Questions with Verified Answers (2026)
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 answers -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 answers -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 answers -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 answers -Answer A is incorrect. A loose idler arm will cause
fluctuation in the steering when striking a bump.
2
,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 answers -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 answers -Answer A is incorrect. The front wheels need to be in a toe-in
condition.
3
, 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 answers -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 - correct answers -Answer A is incorrect. Technician B is also correct.
Answer B is incorrect. Technician A is also correct.
