Always buy OEM! Lexus power steering pumps are built with high-precision internal vanes and bearings designed to last hundreds of thousands of miles. Aftermarket "new" pumps often use inferior seals that can fail prematurely under the high heat of the 4.3L V8 engine bay. Furthermore, original Japan-made pumps are balanced to eliminate hydraulic pulsations that can be felt through the steering wheel. By installing an original part, you protect your steering rack and alternator from damage caused by leaks or incorrect pressure.
