Question 1

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 ?

Accepted Answer

Technician A is correct because some tie-rod ends do use a bonded ball stud design that doesn't require a boot. Technician B is also correct because excessive vertical movement in tie-rod ends can indicate wear, and over 1/8 inch is generally considered excessive.

Question 2

Technician A says the parallelogram-type of steering linkage can be mounted ahead of the front suspension. Technician B says the parallelogram-type of steering linkage can be mounted behind the front suspension. Who is correct?

Accepted Answer

The parallelogram-type of steering linkage is versatile and can be mounted either ahead of or behind the front suspension, making both Technician A and Technician B correct.

Question 3

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.

Accepted Answer

Bump steer occurs when the toe changes as the suspension moves up and down, which can happen if components like the center link, idler arm, or pitman arm are not mounted at the correct height.

Question 4

The main job of the idler arm is to support the _____.

Accepted Answer

The idler arm supports the right side of the center link in a vehicle's steering system, helping to maintain proper alignment and steering stability.

Question 5

Which of the following is a 4WS production design?

Accepted Answer

4WS (Four-Wheel Steering) systems can be designed using mechanical, hydraulic, or electro/hydraulic methods. Each of these approaches can effectively change the direction of the vehicle's rear wheels in coordination with the front wheels to improve maneuverability, stability, and handling. Therefore, all the mentioned options are correct forms of 4WS production designs.

Question 6

Technician A says that worn tie-rod ends are the probable cause of a shimmy. Technician B says that a shimmy could be caused by a loose power-steering belt. Who is correct?

Accepted Answer

The answer of Technician A says that worn tie-rod ends...

Question 7

Quadrasteer steering systems are being discussed. Technician A says at low speeds, the rear wheels turn in the same direction as the front wheels. Technician B says at high speeds, the rear wheels turn in the direction opposite to the front wheels. Who is correct?

Accepted Answer

At low speeds, the rear wheels turn in the opposite direction to the front wheels to reduce turning radius and improve maneuverability. At high speeds, the rear wheels turn in the same direction as the front wheels to improve stability, especially during lane changes.

Question 8

Technician A uses a torque wrench to measure bearing drag when making steering gear adjustments. Technician B uses a pull scale to determine whether the actual steering force is within specifications. Who is correct?

Accepted Answer

Technician A is correct because a torque wrench can be used to measure the resistance or drag in bearings. Technician B is also correct because a pull scale can be used to measure the force required to turn the steering wheel, ensuring it is within specifications.

Question 9

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

Accepted Answer

The answer of Wear and looseness in a parallelogram-type steering...

Question 10

Which of the following is NOT part of a parallelogram-type steering linkage?

Accepted Answer

The control arm is not part of a parallelogram-type steering linkage; it is instead a component of the vehicle's suspension system, connecting the chassis to the wheels and allowing for motion control.

Question 11

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?

Accepted Answer

Both technicians are correct. An electronically controlled power steering system can provide power assistance even when the engine stalls because it is not dependent on the engine running to operate, as it uses electric motors instead of hydraulic pressure generated by the engine. Technician B is correct because an electronic rack (part of an electric power steering system) eliminates the need for a hydraulic pump and hoses, replacing them with electric components.

Question 12

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?

Accepted Answer

Both Technician A and Technician B are correct. In an integral system, the power cylinder and control valve are indeed located inside the same housing as the steering gear. In an external piston linkage system, the power cylinder and control valve are located externally, typically between the center link and the frame.

Question 13

What component connects the steering gearbox to the steering linkage?

Accepted Answer

The Pitman arm is the component that connects the steering gearbox to the steering linkage, converting the angular motion from the sector shaft into linear motion needed for steering.

Question 14

Rack-and-pinion steering ______.

Accepted Answer

The answer of Rack-and-pinion steering ______.
...

Question 15

Steering dampers are being discussed. Technician A says a light film of fluid is permissible on the body of the damper near the shaft seal. Technician B says steering dampers can be repaired and refilled. Who is correct?

Accepted Answer

A light film of fluid on the body of the damper near the shaft seal is considered normal due to the weeping of fluid for lubrication purposes. Steering dampers are typically not repairable or refillable; they are replaced when they fail.

Question 16

All steering systems have a ______.

Accepted Answer

All steering systems indeed have a linkage, steering gear, and a steering column and wheel, making all the provided options correct components of a steering system.

Question 17

Which statement about the integral-piston power steering linkage system is true?

Accepted Answer

The integral-piston power steering linkage system is characterized by the power cylinder being integrated with the steering gear, making option A correct. Options B and C describe features that are not typical of an integral-piston system, where the power assist mechanism is built into the steering gear itself, rather than being a separate component or having multiple hydraulic lines connected directly to the power cylinder.

Question 18

Technician A says adjusting the steering gear too tightly can cause hard steering. Technician B says adjusting the steering gear too tightly can cause poor returnability. Who is correct?

Accepted Answer

Both technicians are correct. Adjusting the steering gear too tightly can cause hard steering because it increases the effort required to turn the steering wheel. It can also cause poor returnability, which is the steering wheel's ability to return to the neutral or straight-ahead position after a turn, because the excessive tightness restricts the free movement of the steering components.

Question 19

Rack and pinion steering systems are being discussed. Technician A says they do not require inner tie-rod ends. Technician B says they require two outer tie-rod ends. Who is correct?

Accepted Answer

Rack and pinion steering systems do require inner tie-rod ends to connect the rack to the steering knuckles, and they also require two outer tie-rod ends to connect to the wheels. Therefore, Technician B is correct.

Question 20

Technician A says a worn or damaged idler arm can cause front-end shimmy. Technician B says a worn or damaged idler arm can cause hard steering. Who is correct?

Accepted Answer

Both technicians are correct. A worn or damaged idler arm can cause front-end shimmy due to the instability it introduces to the steering system, and it can also lead to hard steering because it affects the smooth operation of the steering linkage.
