GKNY10028 Hydraulic Pump, steering (SPIDAN OE-Spec Replacement)

The GKNY10028 Hydraulic Pump, steering is a SPIDAN power steering pump listed under our
Power Steering Pump category at
CG Auto Parts Shop. Every listing includes a full manufacturer cross-reference
table so you can confirm fitment by part number before you order.

How It Works

A hydraulic power steering unit  is a belt-driven vane- or roller-type pump that pressurises power steering fluid and delivers it to the steering rack or steering box, where that hydraulic pressure reduces the effort required to turn the wheels. A flow-control and pressure-relief valve within the pump maintains consistent assist across the engine speed range.

Signs You Need a Replacement

A whining noise that varies with engine RPM and worsens at full steering lock, along with stiff or inconsistent steering effort especially at low speed, indicates the component is losing pressure or flow. Air in the system from a low fluid level or a seeping shaft seal makes the steering feel gritty or causes a groan on full lock.

Brand & Manufacturing Authority

This component is manufactured by SPIDAN, a recognised supplier to the automotive aftermarket. The part number GKNY10028 identifies this specific unit in the manufacturer’s own catalog. It is supplied new — not remanufactured — and is backed by our warranty policy.

Material & Construction

Built from cast aluminium or steel housing with a vane- or roller-type rotor assembly, shaft seal, and integral reservoir or remote reservoir connection, matched to the OEM pressure and flow specification for the steering rack fitted. This construction is chosen to match or exceed the OE
specification it replaces under the same load, temperature, and service conditions.

Fitment Confidence

Year-make-model filters alone can miss mid-year production changes that affect fitment. The safest
method is to match the part number stamped on your existing unit against the cross-reference table below. If you can’t locate your existing part number, send your vehicle VIN through our contact page and we’ll confirm before you order.

Product Specifications

Cross-Reference Compatibility Table

Match your existing part number against this table before ordering. All data is drawn directly
from the manufacturer’s own cross-reference documentation.

Installation & Safety Notes

Fill the reservoir with the vehicle-specific fluid type. Bleed the system by cycling the steering lock to lock with the engine off, then running, until the noise clears. Flush the entire circuit if the original pump failed and left metal debris in the system. Always follow your vehicle manufacturer’s torque specifications and service manual procedure. For the engineering standards that govern this part category, see the SAE International steering standards.

Quality Assurance

We verify every listing’s cross-reference data against the manufacturer’s own catalog before
publishing. We sell SPIDAN parts because the brand has a documented track record in the steering
component category. If a part number doesn’t match your vehicle after checking the table above, contact us and we’ll find the correct one.

Choosing the Right Component — A Buyer’s Guide

Shopping for a steering component by part number rather than by vehicle model alone is the most reliable way to avoid a fitment mismatch. A year-make-model filter is a starting point, but the same vehicle model can use different component specifications depending on trim level, engine variant, and production date. The cross-reference table above is built from the manufacturer’s own part-number data, which means the relationship between this part and the vehicle application is confirmed at the component level rather than inferred from model data.

When you receive the new unit, compare it physically against the old part before installation — check overall dimensions, mounting hole positions, and connector orientation. A direct visual comparison catches any discrepancy before time is invested in disassembly. If anything doesn’t match despite the part number confirming correctly, contact us before installing, since we can usually resolve fitment questions the same day.

We source our SPIDAN parts directly through authorised supply channels to ensure you receive the genuine part that the cross-reference table confirms. Aftermarket quality varies enormously by brand; listing the actual manufacturer — rather than a generic “compatible with” label — is how we give you the information needed to make a confident buying decision. The About Us page explains our approach to sourcing and part-number verification in more detail.

After Installation — What to Check

Once the new unit is fitted and torqued to specification, a brief test drive under controlled conditions is the best way to confirm the repair is successful before returning the vehicle to normal use. Listen for any new noises from the affected area at low speed over a rough surface, and confirm that the system behaviour feels correct. For suspension and steering components, a wheel alignment check immediately after installation is strongly recommended, since even a correctly fitted new part can require alignment correction compared to the worn part it replaced. For braking components, a proper bed-in procedure — a series of graduated stops from
road speed — transfers an even layer of friction material and settles the new components before maximum braking loads are applied.

Keep the installation date and part number noted in your service records. This information is
required if a warranty claim becomes necessary, and it makes future parts sourcing straightforward
since you’ll have a confirmed part number on file. Our warranty
policy page specifies the documentation needed to support a claim.
