What are the reasons for the sudden loss of power steering in a classic Focus?
2 Answers
Classic Focus sudden loss of power steering may be caused by power steering booster leakage, lack of power steering fluid, or damage to the power steering pump. Power steering booster leakage: Caused by aging seals. Rubber seals on vehicles, over time and influenced by temperature fluctuations, lose plasticizers. Seals that lose plasticizers shrink and harden, losing their sealing properties. The most direct solution to this issue currently is to replace the seals. Lack of power steering fluid: The consumption of power steering fluid is a normal phenomenon. Insufficient power steering fluid can lead to difficulty in steering. Power steering is a new technology in automobiles designed to increase comfort by automatically providing steering force when the driver turns the wheel, thereby reducing the driver's steering effort. Power steering fluid is a medium oil added to the power steering system, serving to transmit steering force and provide cushioning. Power steering pump damage: Increased noise during steering. Steering wheel hesitation during turning. Noticeably heavier steering wheel when turning. Inaccurate steering direction during turning.
My classic Focus also experienced sudden heavy steering before, which was particularly dangerous on the highway—I almost hit the guardrail. I immediately turned on the hazard lights and slowly pulled over. After stopping, I popped the hood to check. The power steering fluid reservoir was empty, clearly indicating a leak that prevented the power steering pump from working. Older Focus models often have aging rubber hoses that crack, especially near the high-pressure hose connections around the steering gear, which are prone to leaks. Additionally, if the power steering pump belt is loose or broken, you can lose power assist instantly—I later made sure to check the belt for cracks. After towing it to the repair shop, they found the power steering pump itself was worn and leaking; replacing it fixed the issue. If you encounter this situation, don’t force it—the steering wheel becomes dangerously stiff, and you could end up in a serious accident.
