Start

1. On cold mornings, the warning lamp on a vehicle with a TPMS tire pressure monitoring system stays illuminated for several minutes before it goes out. Which of these is MOST likely the cause of this condition.

Worn tread on one of the tires.
TPMS initialization.
Low tire pressure.

Technician A
Technician B
Both A and B
Neither A or B

3. There is noticeable wear on the left front tire of a rear wheel drive vehicle. The technician suspects the camber angle is out of specification. All these characteristics of camber are true EXCEPT:

Negative camber causes wear on the tires inside tread.
An out of specification camber angle will result in a steering pull condition.
The vehicle will pull to the side with the most positive camber.
Camber is not included in the included angle.

4. A vehicle pulls to the right and makes a clunking sound when the brakes are applied. During an alignment check the technician notices excessive negative caster on the right front wheel. Technician A says this is most likely caused by a seized brake caliper. Technician B says this is most likely caused by worn or missing strut rod bushings. Who is correct?

Technician A
Technician B
Both A and B
Neither A or B

5. Two technicians are discussing an air bag solenoid located on the top of the air bag. Technician A says this valve is used to inflate the air bag. Technician B says this valve is used to deflate the air bag. Who is correct?

Technician A
Technician B
Both A and B
Neither A or B

6. Technician A says the vehicle in the chart above is within specifications. Technician B says the vehicle's front toe is out of specifications. Tire wear will result from this condition. Who is correct?

Technician A
Technician B
Both A and B
Neither A or B

7. There is a growling sound on the RF of a passenger car that changes pitch on different road surfaces. Which of the following is MOST likely causing this condition?

Cupped tires.
Bad wheel bearing.
Excessive positive caster.
Excessive negative caster.

8. The steering wheel grabs and binds only at certain points along the steering wheel’s rotation. Technician A says the steering shaft universal joint is binding and should be inspected for wear. Technician B says the intermediate shaft may need to be replaced. Which technician is correct?

Technician A
Technician B
Both A and B
Neither A or B

9. There’s a squeak in the steering column when the steering wheel is turned in either direction. All of the following components will result in a noisy steering column EXCEPT.

Steering coupling.
Clockspring
Steering column bearings.
Horn switch.

10. Two technicians are discussing tie rod ends. Technician A says loose tie rod ends result in wander while attempting to steer straight. Technician B says to rock the tire back and forth at the three and nine o’clock positions to check for tie rod looseness. Who is correct?

Technician A
Technician B
Both A and B
Neither A or B

11. The vehicle in the alignment chart above has excessive shimmy above 45 mph. The MOST likely cause of this condition is:

Camber
Wheel Balance
Toe
Caster

12. A vehicle with a power rack and pinion steering system doesn't return to center after completing a turn. Technician A says an incorrect caster angle will cause this condition. Technician B says a binding lower ball joint would have no affect on steering wheel return to center. Who is correct?

Technician A
Technician B
Both A and B
Neither A or B

13. A technician is replacing weak coil springs on a light truck with coil spring suspension. Which of the following are not used to support a solid axle with this type of suspension?

Track Bars
Pitman Arms
Control Arms
Strut Rods

14. Two technicians are discussing struts on a front wheel drive vehicle. Technician A says some struts have a camber lobe adjustment. Technician B says a worn strut tower will make excessive noise when going over bumps. Who is correct?

Technician A
Technician B
Both A and B
Neither A or B

15. Which of the following is true about the tire in the illustration?

It is underinflated.
It is overinflated.
There is too much camber.
The coil spring on that wheel is weak.

16. A technician is using a steel hammer to remove a loose tie rod end from an aluminum steering knuckle. Which of the following is correct?

Care should be taken not to strike the threaded ball socket.
Care should be taken not to strike the loose tie rod end.
Use a puller not a hammer to remove the tie rod end from the steering knuckle.
Use a puller to apply pressure while striking the steering knuckle with moderate force to remove the loose tie rod end.

17. Technician A says Electric Power Steering systems require inputs from the steering torque sensor and the vehicle speed sensor to operate the system's electric motor. Technician B says to use a scan tool to retrieve trouble codes from an EPS system. Who is correct?

Technician A
Technician B
Both A and B
Neither A or B

18. Component A in the illustration above:

Is part of the vehicle’s shock absorbing system.
Absorbs impact as a vehicle travels over potholes and bumps in the road.
Can be found on both front and rear suspension systems.
All of the above.

19. Which of the following is used to flush old dark colored power steering fluid from a hydraulic power steering system?

Solvent
