★ Authentic used steering component from the WWII period. Given the critical safety role of this component, we recommend having this part inspected and rebuilt as necessary with new bearings (639104, 639102) and seals before installation.
Application
Fits 1941-1945 Willys MB, 1941-1945 Ford GPW, and early 1946-1948 CJ-2A up to serial number 178631. Note: late CJ-2A models (after serial number 178631) and later models often used the longer 41.5 inch version (657693). Always measure the existing assembly before ordering.
Installation notes
This assembly is the heart of the steering system and requires correct installation. Before installation, check the condition of the worm gear teeth, the tube for cracks or bent sections, and replace bearings and seals. The assembly must be fitted with correctly adjusted bearings (no play, not too tight). Fill the steering gear box with the correct gear oil after installation. Test the steering system thoroughly before operating the jeep.
Compatibility
NOT compatible with: late CJ-2A (after serial number 178631), CJ-3A, CJ-3B, CJ-5, M38, M38A1 — these use the longer 41.5 inch version. The difference lies in the length: early models = 40.5 inches, late models = 41.5 inches. Always measure the existing assembly.
Historical context
The Ross-type steering gear box was used during WWII on all Willys MB and Ford GPW jeeps. The robust worm-and-sector system proved its reliability under extreme combat conditions from North Africa to Europe.
