What Causes Mercedes-Benz Steering Gear Failure?
1 Answers
Mercedes-Benz steering gear failure is typically caused by excessive air in the power steering system, leading to abnormal vehicle steering; foreign objects in the steering hydraulic lines causing the steering pump flow control valve to stick; or loose connections in the power steering system resulting in steering fluid leakage. Abnormal noise during steering: Solution: The cause of abnormal noise during steering is usually due to damage to the kingpin and bushing or failure of the column thrust bearing. In such cases, you can turn the steering wheel left and right to identify the source of the noise and proceed with disassembly and inspection. Steering gear oil leakage: Solution: Steering gear oil leakage usually occurs at three locations: the upper cover of the steering gear, the connection between the steering shaft and the pitman arm, and the side end cover. This is often due to prolonged use of the vehicle causing sealing issues. Since these areas are equipped with sealing rings, replacing the oil seals and sealing rings can resolve the issue. Difficulty in steering wheel return: Solution: Most vehicles have an automatic steering return function. If you need to apply the same force to return the steering wheel as you do when turning, it indicates a malfunction in the return function. This issue is usually found in the mechanical parts of the steering system, such as lack of lubrication causing damage to the kingpin and bushing, lack of lubrication in the universal joint connecting the steering wheel and steering gear, or rust in the tie rod end due to insufficient lubrication. In such cases, visit a professional repair shop for maintenance.
