Steering Pump 101: Types, Failure Symptoms, and How to Replace It Right

What Is a Steering Pump?

The steering pump is a vital part of your vehicle’s power steering system. It generates the hydraulic pressure (or assists electric systems) needed to make steering smooth and responsive, especially at low speeds or when the vehicle is stopped.

Types of Steering Pumps

1. Hydraulic Power Steering Pump (HPS)

Uses a belt-driven pump and hydraulic fluid.
Found in older or heavy-duty vehicles.
Provides a natural steering feel but requires more maintenance.

2. Electric Power Steering Pump (EPS)

Uses an electric motor to generate pressure.
Found in most modern vehicles.
More fuel-efficient and reliable but costlier to repair.

3. Electro-Hydraulic Power Steering (EHPS)

A hybrid system: electrically driven hydraulic pump.
Balances fuel efficiency and strong assist performance.

Common Symptoms of a Failing Steering Pump

If your steering pump is wearing out, you may notice:

Whining or squealing noise when turning the wheel
Stiff or hard steering at low speeds
Fluid leaks near the power steering reservoir or pump
Burning smell caused by friction and fluid loss
Foamy or low power steering fluid

Why Timely Replacement Matters

Ignoring a worn-out steering pump can lead to:

Increased steering effort (especially dangerous at low speeds)
Irregular tire wear
Overheating of the power steering fluid
Damage to the entire steering system

Timely replacement not only ensures safety but also saves money in the long run.

Tips for Choosing the Right Replacement

Match the OEM number to ensure fitment.
Check compatibility with your car’s make, model, and year.
Consider remanufactured options for cost savings.
Buy from reliable suppliers who offer warranty and return support.

Final Thoughts

The steering pump may be out of sight, but it plays a big role in your driving experience. If you hear strange noises or feel extra resistance while turning, don’t wait—inspect your steering system and replace the pump if needed.
