Exam 47: Steering Systems

What is a dry park check?

Technician A says an electronically controlled power steering system provides power assistance when the engine stalls. Technician B says an electronic rack eliminates the hydraulic pump and hoses. Who is correct?

Which of the following would NOT cause excessive play in the steering wheel?

Active steering systems are being discussed. Technician A says active steering improves vehicle stability by turning the wheels more or less sharply than commanded by the steering wheel. Technician B says the system allows for a variable steering ratio dependent on vehicle speed. Who is correct?

The ____________________ arm connects to the frame at the opposite side of the center link from the pitman arm.

What should you look for when checking a power steering pump drive belt?

The function of the balls in a recirculating ball-type steering gear is to _____.

Which of the following is NOT a probable cause of wheel shimmy?

Front-wheel suspension design greatly influences steering geometry.

Power steering fluid pressure can be measured with a scan tool.

If the center link, idler arm, or pitman arm is NOT mounted at the correct height, the toe is unstable, and a condition known as _____ occurs.

Mechanical 4WS is steering angle sensitive but not sensitive to vehicle road speed.

Rack-and-pinion steering arrangements require two tie-rod linkages.

Technician A says some tie-rod ends use a special bonded ball stud without a boot. Technician B says when checking tie-rod ends, any vertical movement of the tie-rod over 1/8 inch (3 mm)indicates that replacement is necessary. Who is correct ?

Parallelogram steering arrangements typically use a rack and pinion mechanism.

In an electric steering system the _____ must be recalibrated to its zero point whenever the steering gear, steering wheel, steering column, or steering control module has been removed or replaced.

Technician A says a special puller is often required to separate a tie-rod end from the steering knuckle. Technician B says a special puller is required to separate the pitman arm from the pitman shaft. Who is correct?

Wear and looseness in a parallelogram-type steering linkage permits intermittent changes in the toe setting of the front wheels; this can lead to ________.

In a rack-and-pinion steering system, the ____________________ performs the task as the center link in a parallelogram-type steering system.

Power steering systems are being discussed. Technician A says an integral systems has the power cylinder and the control valve located inside the same housing as the steering gear. Technician B says an external piston linkage system has the power cylinder and control valve located externally, between the center link and the frame. Who is correct?
