards the inside (negative)
or outside (positive) of the vehicle as viewed from the front. - ANSWER-
Technician A says negative caster is the tilt of the tire towards the front of
the vehicle. Technician B says negative camber is the tilt of the tire toward
the rear of the vehicle. Who is correct?
A. Technician A
B. Technician B
C. Both A and B
D. Neither A or B
The correct answer is D. Excessive negative caster, insufficient front toe,
front or rear bump steer could cause a vehicle to wander on a bumpy road. -
ANSWER-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 of front bump steer
D. All of the above
The correct answer is D. Either a bent Pitman arm or a tie-rod could cause
the specification 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 manufacturer's specifications and it rarely
has greater than 1.5 degrees difference from side-to-side. - ANSWER-When
checking a tire, a technician finds it to have too much axial (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
and wheel assembly to attempt to bring the runout within specifications.
Who is correct?
A. Technician A
B. Technician B
C. Both A and B
D. Neither A or B
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. - ANSWER-While aligning a
front end, a technician finds the toe-out on turns (turning radius) to be
greater than manufacturer's spec 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
The correct answer is 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. -
ANSWER-If you readjust camber on the left front strut, which, if any, of these
specifications might change?
