Power Steering Pumps
The power steering pump provides the necessary hydraulic pressure to assist with steering. A quality steering pump significantly enhances driving precision, reduces steering effort, and improves overall vehicle safety.
We understand the nuances of selecting the right replacement power steering pump, especially when vehicle modifications are made (such as larger tires). We offer OEM replacement pumps and complete pump kits that adapt a superior, higher-flow pump to fit your vehicle. In addition to selling new pumps, we also offer a pump rebuilding service for specific OEM pumps. Call to see if yours is on our list of rebuildable pumps.
Frequently Asked Questions About Power Steering Pumps
What does a power steering pump do?
The steering pump pressurizes hydraulic fluid, delivers fluid to the steering gear, and reduces the physical effort needed to turn the wheel.
How do I know if my pump needs replacement?
The most common signs include whining or groaning noises when you turn the wheel, needing more effort when steering, fluid leaks near the pump, or inconsistent steering responsiveness.
How do I choose the correct power steering pump for my vehicle?
You should consult your vehicle’s manual for specifications and consider factors like pressure ratings, pulley compatibility, reservoir style, and fitment types.
Do gearbox pumps need pressure and flow settings that are different from those for rack and pinion?
Yes. Pumps for a gearbox are usually set at higher settings than a rack and pinion.
Does tire size have any effect on the steering pump settings?
Yes. Larger tires can dictate higher pressure and flow settings.
Can air in the steering system make a pump noisy?
Yes. Air in the system will make a steering pump noisy. Air is introduced from improper bleeding or a leak anywhere in the system. We have even seen instances where a hose will “suck air” without having a noticeable leak. Gearboxes that wear out or hydro boosts can also have internal leaks that can introduce air into the system.
Can the reservoir style make my pump noisy?
Yes. Reservoir design can lead to a noisy pump. Improper baffling, lack of baffles, and improper return line placement can all contribute to this. We receive calls daily from customers using aftermarket reservoirs, which can make their systems noisy. The Lee Power Steering reservoirs have a proprietary internal design that uses a series of baffles and a fluid-slowing device to keep the fluid still. This also results in a much cooler system.
