Power steering loss after gear replacement

<p>After replacing the steering gear, some drivers experience a loss of power steering assistance, making steering feel heavy and unresponsive. This issue often presents immediately after the replacement or shortly thereafter. Key symptoms include increased steering effort, especially at low speeds, and a lack of hydraulic or electronic steering assistance. Diagnosing this issue involves checking for proper installation, fluid levels, and potential electronic malfunctions.</p>

<ul><li><b>Air in the System:</b> Air pockets trapped in the hydraulic lines can impede fluid flow, causing the steering assistance to diminish. Bleeding the system may resolve this.</li><li><b>Incorrect Steering Gear Installation:</b> Misalignment or improper connection of the steering gear can disrupt the hydraulic or electronic systems, leading to loss of power assistance.</li><li><b>Faulty Power Steering Pump:</b> A failing pump may not provide adequate pressure, especially noticeable after the system has been disturbed during gear replacement.</li><li><b>Electronic Control Unit (ECU) Malfunction:</b> In vehicles with electronic power steering, an ECU error or reset may be required post-installation to restore proper function.</li><li><b>Low Power Steering Fluid Level:</b> Insufficient fluid due to leaks or improper filling during installation can cause a lack of hydraulic assistance.</li><li><b>Damaged or Pinched Hydraulic Lines:</b> Hydraulic lines that are pinched or damaged during the replacement process can restrict fluid flow, affecting steering performance.</li><li><b>Incorrect Steering Gear Calibration:</b> Some modern vehicles require recalibration of the steering gear or sensors to ensure proper functionality post-replacement.</li></ul>
