Used Steering Pump for Medium-Duty Trucks
Power steering pumps — and on hydro-boost trucks, the pump that also powers your brakes.
- Used OEM part
- Tested before shipping
- 30-day warranty
- Ships to the lower 48
- Refundable core

On most of these trucks the power steering pump does two jobs: it steers, and through the hydro-boost unit it powers the brakes. When it whines, cavitates or loses pressure hot, you get heavy steering and a hard pedal at the same time. It’s the single most misdiagnosed part in the steering-and-brake system — and one of the cheapest to replace correctly.
We supply used OEM pumps from running donor trucks, checked for pressure and noise, with the correct pulley and reservoir arrangement for your engine. A refundable core charge may apply; it’s stated on your quote.
Signs your steering pump has failed
- Whine or groan that rises with engine RPM, worse cold or at full lock
- Heavy steering and a hard brake pedal together
- Foamy or dark fluid; reservoir level that fluctuates
- Assist drops out at idle and returns with throttle
- Leaks at the pump shaft seal or reservoir seams
- Belt squeal from a seized or dragging pump pulley
Before you order
- Send your VIN and engine — pump mounting, pulley type and reservoir (integral or remote) change by engine and year.
- Replace the fluid completely and flush the lines; debris from the old pump ruins a replacement in weeks.
- Check for a collapsing suction hose and a clogged return filter on trucks that have one.
- Bleed the hydro-boost per the service manual after installation; air in the booster gives a hard pedal that looks like a bad pump.

Is a used Steering Pump tested before it ships?
Yes. Every steering pump we sell is pulled from a running donor truck, inspected and tested before it ships.
How do I get a quote for a used Steering Pump?
Use the form on this page or call us. Share your truck and VIN and we confirm exact fitment, then call you back with a price in about 30 seconds during business hours — or email it if we can’t reach you.
Is a used Steering Pump covered by a warranty?
Yes, we stand behind this steering pump with our warranty. Exact terms are confirmed on your quote.
Do you ship a used Steering Pump nationwide?
Yes — we ship to all 48 contiguous states with tracked delivery. Most parts arrive in 3–7 business days; engines, transmissions and axles ship freight and typically arrive in 5–10.
Why does my brake pedal get hard when the steering gets heavy?
Hydro-boost. The brake booster runs on power steering pressure, so a failing pump takes out both. Fix the pump first; the pedal usually comes back with it.
Is the pulley and reservoir included?
Where the donor had them. Tell us whether you need the pulley and reservoir and we’ll match your setup so it bolts on the first time.
Is there a core charge on this Steering Pump?
This steering pump may carry a refundable core charge, returned when your old unit is sent back within 30 days. Any core charge is stated clearly on your quote.
