Question 1

Technician A says power steering pressure hose leaks can be catastrophic because the fluid is being actively pumped and the fluid could spray all over the hot engine and exhaust system which could cause a fire. Technician B says there will be no noise or warning if the fluid level is very low and the steering will feel fine. Who is correct?

Accepted Answer

Technician A is correct because a power steering pressure hose leak can be catastrophic if the fluid sprays all over the hot engine and exhaust system, which could cause a fire.

Question 2

The height of the vehicle center of gravity is determined by the _______ of the center of mass above the road surface.

Accepted Answer

The height of the vehicle center of gravity is determined by the vertical distance (height) of the center of mass above the road surface.

Question 3

Technician A says flushing the power steering system is to occur whenever the manufacturer specifies a fluid change or whenever the fluid appears to be contaminated or dirty. Technician B says flushing the power steering system is to occur whenever the power steering belt is replaced. Who is correct?

Accepted Answer

Flushing the power steering system is typically recommended when the manufacturer specifies a fluid change or when the fluid appears contaminated or dirty, as stated by Technician A. Replacing the power steering belt does not necessitate flushing the system.

Question 4

The first step to perform a power steering system flush is to:

Accepted Answer

Raising the vehicle is the first step to ensure safety and accessibility when performing a power steering system flush.

Question 5

The first step in removing and replacing the power steering pump is to:

Accepted Answer

Researching the proper procedure is essential to ensure the task is done correctly and safely, as it provides specific instructions and precautions for the vehicle model.

Question 6

Which statement is correct?

Accepted Answer

A power steering system pressure test is typically performed when there are symptoms such as hard steering or repeated hose failures, as these indicate potential issues with the system that need diagnosing.

Question 7

The ________ protect(s) the inner tie-rod ends from dirt and contaminants.

Accepted Answer

Rubber bellows protect the inner tie-rod ends by covering them and preventing dirt and contaminants from entering.

Question 8

The power steering fluid usually has a ______ on the dipstick to ensure an accurate reading of the fluid level.

Accepted Answer

The power steering fluid dipstick typically has a hot indicator and a cold indicator to account for the fluid's expansion and contraction at different temperatures, ensuring an accurate reading.

Question 9

To check for binding issues, it may be necessary to separate the steering linkage to verify that binding is in the _______ or steering column, not the steering linkage or the ball joints.

Accepted Answer

Binding issues can occur in the steering gearbox, which is part of the steering system, and separating the steering linkage helps determine if the problem lies there rather than in the linkage or ball joints.

Question 10

If the customer's concern is related to the steering linkage, perform a visual and hands-on inspection of the ______.

Accepted Answer

A comprehensive inspection of the steering linkage involves checking the linkage itself, the joints, and the steering gear to ensure all components are functioning properly and to identify any issues.

Question 11

The _____ is a flexible ribbon that is coiled inside of a plastic holder.

Accepted Answer

The clock spring is a flexible ribbon that is coiled inside a plastic holder, used in vehicles to maintain electrical connections for the steering wheel controls while allowing the wheel to turn.

Question 12

_____ are designed to collapse in the event of an accident so the steering main shaft in the column does not injure or kill the driver.

Accepted Answer

Steering columns are designed to collapse in the event of an accident to prevent the steering main shaft from injuring or killing the driver.

Question 13

To inspect the __________ for play, position yourself inside the vehicle on the driver's side looking under the dashboard while an assistant pulls and pushes on it.

Accepted Answer

The collapsible steering column is designed to collapse in the event of a collision, reducing the risk of injury to the driver. To inspect the collapsible steering column for play, position yourself inside the vehicle on the driver's side looking under the dashboard while an assistant pulls and pushes on it.

Question 14

________ is when the rear slip angle is larger than the front slip angle; it is referred to as the vehicle being "loose" in the corners.

Accepted Answer

Oversteer occurs when the rear wheels lose grip before the front wheels, causing the rear slip angle to be larger than the front slip angle, making the vehicle feel "loose" in corners.

Question 15

The tire's sideways distortion makes the vehicle follow a path at an angle to the direction the road wheel is pointing in what is called the ________.

Accepted Answer

The slip angle is the angle between the direction the road wheel is pointing and the path the vehicle is following. This is caused by the tire's sideways distortion, which allows the vehicle to turn.

Question 16

The static weight distribution is changed laterally by ________ when the vehicle is turning and in a fore-and-aft direction during acceleration or braking.

Accepted Answer

Centrifugal force acts laterally on a vehicle during a turn, causing a shift in static weight distribution.

Question 17

Dispose of discarded fluid properly in accordance with the relevant ______ and government legislation.

Accepted Answer

The Environmental Protection Agency (EPA) is responsible for regulating the disposal of waste and ensuring it is done in an environmentally safe manner, in accordance with government legislation.

Question 18

The goal for the _______ adjustment is to remove play at the worm bearings while maintaining a low resistance to worm shaft movement.

Accepted Answer

The worm bearing preload adjustment is intended to eliminate play at the worm bearings while ensuring that the worm shaft can still move with minimal resistance.

Question 19

Typically, a power steering system flush is performed with a _______ that is connected in line with the power steering system pump to remove all old dirty fluid and install new clean fluid without introducing air.

Accepted Answer

A flushing machine is used to perform a power steering system flush by connecting it in line with the power steering system pump to remove old fluid and replace it with new fluid without introducing air.

Question 20

A(n) _________ may be spliced into the hose between the steering gear and the pump, or it could fit inside the return hose where the return hose connects onto the pump.

Accepted Answer

An inline filter is designed to be spliced into the hose system, either between the steering gear and the pump or inside the return hose, to filter out contaminants from the fluid.
