Detailed Description

The 64378N rack and pinion assembly is intended for drivers needing a direct hydraulic steering gear replacement on compatible Ford, Lincoln, and Mercury platforms. It is a complete rack and pinion unit for applications that do not use electronic steering and, in listed notes, do not use outer tie rod ends. This makes it a focused solution for restoring steering response, reducing play, and addressing hydraulic steering wear in the original system.

This part cross-references OE-style numbers such as 8A5Z3504C and BG1Z3504A for the same application.
