ASE T5 (2)
1. A device that is used on suspensions to primarily absorb energy and dampen
suspension oscillation is called:
A. An equalizer bracket.
B. A torque rod.
C. A spring.
D. A shock absorber. - ANS-Answer A is incorrect. An equalizer bracket is used to
mount and house the equalizer.
Answer B is incorrect. The torque arm is used to control axle rotational forces and to
maintain and adjust axle alignment.
Answer C is incorrect. The spring assemblies distribute the vehicle load across the
frame and provide a cushion between the road surface and the vehicle.
Answer D is correct. Shock absorbers dampen spring oscillation by limiting the effects of
spring jounce and rebound
2. Upon inspection, excessive play in the steering column assembly on a truck equipped
with a tilt steering column is noted. Which of the following would be the LEAST LIKELY
cause?
A. Loose lock shoe in the support
B. Faulty anti-lash spring in the centering sphere
C. Loose tilt head pivot pins
D. Column mounting bracket bolts loose - ANS-Answer A is incorrect. Tilt mechanisms
are designed to allow for the column to be adjusted and then held securely in that
position by the lock shoe mechanism. If the lock shoe pin and wedge lock components
are worn, excessive movement in the steering column would be the result.
Answer B is correct. A faulty anti-lash spring might cause the housing to be loose, but it
would not cause excessive play in the steering column assembly.
Answer C is incorrect. The main housing pivots on the pivot screws located on each
side of the main housing support bracket. If the pins become worn, the steering column
would have excessive movement because the pivot pins are not holding the column
securely in place.
Answer D is incorrect. The column mounting bolt bracket secures the column. If the
bracket bolts become loose, the column would shift and have movement in the steering
column assembly.
,4. While discussing steering system components, Technician A states that a typical
single-axle truck system has one Ackerman arm. Technician B says that the Ackerman
arm controls turning radius. Who is correct?
A only
B only
Both A and B
Neither A nor B - ANS-Answer A is incorrect. There are two Ackerman arms in the
steering system.
Answer B is correct. Only Technician B is correct. Ackerman arms control the turning
radius and allow for each front wheel to rotate on different arcs while turning.
Answer C is incorrect. Only Technician B is correct.
Answer D is incorrect. Technician B is correct.
5. A driver complains that after hitting a bump his vehicle suddenly veers to the right or
left. Which of these is the LEAST LIKELY cause?
A. A loose idler arm
B. A damaged relay rod
C. A worn tie rod end
D. A wheel out of balance - ANS-Answer A is incorrect. A loose idler arm will cause
fluctuation in the steering when striking a bump.
Answer B is incorrect. A damaged relay rod can cause veering when striking a bump
because of looseness in the ball joint end of the relay rod.
Answer C is incorrect. A worn tie rod end can cause veering when striking a bump
because of looseness in the ball joint end of the tie rod.
Answer D is correct. Wheel balance will not cause veering, only a shaking in the
steering wheel.
6. The alignment angle that is LEAST LIKBLY to cause the greatest tire wear is.
A. Castor.
B. Turning radius.
C. Toe-in.
D. Camber. - ANS-Answer A is correct. Castor is a non tire wearing angle. Excessive
Castor will be present with steerability complaints and wheel shimmy at low speeds.
Answer B is incorrect. Turning radius usually does not cause tire wear unless the
Ackerman arms are damaged or the wrong Ackerman arm is installed.
Answer C is incorrect. Toe in causes the greatest tire wear. Improper toe adjustment
causes rapid tire wear, which may result in tire failure, collision damage, and personal
injury. Excessive toe Out causes wear on the inside of the tire tread ribs and a sharp
feathered edge on the outside of the tread ribs. If excessive toe-in is present, the tire
tread wear is reverses
,Answer D is incorrect. Camber can cause tire wear but not as great a tire wearing angle
as toein
Technician A states that in order for a steerable suspension to steer or track correctly, it
is necessary for the front wheels to be in a toe-out condition. Technician B says that the
toe setting should be between 1/16 inch and 1/8 inch. Who is correct?
A only
B only
Both A and B
Neither A nor B - ANS-Answer A is incorrect. The front wheels need to be in a toe-in
condition.
Answer B is correct. Only Technician B is correct. The toe setting should be between
1/16 inch and 1/8 inch.
Answer C is incorrect. Only Technician B is correct.
Answer D is incorrect. Technician B is correct.
Alignment procedures are being discussed. Technician A says that installing the caster
shim between the axle and spring with the thick part to the rear will make the caster
angle positive Technician B says installing the caster shim between the axle and spring
with the low side at the front will make the caster angle more negative. Who is correct?
A only
B only
Both A and B
Neither A nor B - ANS-Answer A is correct. Only Technician A is correct. You make
caster more positive by installing a shim between the axle and spring with the high side
at the rear.
Answer B is incorrect. You make the caster more negative by installing a shim between
the axle and spring with the low side at the rear.
Answer C is incorrect. Only Technician A is correct.
Answer D is incorrect. Technician A is correct.
7. Technician A states that some steering shaft universal joints have different splines on
the upper and lower yokes. Technician B says that when instaling the universal joint,
installitonthe lower end of the intermediate shaft first. Who is correct?
A only
B only
Both A and B
Neither A nor B - ANS-Answer A is incorrect. Technician B is also correct.
Answer B is incorrect. Technician A is also correct.
, Answer C is correct. Both Technicians are correct. Some steering shaft universal joints
have different splines on the upper and lower yokes. Be sure the yoke splines and shaft
splines are matched. Also, when installing the universal joint, install it on the lower end
of the intermediate shaft first. Then install the U-joint on the steering gear stub shaft.
Answer D is incorrect. Both Technicians are correct.
A driver complains about rough ride. Which of these would be the LEAST LIKELY
cause?
Excessive positive caster
Leaking or damaged shock absorber
Loose/worn suspension component
Defective rear wheel bearings - ANS-Answer A is incorrect, Excessive positive caster
can cause rough ride characteristics
Answer B is incorrect. A leaking or damaged shock absorber can cause rough ride
characteristics.
Answer C is incorrect. A worn or loose suspension component can cause rough ride
characteristics.
Answer D is correct. Defective rear axle wheel bearings are the exception. Although
defective wheel bearings can be dangerous and generate noise and possible wheel
wobble, they do not usually create a rough ride
When technician is going to check out the front end geometry of a heavy duty tuck,
which of the following steps should be performed first?
Neutralize the suspension by driving the unit back and forth in a straight line.
Jack the front end up and scribe the front tires.
Disconnect the drag link.
Check the over-center adjustment of the steering gear. - ANS-Answer A is correct. The
suspension should be neutralized to take any load or torque off of the suspension and
steering components.
Answer B is incorrect. Scribing the tires is part of the toe setting, which is the last
adjustment made
Answer C is incorrect. It is not necessary to remove the drag link to perform alignment
checks
Answer D is incorrect. Steering gear adjustments have no bearing on steering
geometry.
A driver complains of excessive play in the steering column assembly on a truck
equipped with a tilt steering column. All of the following might be the cause EXCEPT:
