Lack of Proper Fluid Maintenance

• Over time, power steering fluid can become contaminated with dirt and debris, which can clog and damage the power steering pump and other components.
• Using the incorrect type of power steering fluid can also lead to accelerated wear and eventual failure of the system.
• Low fluid levels can cause the pump to overheat and fail. Regularly checking and maintaining the appropriate fluid levels is crucial.

Power Steering Pump Issues

• The power steering pump itself can fail due to age, wear, or contamination within the fluid system.
• A common symptom of a failing pump is a whining or groaning noise when turning the steering wheel, which indicates that the pump is struggling to function properly.
• Sustained driving with a failing pump can lead to complete loss of power-assisted steering.

Hoses and Lines

• Leaking or damaged hoses and lines can lead to a loss of hydraulic pressure, which is essential for the power steering system to function correctly.
• Hoses can deteriorate over time due to exposure to heat and chemicals, leading to cracks, splits, or burst lines.
• Regular inspections for leaks or damaged lines can help prevent steering failure.

Steering Rack and Pinion Assembly

• Wear and tear on the steering rack and pinion assembly can result in loss of hydraulic pressure and steering assist.
• Internal seals within the rack can deteriorate, causing fluid leaks and reduced effectiveness of the power steering system.
• A failing rack and pinion can cause symptoms such as uneven steering effort, slack in the steering, and unusual noises during turning.

Electrical Issues and Sensors

• In models equipped with electronic power steering (EPS), electrical issues such as faulty sensors or wiring problems can lead to intermittent or complete failure of the power steering system.
• Diagnosing electrical issues often requires specialized equipment and expertise, as it involves scanning for error codes and troubleshooting the electrical components.

Physical Damage

• Physical damage from an accident or impact can affect various components of the power steering system, leading to leaks, misalignment, or total failure.
• It is important to visually inspect the power steering components after any significant impact to ensure they are intact and functioning correctly.
