Power Steering Maintenance

Most drivers under 40 have never experienced a vehicle without power steering. Today’s vehicles rely on one of three power assist designs:

• Hydraulic power steering pumps, typically driven by the serpentine belt
• Electric-hydraulic pumps, which combine fluid systems with electric motors
• Fully electric power steering (EPS) systems, where an electric motor directly assists steering input

While these systems make steering effortless, they are not maintenance-free.

Why Power Steering Fluid Matters

Hydraulic and electric-hydraulic systems rely on fluid to transmit pressure and lubricate internal components. Over time, that fluid:

• Absorbs moisture
• Collects metal particles and contaminants
• Loses its ability to protect seals and internal parts

If left unchanged, contaminated fluid accelerates wear, leading to leaks, noisy pumps, or total system failure.

Preventive Maintenance That Pays Off

A periodic power steering fluid service removes old, contaminated fluid and replaces it with clean fluid designed to protect pumps, hoses, and seals. This simple service can significantly delay expensive repairs.

👉 Best practice: Ask your service advisor at DJ’S Repair Service about the manufacturer’s recommended power steering fluid change interval for your vehicle.

Mechanical Steering Components: The Parts That Actually Turn the Wheels

Power assist helps you steer—but mechanical components do the real work. These parts include:

• Tie rods
• Ball joints
• Steering racks or gearboxes
• Control arms and related joints

Can These Parts Be Maintained?

Some steering components are equipped with grease fittings. During a lube, oil, and filter service, your technician will lubricate these parts to reduce friction and slow wear.

Beyond lubrication, maintenance becomes more about early detection.

Warning Signs of Steering Wear

Keep an eye out for:

• Loose or wandering steering
• Steering wheel vibration
• Clunking or knocking noises when turning
• Uneven or rapid tire wear



These symptoms often indicate worn or failing steering components that should be addressed promptly.

Impact Damage: The Hidden Threat to Your Steering System

Not all steering problems come from normal wear. Potholes, curbs, and road debris can bend or damage steering parts instantly. Even minor damage can throw your alignment off and place added stress on connected components.

Ignoring this kind of damage often triggers a chain reaction—where one bad part accelerates failure in others. Early repair is almost always cheaper than waiting.

Simple Steering Maintenance = Long-Term Savings

Steering system care doesn’t have to be complicated:

✔ Replace power steering fluid at recommended intervals

✔ Lubricate serviceable steering components

✔ Address worn or damaged parts immediately

Staying proactive helps maintain safe handling, protects your tires, and saves money over the life of your vehicle.
