Front 7

7: When dismounting a tire from a wheel, which of the following is the FIRST step to perform?

[>] Dynamic imbalance

Front 11

1: Techs A and B are discussing diagnosis of electric power steering (EPS) systems. Tech A says that the EPS system can self-diagnose by monitoring the system’s inputs and outputs and the driving current of the motor. Tech B says that a digital volt-ohmmeter is not needed to find breaks in the system’s wiring. Who is correct?

Back 11

[>] Tech A

Front 12

2: What is the main advantage of using a parallelogram steering linkage and a worm gearbox in four-wheel drive vehicles designed for off-road use?

3: Which of the following alignment angles uses the Ackermann principle?

Back 13

[>] Toe-out on turns

Front 14

4: When flushing the power steering fluid, Tech A says that all of the fluid can be exchanged using a suction gun or pump. Tech B says that fresh fluid must be pumped through the steering gear and hoses by turning the steering from lock to lock with the return hose disconnected and fresh fluid being fed into the reservoir. Who is correct?

Back 14

[>] Tech B

Front 15

Back 18

[>] Research the service information for procedures and specifications.

Front 19

9: A customer complains of hard and erratic steering on a vehicle equipped with electric power steering (EPS). When you check the vehicle, the EPS light is not on and the steering operation feels normal in the shop. Which of the following should you do next?

Back 19

[X] Road test the vehicle to verify the complaint.

Front 20

10: Inspection of the steering column-to-gear universal joint or flex coupling should be done:

Front 21

1: If rear wheel thrust angle is incorrect, which of the following will occur?

Back 21

[X] The rear of the vehicle will try to steer in the direction the wheels are pointing and the vehicle will “crab walk.”

Front 22

2: True or False. The greater the unsprung mass of a vehicle, the harder it will ride and the harder it will be to control.

Back 22

[>] TRUE

Front 23

3: With respect to coil spring suspension, Tech A says that cylindrical springs give more suspension travel than conical or barrel springs. Tech B says that progressive rate springs provide a smoother ride when the vehicle is lightly loaded. Who is correct?
