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. - CORRECT ANSWER- 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 - CORRECT ANSWER- 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 - CORRECT ANSWER- 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 - CORRECT ANSWER- 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. - CORRECT ANSWER- 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 - CORRECT ANSWER- 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 - CORRECT ANSWER- 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
