Exam 47: Steering Systems

Power steering hoses must be able to withstand pressures up to _____ psi.

Some tie rod ends use a special bonded ball stud, in which no boot is used.

List four components of a power rack-and-pinion steering system.

Steering dampers are mostly found on vehicles with ____________________ tires.

In a parallelogram steering linkage, one tie-rod end is attached to the wheel's steering arm and the other end is connected to the _____________________.

Electronic rack-and-pinion systems use an electric motor to pump the hydraulic fluid through the hoses.

Hydraulic fluid for the power steering pump is stored in a(n) ____________________.

The worm gear and the pitman gear are components within a recirculating ball steering gearbox.

In a rack-and-pinion steering system, what protects the rack from contamination?

Power rack-and-pinion steering is being discussed. Technician A says the pinion gear functions as the power piston. Technician B says the spool valve is connected to the rack. Who is correct?

What is the primary purpose of power steering hoses?

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?

Electric power steering systems require a steering input torque sensor to determine how much electric current should be sent to the steering assist motor. This torque sensor uses a small ____________________ that is connected between the steering column and the pinion shaft.

If the center tooth on the sector gear is larger than the teeth on either side, the steering box is a _____ type.

Prior to removing the steering wheel on a vehicle equipped with a driver's side air bag, the system must be ____________________.

A sector shaft is used in most rack-and-pinion steering mechanisms.

A variable steering ratio can normally be found in _____ steering units.

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?

A technician is checking a car for loose and erratic steering. When an assistant moves the steering wheel left and right, he notices the entire steering rack moving back and forth about one-half inch. He checks the tightness of the rack mounting bolts and finds that they are torqued to specifications. What could be the problem?

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?
