Product Details
This Maval New Power Steering Pump is intended for Lexus LS400 models from 1998 through 2000. The application notes call out elevated underhood temperatures and fluid varnishing within the steering system, hydraulic lines, and pump. For that reason, Maval recommends replacing the steering system as a complete assembly to reduce contamination-related repeat failures. The 96307MN is also listed with an electronic solenoid included when the unit is equipped with one.
This part cross-references Cardone Reman 21-5143 for the same application. The 96307MN is a direct-fit steering pump solution for Lexus LS400 owners addressing noise, pressure loss, or fluid contamination concerns.
Common Issues This Part Can Address
- Hard or inconsistent steering effort
- Whining or pump noise during steering operation
- Loss of hydraulic pressure in the power steering system
- Fluid varnishing and contamination in the steering circuit
- Wear-related pump performance decline on Lexus LS400 models
Installation Notes and Tips
Fits 1998-2000 Lexus LS400, N/A. Review the instruction sheet packet 656080 before installation. Because the application notes reference contamination throughout the hydraulic system, inspect the steering gear, hoses, and related components before installing the new pump. Confirm whether the vehicle is equipped with an electronic solenoid and transfer any required component as specified by the application.
Quality Assurance
Maval specifies high-temperature seals for this New Power Steering Pump line to address the heat-related conditions noted in the application. Part number 96307MN is listed for Lexus LS400 fitment and cross-references Atlantic Automotive Engineering 5366 and Cardone Reman 21-5143.

| 2000 | Lexus | LS400 | N/A | The operating temperature within the engine compartment exceeds the tolerance of the OE seals throughout the hydraulic system. Over time this results in the hydraulic fluid "varnishing" within the steering unit, hydraulic lines and pump. This "varnishing" results in contamination throughout the system. Maval utilizes high temperature seals and recommends a complete replacement of the steering system in order to avoid contamination related problems. Refer to instruction sheet packet 656080.
