• Noisy or inconsistent steering assist
• Binding or rough steering response
• Wear-related steering performance loss

Installation Notes and Tips

• Verify spline count, shaft diameter, and line fitting sizes before installation.
• Inspect hydraulic lines and related steering components for wear before reassembly.
• Because mounting hardware and brackets are not included, reuse or source the correct vehicle-specific hardware as needed.
• Perform a professional alignment after installation.
• Bleed the power steering system thoroughly to remove air from the hydraulic circuit.
