A Technician A
B Technician B
C Both A and B
D Neither Technician A or B
Answer C is correct. Both technicians are correct
 
 
3. A technician notices a tire is feathered across its tread. What is the most-likely cause of this condition?
A Caster setting
B Toe setting
C Worn struts
D Camber setting
Answer B is correct. If the toe setting is off feathering of the tire will occur.
 
 
4. Technician A says that a variable rate coil spring has varying spaces between the coils. Technician B says if a vehicle has a noticeable difference in height between sides it may have a weak strut insert.Who is correct?
A Technician A
B Technician B
C Both A and B
D Neither Technician A or B
Answer A is correct. A variable rate spring uses different thickness and spacing between coils.
 
 
5. All these characteristics of camber are true except:
A If camber is negative the tire will wear on the inside tread.
B If camber is different from side to side it will cause a pull.
C Vehicle will pull to the side with the most positive camber.
D Camber is not included in the included angle.
Answer D is correct. The camber angle is included with the SAI to equal the included angle.
 
 
6. Technician A says the total toe is split between the wheels. Technician B says on a 4 wheel alignment always adjust the front toe before the rear. Who is correct?
A Technician A
B Technician B
C Both A and B
D Neither Technician A or B
A. Answer A is correct. The total toe is split between the wheels.

A Technician A
B Technician B
C Both A and B
D Neither Technician A or B
C. Answer C is correct. Some struts have a eccentric camber lobe adjustment. A bad strut tower will make a thumping noise when going over bumps.
 
 
10. Technician A says a worn idler arm will not effect the toe setting on a vehicle. Technician B says the center link of a vehicle connects to both the pitman arm and the idler arm. Who is correct?
A Technician A
B Technician B
C Both A and B
D Neither Technician A or B
B. Answer B is correct. The Center Link of a vehicle connects to both the Pitman Arm and the Idler Arm.
 
 
11. Technician A says it’s important to check tire pressure when the tire is hot. Technician B says the 60 in P225/60R16 89H indicates the tires section width. Who is correct?
A Technician A
B Technician B
C Both Technician A and B
D Neither Technician A or B
Answer D is correct. Neither technician A or B is correct.
 
 
12. Technician A says a vehicle with torsion bar suspension can be adjusted to repair ride height. Technician B says over-adjustment of this type of suspension will result in a harsh ride.
Who is correct?
A Technician A
B Technician B
C Both Technician A and B
D Neither Technician A or B
Answer C is correct. Tightening the adjusting bolt turns a key that adds “twist” to the bar.
 
 
13. A vehicles right front wheel has a growl that increases with vehicle speed. The most likely cause is:
A Excessive Caster
B Excessive Camber
C Worn CV-Joint
D Worn Wheel Bearing
Answer D is correct. A worn out wheel bearing will cause a growl that increases with vehicle speed.
 
 
14. Two technicians are performing a power steering pressure test. Technician A says if the pressure is above specification there may be a restriction in the high pressure line. Technician B says if the pressure increases when the shutoff valve is closed there may be a problem with the power steering pump. Who is correct?
A. Technician A
B. Technician B
C. Both Technician A and B
D. Neither Technician A or B
Answer A is correct. It could also be a damaged power steering gear.
 
 
15. Two technicians are discussing a recirculating ball steering gear. Technician A to adjust the sector shaft lash before the worm bearing preload. Technician B says an under adjusted sector shaft may cause the vehicle to wander. Who is correct?
A. Technician A
B. Technician B
C. Both Technician A and B
D. Neither Technician A or B
Answer D is correct. Both technicians are wrong.
 
 
16. A vehicle has a steady pull to the left. All of these will cause this condition except:
A. The Caster Angle
B. Low Tire Pressure
C. The Camber Angle
D. Steering Universal – Joint
Answer D is correct. A loose steering universal joint will cause play in the steering wheel.
 
 
17. Technician A says a vehicle will pull to the side with the most positive camber. Technician B says that excessive inside tire tread wear could be caused by too much negative camber. Who is correct?
A. Technician A
B. Technician B
C. Both Technician A and B
D. Neither Technician A or B
Answer C is correct. Excessive camber will cause both tire wear and pull.
 
 
18. Two technicians are discussing inner and outer tie rods. Technician A says to turn the outer tie rod end to adjust the toe. Technician B says loose inner tie rod ends will cause a tire to feather. Who is correct?
A. Technician A
B. Technician B
C. Both Technician A and B
D. Neither Technician A or B
Answer B is correct. Loose inner tie rod ends will cause a vehicle to shimmy. Using an inexpensive (hopefully) special tool should greatly reduce labor. The inner tie rod end on a rack and pinion steering system is used to make toe adjustments.
 
 
19. Two technicians are discussing excessive inside tire wear. Technician A says an out of specification caster angle can cause inside tire wear. Technician B says out of specification camber angle will cause excessive tire wear. Who is correct?
A. Technician A
B. Technician B
C. Both Technician A and B
D. Neither Technician A or B
Answer B is correct. Out of specification, camber will result in inside or outside tire wear.

A. Technician A
B. Technician B
C. Both Technician A and B
D. Neither Technician A or B
Answer B is correct. Camber is included in the included angle.
 
 
21. Technician A says the caster angle affects the steering wheels ability to return to center after a turn. Technician B says a binding ball joint has no affect on steering wheel return to center. Who is correct?
A. Technician A
B. Technician B
C. Both Technician A and B
D. Neither Technician A or B
Answer A is correct. Most cars and light trucks have a positive caster setting.
 
 
22. Technician A says a slight oily film on the lower chamber of a shock absorber is acceptable. Technician B says a small drip of oil coming from this chamber is acceptable. Who is correct?
A. Technician A
B. Technician B
C. Both Technician A and B
D. Neither Technician A or B
Answer A is correct. A slight film of oil on a shock absorbers shaft into the chamber is normal.
 
 
23. A vehicle with a ribbed belt makes a chirping noise when starting. Technician A says to check the belt tension with a belt tension gauge. Technician B says proper belt deflection is 1/2 inch per foot of belt span. Who is correct?
A. Technician A
B. Technician B
C. Both Technician A and B
D. Neither Technician A or B
Answer C is correct. Also, if a belt wears excessively on one of the edges check pulley alignment.
