Explain the purpose of a torsion bar in the steering system

If an electrical defect occurs in the electronic power-steering (EPS) system,____. a. the system continues to operate normally, but the EPS warning light is illuminated b. the system continues to operate with a slightly reduced power-steering assist c. the EPS control unit shuts the system down by opening the fail-safe and power relays d. the EPS control unit locks the armature in the steering gear to prevent armature and screw shaft damage

Rack and pinion steering —. a. is lighter in weight and has fewer components than parallelogram steering b. does not provide as much feel for the road as parallelogram steering c. does not use tie-rods in the same fashion as parallelogram steering d. all of the above

Name the three main driveline components that are added to a RWD vehicle to make it a 4WD vehicle.

describe the operation of an electro-hydraulic power steering system (90-120 words)

One of the problems that occur during the designing phase of steering is the choice of Castor angle. What are the problems that may arise in the overall handling and steering of the car due to a castor angle that is either too high or too low?

While diagnosing a loose feeling when steering a vehicle with hydraulic power steering: Technician A says that the problem could be caused by air in the system. Technician B says that the problem could be caused by tight worm shaft thrust bearing preload adjustment. Who is correct?

Answer the following questions 1. How does hydraulic steering works onboard? 2. What is shear force? 3. What is Deflection?

Technician A says that play in the steering gear is the probable cause of a shimmy. Technician B says that it could be loose steering linkage. Who is correct?
