Using the wrong type of fluid can cause damage to the power steering system and potentially lead to expensive repairs. It is important to follow the manufacturer's recommendations to ensure proper functioning and longevity of the power steering pump.

Rubber bellows are designed to protect the inner joints from dirt and contaminants. These bellows act as a flexible cover that surrounds the joints, preventing any foreign particles from entering and causing damage. By keeping the joints clean and free from debris, the rubber bellows help to maintain the smooth operation and longevity of the inner joints.

The correct answer is Rudolph Ackermann. The steering geometry is named after him because he invented the Ackermann steering mechanism in 1817. This mechanism allows all four wheels of a vehicle to turn at different angles, ensuring that the inner and outer wheels follow different turning circles. This design improves the vehicle's maneuverability and reduces tire wear.

The pinion gear is a tooth gear that meshes with the rack. It is commonly used in mechanical systems to transfer rotational motion from one component to another, such as in a steering system or a differential. The pinion gear has teeth that engage with the teeth on the rack, allowing it to convert rotational motion into linear motion or vice versa. This gear is typically smaller in size compared to other gears in the system and is designed to provide high speed and torque transmission.

The most common type of steering system used on vehicles today is the rack and pinion. This system consists of a rack (a long, straight bar with teeth) and a pinion (a small gear). When the driver turns the steering wheel, the pinion gear rotates and moves the rack sideways. This movement translates into the wheels turning left or right, allowing the vehicle to change direction. The rack and pinion system is popular due to its simplicity, compactness, and efficient power transfer, making it the preferred choice for modern vehicles.

The correct answer is hydraulic because the question states that the power steering pump applies assist to hydraulic brakes on some vehicles. This implies that the power steering pump is hydraulic and not fully electric or electric powered.

Bump steer is the undesired condition produced when, upon hitting a bump, the vehicle darts to one side as the steering linkage is pushed and pulled as a result of the travel of the suspension. This means that the vehicle's steering is affected and becomes unstable when encountering bumps on the road. It can be dangerous as it can cause the vehicle to veer off course and potentially lose control.

The bead of a tire is the belt reinforced, inner edge that seals the rubber of the tire to the metal of the rim.

The pitman arm transfers movement from the steering box to the center link. It is a connecting arm that is attached to the steering gear and helps to convert the rotational motion of the steering box into the linear motion needed to turn the wheels. The pitman arm is an essential component of the steering system and plays a crucial role in controlling the direction of the vehicle.

A dial indicator is used to measure the run-out or movement on different parts of the steering system, such as play in tie rod ends. It is a precision measuring tool that provides accurate readings of small distances or movements. By placing the dial indicator against the steering components and rotating them, any excessive play or movement can be detected and measured. This helps in identifying and correcting any issues with the steering system, ensuring proper functionality and safety.

Tech B is correct. The rack is directly connected to the tie rod assembly. The tie rod assembly is responsible for transmitting the steering input from the rack to the steering knuckle, which then controls the movement of the wheels. Tech A's statement is incorrect as the rack is not directly connected to the steering knuckle.

Tech B is correct. The rack-and-pinion system is known for providing greater road feel compared to the worm gear. The rack-and-pinion system consists of a rack (a linear gear) and a pinion (a small gear) that work together to convert the rotational motion of the steering wheel into linear motion, allowing for more direct and responsive steering. On the other hand, the worm gear system uses a worm gear and a sector gear, which can result in a smoother but less direct steering feel.

The correct answer is rack and pinion and parallelogram. These are the two main types of steering systems used on vehicles today. Rack and pinion steering utilizes a gear mechanism to convert the rotational motion of the steering wheel into linear motion, which then moves the wheels. Parallelogram steering, also known as recirculating ball steering, uses a series of linkages and a steering box to transmit the motion from the steering wheel to the wheels. Both systems are commonly found in different types of vehicles and have their own advantages and disadvantages.

The power steering pump reservoir can be either mounted directly to the pump or remotely mounted. This means that it can be located either on the pump itself or placed at a distance from the pump, depending on the specific design of the vehicle's power steering system. Therefore, the correct answer is both A and B.

Excessive looseness in a power steering gear can be caused by a loose worm shaft bearing preload adjustment. The worm shaft bearing is responsible for maintaining the proper tension and stability of the steering gear. If the preload adjustment is loose, it can result in excessive play and looseness in the steering gear, causing difficulties in steering the vehicle. Therefore, ensuring the proper adjustment of the worm shaft bearing preload is crucial for maintaining the functionality of the power steering gear.

Over inflation causes the tire to peak. The result is a tire that rides mostly on the center part of the tread, and wearing that part more quickly.

A bulge on the side of a tire indicates a broken belt on the inside of the tire.

The steering knuckle is responsible for connecting the wheels to both the suspension and steering system. It is a crucial component that allows the wheels to turn and pivot as directed by the driver's input through the steering system. By connecting the wheels to the suspension, the steering knuckle helps to absorb shocks and maintain stability while driving. It also plays a role in maintaining proper alignment and steering control.

