Product Details

Atlantic Automotive Enterprises part number 5175N is a new hydraulic power steering pump engineered for OE-style operation and fitment. It is built for the Lexus LS400 and is intended for drivers replacing a worn or noisy pump, correcting steering assist loss, or addressing fluid leakage at the pump assembly. This part cross-references 4432050010 and 4432050020 for the same application.

The AAE New Power Steering Pump line focuses on application-specific hydraulic replacements that are tested before leaving the USA. For Lexus LS400 service, 5175N provides the pump body with reservoir already installed, while the pulley is not included. Use OE-approved power steering fluid and flush the steering system during service to help maintain pump life and steering performance.

Common Reasons for Replacement

• Whining or groaning from the power steering pump
• Reduced steering assist or heavy steering effort
• Fluid leaks from the pump or reservoir assembly
• Contaminated steering fluid from a failing hydraulic system
• Premature wear from an aging or damaged pump shaft

Installation Notes

Compatible with 1990-1997 Lexus LS400, N/A. Verify pulley reuse requirements before installation, since this pump is supplied without a pulley. Flush the steering system thoroughly and refill with an OE-approved power steering fluid to protect the new pump and maintain proper hydraulic operation.

Quality Assurance

Each AAE power steering pump is inspected and 100% hydraulically tested under load in the USA to confirm operation and fitment. Part number 5175N includes a 24-month/24,000-mile warranty.
