A driver complains about rough ride. Which of these would be the
LEAST LIKELY cause?
A. Excessive positive caster
B. Leaking or damaged shock absorber
C. Loose/worn suspension component
D. Defective rear wheel bearings
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.
All of the following are a function of the torque arm EXCEPT:
A. To retain axle alignment.
,B. To control axle torque.
C. To control ride height.
D. To adjust axle alignment.
Answer A is incorrect. Retaining axle alignment is a function of the
torque arm.
Answer B is incorrect. Controlling axle torque is a function of the
torque arm.
Answer C is correct. Controlling ride height is not a function of the
torque arm.
Answer D is incorrect. Adjusting axle alignment is a function of the
torque arm.
While discussing wheel balance, Technician A says that dynamic
wheel balance is better than static balance because it is performed
with the wheel stationary. Technician B says that dynamic wheel
balance is better than static balance because you can tell if the
wheel is bent.
Who is correct?
A. A only
B. B only
C. Both A and B
D. Neither A nor B
Answer A is incorrect. Dynamic balancing is performed with the tire
rotating.
Answer B is correct. Only Technician B is correct. Dynamic
balancing can detect a bent wheel rim. When a dynamically
unbalanced wheel is rotating, the heavy spot moves around the tire
causing lateral wheel shake or shimmy.
Answer C is incorrect. Only Technician B is correct.
Answer D is incorrect. Technician B is correct,
Technician A says that when reinstalling rubber-bushed equalizing
beams, you should install the torque rods before torquing the beam
end bolts to specification. Technician B says that you should ensure
,the beams are parallel to the frame rails. Who is correct?
A. A only
B. B only
C. Both A and B
D. Neither A nor B
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. Installing the
torque arms prior to tightening the beam end bolts allows the beam
to move slightly if needed and does not load up the suspension. The
beams should be parallel to the frame frail so the suspension tracks
correctly.
Answer D is incorrect. Both Technicians are correct.
Which of the following is the most likely cause of steering wheel
shimmy?
A. A toe-in setting that is too high
B. Improper dynamic wheel balance
C. An excessive load in the vehicle
D. A toe-out setting that is too high
Answer A is incorrect. A toe-in setting that is too high will cause
excessive tire wear.
Answer B is correct. Improper dynamic wheel balance can cause
steering wheel shimmy.
When the wheel rotates until the heavy spot is at the front of the
wheel, the heavy spot movement turns the left-front wheel outward,
causing lateral wheel shake or shimmy.
Answer C is incorrect. An excessive vehicle load might cause a
wander and weave condition because not enough weight is
transferred to the steer axle, but will not cause wheel shimmy.
Answer D is incorrect. A toe-out setting that is too high cannot cause
steering wheel shimmy. Toe only affects directional stability and tire
wear.
, A technician has checked the pulley alignment on a power steering
system and found them to be misaligned. All of the following could
cause the power steering pump pulley to become misaligned
EXCEPT:
A. An overpressed pulley.
B. Loose fit from pulley hub to pump shaft.
C. A worn or loose pump mounting bracket.
D. A broken engine mount.
Answer A is incorrect. An overpressed pulley could cause the power
steering pump pulley to become misaligned,
Answer B is incorrect, A loose fit from the pulley hub to the pump
shaft could cause the power steering pump pulley to become
misaligned.
Answer C is incorrect, A worn or loose pump mounting bracket could
cause the power steering pump pulley to become misaligned.
Answer D is correct. A broken engine mount will not cause the
power steering pump pulley to become misaligned. All of the
components would still move in unison; the whole engine assembly
would move.
The unitized wheel end may be described as:
A. Easily identifiable by the two distinct star shapes embossed on the
center of its hubcaps.
B. An enclosed unit with bearings that will need to be serviced every
100,000 miles.
C. An enclosed unit with bearings that will need to be serviced every
500,000 miles.
D. An enclosed unit with bearings lubricated for the life of the hub,
bearing, and seal assembly.
Answer A is incorrect. The embossed shapes on the hubcaps are
half moon shapes.
Answer B is incorrect. Unitized wheel end components are not
serviceable. If a failure occurs, the hub assembly will need to be
replaced.