A steering damper is a device that helps to reduce the impact of shock forces on the steering system. It is designed to absorb and dissipate these forces, preventing them from being transmitted through the steering linkage and back to the steering wheel. This helps to improve steering stability and control, especially when encountering bumps or uneven surfaces. The steering damper acts as a buffer, reducing vibrations and sudden jolts that could otherwise affect the steering performance and make it harder for the driver to maintain control of the vehicle.

A scan tool is used to read codes and data from the vehicle's power train control module (PCM) when diagnosing the vehicle's computer-controlled systems. It is a diagnostic tool that connects to the vehicle's onboard computer system and retrieves information about the various systems and components. By using a scan tool, technicians can identify any potential issues or malfunctions in the vehicle's computer-controlled systems and make the necessary repairs or adjustments.

Tech B is correct. Collapsible steering wheels/columns are designed to absorb impact and reduce the risk of injury in an accident. The collapsible section allows the steering wheel/column to collapse or retract upon impact, minimizing the force transferred to the driver or passengers. This safety feature is commonly found in modern vehicles to enhance occupant protection during collisions. Tech A's statement about a break-off steering wheel is not accurate or supported by current automotive safety standards.

The tire sidewall provides the maximum pressure for the tire. Vehicles each have their own specific tire pressure.

The term "steering geometry" refers to the relationship between the steering system, wheel positions, and the suspension system. It encompasses the angles and adjustments that determine how the wheels turn and respond to steering inputs. This includes factors such as the caster angle, camber angle, and toe angle, which all play a role in determining the vehicle's handling and stability. By understanding and adjusting the steering geometry, mechanics and drivers can optimize the performance and safety of the steering system.

The correct answer is to research the proper procedure. Before attempting to remove and replace the power steering pump, it is important to gather all the necessary information and understand the correct steps involved in the process. Researching the proper procedure ensures that the task is performed correctly and reduces the risk of causing damage to the vehicle or injury to oneself. It is crucial to have a clear understanding of the steps involved, such as disconnecting hoses and drive belts, as well as any specific tools or precautions that may be required.

Tech B is correct. The steering wheel transmits the driver's steering effort from the steering wheel to the steering box. The steering column, on the other hand, connects the steering wheel to the steering mechanism and helps to transfer the rotational movement of the steering wheel to the steering box.

Low fluid level in the power steering system can cause air bubbles to form in the fluid. When the fluid level is low, there may not be enough fluid to properly lubricate and cool the power steering pump. This can result in air being drawn into the system, leading to the formation of air bubbles in the fluid. These air bubbles can cause noise, reduced power steering performance, and potential damage to the power steering components. Therefore, maintaining the proper fluid level is important to prevent the occurrence of air bubbles in the power steering fluid.

The clock spring is responsible for maintaining continuous electrical contact with the airbag as the steering wheel is turned from lock to lock. It is a coiled wire that allows for the rotation of the steering wheel while still providing a connection for various electrical components, such as the horn, cruise control, and airbag. This ensures that these components remain functional even when the steering wheel is turned in different directions.

A tire's pressure will be effected 1psi by a change in 10 degrees F. Tire pressure specifications are given when the tire is cold and should only be adjusted when they are such.

Tech A is correct because a faulty power steering pump can cause a whining noise when turning. The power steering pump is responsible for providing hydraulic pressure to assist with steering, and if it is faulty, it may not be able to function properly when turning, resulting in a whining noise. Tech B's suggestion of a worn left front wheel bearing may also cause noise, but it is not specific to turning and may be a separate issue.

The correct answer is D because a cracked bellows boot indicates that there may be damage to the inner tie-rod. Therefore, the tech should inspect and/or replace the inner tie-rod and also replace the bellows boot to ensure proper functioning of the rack and pinion system. Simply using a silicone sealer or ignoring the issue would not address the underlying problem and could lead to further damage or malfunction.

Each tie rod on each side of the vehicle connects the wheel assembly to the center link. The tie rod is a crucial component of the steering system, and it helps to transmit the steering input from the center link to the wheel assembly, allowing for smooth and controlled steering of the vehicle. By connecting the wheel assembly to the center link, the tie rod ensures that the steering motion is translated accurately and efficiently, enabling the driver to maneuver the vehicle effectively.

Both Techs A and B are correct. Tech A is correct in stating that the basic steering system has four main parts: a steering column, a steering box, a steering linkage, and a steering knuckle. Tech B is also correct in stating that the most basic steering systems have a power assist.

Both the center link and the drag link are responsible for connecting the pitman arm to the idler arm. The center link, also known as the relay rod or tie rod, connects the pitman arm to the idler arm, while the drag link connects the pitman arm to the steering arm on the steering knuckle. Both of these components play a crucial role in the steering system, allowing the driver to control the direction of the vehicle. Therefore, the correct answer is Both A and B.

Tech B is correct. The main problems in the power steering system are play and hard steering, not leaks. Leaks can be a problem in the power steering system, but they are not one of the main problems. Play refers to excessive movement or looseness in the steering system, while hard steering refers to difficulty in turning the steering wheel.
