The most common locations for power steering system oil leaks are concentrated in three key parts of the steering gear assembly: the upper cover of the steering gear, the side end cover, and the connection of the steering shaft crank arm. In addition, common oil leakage points also include the damaged seal at the rear end of the power steering pump, seal wear caused by the rupture of the dust cover, and loose or aging joints of the power steering oil pipeline. For minor cracks, high-permeability sealant can be used for temporary repair. However, if the oil leakage is severe or recurring, the steering gear assembly needs to be replaced to ensure safety. In daily driving, avoid holding the steering wheel in the fully turned position for a long time or turning with excessive force to reduce the pressure on the seals. At the same time, It is best to regularly check the power steering oil level and the condition of the pipelines, and replace the power steering oil every 40,000 to 60,000 kilometres. Preventive maintenance can significantly reduce the risk of oil leakage. If signs of oil leakage are found, It is best to have it handled by professional maintenance personnel as soon as possible to avoid affecting driving safety due to power steering failure.
