Exam 11: Steering Systems

There are four primary types of electric power assist steering systems, including all of the following EXCEPT:

Reduction ratio is measured in:

Power-assisted steering uses a(n) _________ that aids the driver in turning the wheel.

Which of the following electric power assist steering systems has the power assist unit, controller, and torque sensor connected to the steering column?

Technician A says that the steering torque sensor and the steering angle sensor are compared to determine the amount of electrical assist that is needed. Technician B says that a steering angle sensor may need to be calibrated after performing certain repairs. Who is correct?

The steering box converts the rotary motion of the steering wheel into:

In modern computer-controlled four-wheel steering, an actuator similar to a front rack-and-pinion assembly attaches to the rear steering knuckles with:

Tech A says that the steering gear is directly connected to the steering knuckle. Tech B says that the steering gear is directly connected to the tie rod assembly. Who is correct?

There are three types of power steering, including all of the following EXCEPT:

As the driver turns the steering wheel, the ______ mechanism moves the steering linkages via the pitman arm either left or right, depending on the direction in which the steering wheel is turned.

The _________ converts the rotary motion of the steering wheel into the linear motion needed to pivot the wheels.

The ______ use(s) principles of gear reduction to give the driver mechanical advantage over the wheels, making it easier to steer them.

The steering sensor is located on the ________, where it is bolted down.

Reduction ratio is measured in:

Tech A says that when the vehicle is being driven straight ahead, a belt-driven power steering pump will pump fluid continuously, placing a minimal load on the engine. Tech B says that a belt-driven power steering pump is activated by an electromagnetic clutch, so it only pumps fluid when the wheels are being steered. Who is correct?

The ______ transfers the linear steering effort to the wheels by connecting the steering box to the steering arm on each of the steering knuckles, which pivot on the ball joints, allowing the wheels to steer the vehicle.

The ________ is a rotating gear that meshes with the rack.

Technician A says that power steering fluid is universal and can be used in virtually any vehicle's power steering system. Technician B says that in a power steering system, the force needed to turn the wheels is created by the hydraulic pump or electric motor. Who is correct?

Tech A says that steering boxes can be either manual or power assisted. Technician B says that there are two types of steering boxes: road-force-isolating-ball-bearing and worm gear. Who is correct?

The _________ normally has an adjustable bushing positioned opposite the pinion to control the components' meshing, and it has a nylon bushing at the other end.
