Designed to supply the hydraulic pressure behind your steering assist, the Atlantic Automotive Engineering (AAE) LS430 power steering pump, part number 5596N, is a new unit built as a direct replacement for a failed original pump. It fits the 2001-2006 Lexus LS430. See the Buyer's Guide tab for engine details.
AAE builds these new hydraulic pumps with OE-quality components. Every unit is inspected and tested for OE operation and fitment before it ships.
100% tested: each pump is hydraulically tested under load in the USA before shipment.
Pulley included: arrives with the pulley and a return pipe adapter. The reservoir is not included.
Sensor preinstalled: the sensor is included and already installed on the pump.
No core charge: the pump is sold new, with no core to return.
AAE engineers these pumps to match or surpass OE specifications for performance, fit and function. To help safeguard long life and OE-level operation, AAE advises flushing the steering system and refilling it with an OE-approved power steering fluid at installation. AAE also highly recommends replacing the steering fluid reservoir along with the pump, because a clogged reservoir can starve the replacement pump of fluid.

Frequently Asked Questions
Is this a Lexus LS430 power steering pump?
Yes. AAE 5596N is a direct replacement for the power steering pump on the 2001-2006 Lexus LS430.
Does it come with a reservoir or pulley?

What does a power steering pump do?
The engine belt drives the pump, which pressurizes power steering fluid and sends it to the steering gear to provide hydraulic steering assist.
What are signs a power steering pump may need replacing?
Common signs include a whining noise when turning, steering that feels heavy or stiff, and fluid leaking at the pump. Diagnose the cause first, because other steering components can cause similar symptoms.
