Push hydraulic fluid to the steering gear and keep power-assist responsive with the CARDONE Remanufactured Power Steering Pump 21-5258. This reman unit installs as a direct-fit replacement for the 1999-2003 Lexus RX300 and the 2001-2003 Toyota Highlander, engineered to meet or exceed O.E. performance. Because it is remanufactured, original designs are scrutinized for potential improvement and, where applicable, design upgrades are applied for a more durable part than the original.

  • Triple-tested critical parts: campacs, spool valves and other critical components are triple-tested to verify reliable function.
  • Leak-resistant seals: built with 100% new O-rings and premium-grade HNBR seals, which do not break down at high temperatures like conventional seal material.
  • Precision shafts & valves: shafts are surfaced to precise specifications to reduce premature seal wear and extend pump life, and each unit ships with a 100% tested and calibrated pressure relief valve.
  • Computer-tested assembly: the final pump is computer-tested for pressure, bypass, fluid flow, valve operation, steering effort and noise.

The remanufacturing process is earth-friendly, cutting the energy and raw material needed versus a new part by roughly 80%. See the Buyer's Guide tab to confirm the engine for your vehicle.

This part cross-references / interchanges with the following part numbers:

Frequently Asked Questions

What does this power steering pump do?

It pressurizes hydraulic fluid and delivers it to the steering gear to provide power-steering assist, reducing the effort needed to turn the wheel.

Which vehicles does the 21-5258 fit?

It is a direct-fit replacement for the 1999-2003 Lexus RX300 and the 2001-2003 Toyota Highlander. Check the Buyer's Guide tab to confirm the engine for your vehicle.

Is this a new or remanufactured pump?

It is a CARDONE remanufactured unit built to meet or exceed O.E. performance, with design upgrades applied where applicable for a more durable part than the original.

What seals are used in this pump?

It is assembled with 100% new O-rings and premium-grade HNBR seals. HNBR does not break down at high temperatures the way conventional seal material can, helping resist leaks.

What are signs my power steering pump may need replacing?

Whining or groaning noise when turning, hard or inconsistent steering effort, and fluid leaks can indicate a failing pump. Diagnose the cause before replacing, as other components can produce similar symptoms.
