Steering wheel, driving these cars may have been easy on the driver’s arms but not so on their legs, for the driver and passengers often walked home after the car skittered off the road. To be up close and personal with ditches was not a desired condition, but it was a frequent one.
With the introduction and acceptance of wider tires, vehicles stayed on the road better, but they were more difficult to park in small spaces. Parking a car weighing more than 2,000 pounds became a chore fit only for weightlifters.
Power steering adds the turning power of the engine to the turning power of the steering gears. This assistance comes from a belt-driven power steering pump. This pump pressurizes the power steering fluid, which is held in a reservoir. The fluid pressure increases turning power. Consequently, less manual pressure is needed to turn the steering wheel.
