What could indicate a defective power steering system besides noise?

A defective power steering system can manifest in various ways beyond just producing noise. One key indication is difficulty in steering, particularly at low speeds. This is significant because power steering systems are especially designed to ease the steering effort, making it more manageable for drivers to turn the steering wheel. At low speeds, like when parking or maneuvering in tight spaces, the assist provided by the power steering system is crucial. If you experience increased resistance or a heavy feeling in the steering wheel, it suggests that the power steering system is failing to assist adequately, signaling a possible defect.

While difficulties in steering at high speeds can occur, they are often less noticeable compared to low-speed scenarios where steering effort is critical. Regarding increased fuel consumption, that is usually a broader factor associated with overall vehicle efficiency and may not directly indicate a power steering issue. Similarly, brake failure is a separate concern that does not correlate with power steering system functionality. Understanding these nuances helps identify and address power steering defects effectively.
