✔✔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 - ✔✔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.
✔✔The alignment angle that is LEAST LIKELY to cause the greatest tire wear is:
A. Castor.
B. Turning radius.
C. Toe-in.
D. Camber. - ✔✔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 reversed.
Answer D is incorrect. Camber can cause tire wear but not as great a tire wearing angle
as toe-in.
✔✔Technician A states that some steering shaft universal joints have different splines
on the upper and lower yokes. Technician B says that when installing the universal joint,
install it on the lower end of the intermediate shaft first. Who is correct?
A. A only
B. Bonly
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. 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.
✔✔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. Aonly
B. Bonly
C. Both A and B
D. Neither A nor B - ✔✔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. A only
B. Bonly
C. Both A and B
D. Neither A nor B - ✔✔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.
✔✔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.
