In this review the focus is on the Power Steering Pump with Pulley 21-5442, a direct replacement aimed at owners of specific Honda Pilot, Odyssey and MDX model years. The bottom line: this pump is for drivers who need a reliable OE-replacement that restores steering smoothness and reduces whining. It installs in place of the listed part numbers and is best when a failing pump is the likely cause of stiffness, slow steering response, or unusual noise; the reviewer found it delivers solid function and clear compatibility guidance.

Key Features

• OE replacement: Replaces part numbers 21-5442, 96-5442 and multiple 56110-... references, ensuring fit where those OE numbers apply.
• Vehicle compatibility: Compatible with 2005-2008 Pilot, 2005-2010 Odyssey and 2007-2013 MDX models when matched by year and part number.
• Noise control: Designed to quiet whining and reduce unusual noise when the pump is the source of the problem.
• Steering feel: Restores smoother wheel movement and quicker steering response when a defective pump causes stiffness or lag.
• Installation note: The listing advises professional installation to avoid damage during setup and testing, which helps ensure reliable operation.

Who It's For

This pump is suited to DIY mechanics or shops replacing a failed power steering pump on a compatible Honda Pilot, Odyssey or MDX where the original part number matches the listed references. It is particularly useful for owners experiencing whining, rough steering, or stiffness and who want an OE-form replacement rather than a generic or rebuilt item.

Drivers with other makes or model years outside the listed ranges should look elsewhere, and anyone uncomfortable with hydraulic system work should plan for professional installation because correct mounting, fluid bleeding and testing are important for long life and safety.
