The manual steering system completely relies on the driver's power for steering, and the mechanical structure is relatively simple, mainly relying on the rack and pinion mechanism to achieve steering. The hydraulic steering system adds a hydraulic power assist device on the basis of the manual.

The biggest advantage of the hydraulic steering system is that it significantly reduces the driver's steering load. In a mechanical steering system, the driver needs to apply a large force to turn the steering wheel, especially when driving at low speed or parking, this force requirement will be more obvious.

Manual steering rack has a simple structure and low cost, but requires the driver to exert greater operating force; while hydraulic steering rack greatly reduces the driver's operating burden through the hydraulic power assist system, but the maintenance requirements are relatively complex and the control feel is slightly reduced.

The repair cost of hydraulic steering system is generally higher, especially when it comes to repairing hydraulic pumps, hydraulic cylinders or steering valves. Because hydraulic systems rely on multiple mechanical and hydraulic components, the cost of repairing and replacing these components can increase significantly.

There may be a variety of reasons why the hydraulic steering rack is not working. These reasons involve multiple components of the system, from the hydraulic pump, the oil pipe, to the hydraulic oil itself, which can be the source of the problem.

The following are some common names for hydraulic steering gears: 1. Power Steering System 2. Assisted Steering 3. Hydraulic Power Steering System 4. Rack and Pinion Steering 5. Hydraulic Assist System

In some cases, the oil leakage problem of the hydraulic steering rack may be caused by the design defects of the vehicle itself. For example, the hydraulic steering system design of some models is not reasonable, resulting in excessive hydraulic oil pressure or excessive stress on the seals, thereby increasing the risk of oil leakage.

Water will freeze below 0 degrees Celsius to form ice cubes, which is fatal to hydraulic systems. In cold environments, if water is mixed into the hydraulic system, the system may lose its function due to the freezing of water.
