The Chevrolet Caprice Steering Gear, or the Steering box is located at the end of the steering shaft and has a worm type gear that allows the input of the steering wheel to turn the front wheels. Most Chevrolet Caprice steering boxes have power assist that is driven by the power steering pump. Most Chevrolet Caprice steering boxes fail due to inadequate lubrication, so make sure you have plenty of power steering fluid at all times.
Like any other hose, the Chevrolet Caprice power steering hose can eventually develop leaks and need replacement. If you check the Chevrolet Caprice Power steering hose and see small hairline cracks it would be a good time to replace the power steering hose.
