Power Steering Pump for 2005-2019 Nissan Frontier & More - CARDONE Reman 21-5451

Keep steering light and responsive with the A1 CARDONE Remanufactured Power Steering Pump (P/N 21-5451, also written 215451). This pump pressurizes hydraulic fluid to supply the assist that reduces the effort needed to turn the steering wheel. It's a direct-fit replacement for the 2005-2019 Nissan Frontier, 2005-2012 Nissan Pathfinder, 2005-2015 Nissan Xterra, and 2009-2012 Suzuki Equator — see the Buyer's Guide tab for full engine-level details.

Remanufactured from an original-equipment core, each unit is scrutinized for potential improvement, with design upgrades applied where applicable for a more durable part, then verified through a hydraulic efficiency test.

• Triple-tested internals: all critical components (campacs, spool valves, and more) are triple-tested for reliability.
• HNBR seals: built with 100% new O-rings and premium-grade HNBR seals that resist breakdown at high temperatures, helping prevent leaks.
• Precision shafts: shafts are surfaced to precise specifications to reduce premature seal wear and extend pump life.
• Fully tested: supplied with 100% tested and calibrated pressure relief valves, and final assembly is computer-tested for pressure, bypass, fluid flow, valve operation, steering effort, and noise.

Signs the original pump may need replacing include a whine or groan when turning, heavier-than-normal steering effort, or fluid leaks.
