If the leakage is caused by wear of the rack or pinion, then the difficulty of repair will be relatively large. The worn rack surface may cause the seal to fail to seal effectively, which in turn causes hydraulic oil leakage.

The main reasons for Mercedes-Benz power steering system failure: 1. Aging or damage to hydraulic system components 2. Insufficient or contaminated hydraulic oil 3. Electrical failure in the electric steering system 4. Wear of belts or pulleys 5. Mechanical problems in the steering system 6. Inadequate maintenance or improper use

From Toyota and Ford to BMW and Mercedes-Benz, these brands still choose hydraulic steering systems on some models because of their excellent reliability, excellent driving feedback and low manufacturing and maintenance costs.

The driver needs to exert more force when steering, which is especially dangerous for inexperienced drivers. In an emergency, the lack of steering power may cause the vehicle to fail to avoid obstacles in time or make correct steering operations, causing accidents.

Open the owner's manual and find the vehicle specifications or technical parameters section. Generally, the type of power steering system will be listed here. If the manual specifically mentions "hydraulic power steering system" or "electronic power steering system", then you can determine the vehicle's equipment.

A damaged steering rack may cause inaccurate steering of the vehicle. This phenomenon is usually manifested as the actual steering angle of the vehicle does not match the expected one after the driver turns the steering wheel, or the steering response is slow.

Mercedes-Benz first adopted power steering systems in its mass-produced models in 1958. The system was first used in the Mercedes-Benz 300 Series sedan (W189), a high-end luxury sedan favored by aristocrats and business elites.

When the driver hears abnormal squeaks or grinding noises when turning the steering wheel, this is often a sign of worn or insufficient lubrication of the rack and pinion. If these noises persist and become more severe, it may mean that the rack and pinion are damaged and need to be replaced.

The power steering pump (Power Steering Pump) is one of the key components in the power steering system. Its main function is to generate hydraulic oil flow through mechanical force to provide power to the steering 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.
