Replacement RA28950001 Power Steering Rack and Pinion Assembly with Inner Tie Rod Ends

The Replacement RA28950001 is a hydraulic power steering rack and pinion assembly designed as a direct-fit replacement for the 2007–2013 Acura MDX. This unit includes pre-installed inner tie rod ends, simplifying the installation process and ensuring a complete, ready-to-install assembly. It replaces OEM part numbers 53601STXA01 and 53601STXA02.

The rack and pinion is the core component of the MDX's hydraulic power steering system. It converts rotational steering wheel input into the lateral movement required to turn the front wheels, using a hydraulic power-assist circuit to reduce driver effort. Over time, internal seals can wear, leading to symptoms such as fluid leaks, stiff steering, loose or wandering handling, or a pulling sensation while driving — all signs that rack replacement may be necessary.

Key Features:

• Direct-fit replacement for 2007–2013 Acura MDX (2nd Generation)
• Hydraulic power-assist steering system design
• Includes inner tie rod ends for a complete assembly
• Replaces OEM part numbers: 53601STXA01, 53601STXA02
• Restores precise steering feel and eliminates fluid leaks caused by worn seals

Installation Note: A professional wheel alignment is required after installation, as replacing the steering rack and tie rods directly affects front wheel toe angle. Using genuine Honda/Acura power steering fluid is strongly recommended to ensure proper system performance and seal longevity.
