Why Does Car Steering Wheel Become Harder & Stiffer?

Low Power Steering Fluid

Having low power steering fluid is a common cause of hard steering. When the fluid level drops, the steering system loses the hydraulic pressure needed to function smoothly. This lack of pressure makes it difficult to turn the steering wheel, which may result in a hard power steering problem.

The issue often arises from leaks or neglecting to top off the fluid, resulting in decreased steering efficiency.

Thick Power Steering Fluid

Thick power steering fluid can also cause a hard power steering problem. Over time, the fluid can thicken due to contamination or degradation and lose its proper consistency. This thickened fluid increases resistance within the steering system, and makes it harder for the steering system to function correctly.

The buildup of debris and deterioration of fluid quality can impact the ease of steering, and lead to a steering hard problem.

Power Steering Pump Malfunctioning

Another cause of hard steering is a malfunctioning power steering pump. The pump is responsible for circulating the power steering fluid throughout the system. When the pump fails or operates inefficiently, it cannot circulate fluid effectively and reduces the hydraulic pressure.

This leads to a hard power steering problem and makes it difficult to turn the steering wheel. Issues with the pump can stem from mechanical failures, wear and tear or inadequate maintenance.

Damaged Steering Rack

A damaged steering rack can lead to a steering hard problem. The steering rack translates the rotational movement of the steering wheel into the linear motion needed to turn the wheels.

Over time, wear and tear or physical damage can cause the rack to become less responsive or even jam. This degradation makes it increasingly difficult to turn the steering wheel, impairing the vehicle's handling and control.

Serpentine Belt Damage or Slippage

Damage or slippage of the serpentine belt can cause a hard steering problem. The serpentine belt drives the power steering pump, and any issues with the belt can disrupt this function.

If the belt is worn, damaged or slipping, it can cause a reduction in the power steering pump's performance. This makes it difficult to turn steering wheel and leads to a hard steering wheel as the hydraulic pressure needed for smooth steering is compromised.

Inadequate Tyre Pressure

Inadequate tyre pressure is a common cause of hard steering. Both overinflated and underinflated tyres can make it difficult to turn the steering wheel, leading to a hard power steering problem. Improper tyre pressure increases the effort required to steer, eventually leading to a hard power steering problem.

Inaccurate Wheel Alignment

Inaccurate wheel alignment can cause a steering hard problem. When wheels are misaligned, they put extra strain on the steering system and make it difficult to turn the steering wheel.

This misalignment can result from hitting potholes, curbs or regular wear and tear. It compromises the vehicle's handling and steering response, leading to a harder steering experience.

Irregular Car Servicing

Irregular car servicing can lead to various issues, including a hard steering problem. Neglecting regular maintenance can cause steering system parts to wear out or malfunction.

Over time, the lack of servicing can result in the buildup of problems that make it difficult to turn the steering wheel. Consistent and thorough servicing ensures all parts are in good working condition to prevent hard steering problems.

Steering Column Issue

Problems with the steering column can also cause hard steering. The steering column creates the connection between the steering wheel and the steering mechanism. If the column is damaged, worn or misaligned, it can create resistance and make it difficult to turn the steering wheel.

This issue can happen due to various reasons, such as physical damage, wear over time or improper installation. All such problems eventually lead to a hard steering wheel.

Front Suspension Problems

Front suspension problems can contribute to a steering hard problem. The suspension system supports the vehicle's weight and absorbs shocks from the road.

If components of the front suspension system, such as struts, shocks or control arms are damaged or worn, it can affect the steering system. This can make it difficult to turn the steering wheel, leading to a hard steering problem.

Regularly Check Power Steering Fluid: Ensure the power steering fluid is at the correct level and replace it periodically to maintain its proper viscosity.

Inspect the Power Steering Pump: Regularly check the power steering pump for any signs of malfunction and repair or replace it as needed.

Monitor Steering Rack Condition: Regularly inspect the steering rack for any signs of damage and promptly address issues.

Maintain the Serpentine Belt: Regularly inspect the serpentine belt for wear or damage and replace it if necessary to ensure it drives the power steering pump efficiently.

Check Tyre Pressure: Monitor and maintain the correct tyre pressure regularly to prevent strain on the steering system.

Ensure Proper Wheel Alignment: Schedule regular wheel alignment checks and adjustments to avoid extra strain on the steering system.

Regular Car Servicing: Keep up with regular car servicing to ensure all steering system components are in good condition.

Use Recommended Power Steering Fluid: Always use the power steering fluid recommended by the vehicle manufacturer to ensure optimal steering system performance.

Check Steering Column Issue: Inspect the steering column for any signs of damage, wear, or misalignment. Address any issues promptly to avoid added resistance and ensure smooth steering.

Check front Suspension Problems: Check the front suspension components, such as struts, shocks and control arms, for wear or damage. Repair or replace faulty parts to maintain proper steering function and vehicle stability.

Is it safe to drive with hard steering?

Driving with hard steering can be dangerous as it impairs your ability to control the vehicle effectively. Addressing the underlying causes promptly is essential to ensure safe driving conditions.

Can weather conditions affect steering hardness?

Extreme weather conditions, such as very cold temperatures, can cause power steering fluid to thicken and lead to harder steering. Regular maintenance and using the appropriate type of power steering fluid can help mitigate this issue.

What should I do if I hear unusual noises while turning the steering wheel?

Unusual noises while turning the steering wheel can indicate issues such as low power steering fluid, a malfunctioning power steering pump, or a damaged steering rack. It is advisable to have the steering system inspected by a professional mechanic to diagnose and fix the problem.

How do I know if the power steering of my car is failing?

Signs of a failing power steering pump include whining or groaning noises when turning the steering wheel, a stiff or hard steering wheel, and fluid leaks. If you notice any of these symptoms, it is important to have the pump inspected and repaired or replaced.
