Final answer:
Three other parts of a vehicle's steering system are the tie rods, which link the steering arm to the steering rack; the steering rack, which translates rotational motion to lateral motion for wheel turning; and the pinion, a gear that connects with the steering rack allowing the steering wheel's rotation to steer the vehicle.
Step-by-step explanation:
The question asks about other parts of a vehicle's steering system beyond the wheel, shaft, power cylinder, and arm. Three other parts that are integral to the steering system of a vehicle are the tie rods, the steering rack, and the pinion. The tie rods connect the steering arm to the steering rack and help to push and pull the front tires as the wheel turns.
The steering rack is a linear gear that interfaces with the pinion, converting the rotational motion of the steering wheel into the lateral motion that actually turns the vehicle's wheels. Lastly, the pinion, which is a small gear, engages with the steering rack and is turned directly by the steering shaft, allowing the driver's rotational input to be transmitted to the steering rack.
While window control, cruise control button, interior steering wheel, radio volume knob, gear shifter, and center console are parts of a vehicle's interior controls, they are not specifically parts of the steering system.
