What causes the heavy steering in Mercedes-Benz R350?

[LeLeilani]

Heavy steering in Mercedes-Benz R350 is caused by a faulty power steering pump or insufficient oil. Causes and solutions for automotive steering system failures: Abnormal noises during steering are generally caused by 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. Power steering fluid leakage and solutions: Leakage in the steering gear typically 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 usually due to seal deterioration from prolonged vehicle use. Since all three locations have sealing rings, replacing the oil seal and sealing rings can resolve the issue.
