Supply the pressurized fluid your steering system relies on for hydraulic assist with the Atlantic Automotive Engineering (AAE) 50108N, a new Toyota 4Runner power steering pump that is 100% tested in the USA before it ships. AAE builds it as a direct replacement for a failed original unit on the 2010-2024 Toyota 4Runner. See the Buyer's Guide tab for engine details.
AAE builds these pumps with OE-quality components. Every unit is inspected and tested to confirm OE operation and fitment, and AAE designs its pumps to match or surpass OE requirements for performance, fit and function.
- Tested under load: each unit is 100% hydraulically tested under load in the USA before shipment.
- Included components: the pulley is included, a sensor comes included and preinstalled, and a return pipe adapter is supplied.
- Reservoir not included: AAE highly recommends replacing the steering fluid reservoir along with the pump, because a clogged reservoir can starve the replacement pump.
- No core charge: AAE new power steering pumps are sold without one.
To help protect long life and OE performance, AAE advises flushing the steering system and refilling it with an OE-approved power steering fluid when you install the pump. Signs a 4Runner power steering pump may need replacing include whining or groaning while turning, heavy or stiff steering, and fluid leaking at the pump. Diagnose the cause first, because hoses, fluid level or the steering gear can produce similar symptoms.
