Application
Fits military jeeps with Dana 25 or 27 front axle and Dana 23 or 27 rear axle, as used in the vehicles from the categories in which this product is included. For front axle: Dana 25/27 with standard open differential. For rear axle: Dana 23/27 configuration. Always verify the axle model on your vehicle (usually stamped on the differential housing) before ordering.
Installation notes
The differential case must be fitted with correct carrier bearing preload and backlash adjustment. Use new carrier bearings and shims when replacing. The ring gear bolt holes must be clean and free from damage. Ensure correct gear adjustment (backlash 0.004"-0.008") according to TM specifications. Professional installation recommended for optimal service life.
Compatibility
Only for standard open differentials — NOT compatible with limited slip or diff-lock designs. Dana 25 and Dana 27 front axles use the same spider gear sets (10 teeth). Note differences between early and late production versions regarding bearing specifications. Check the number of bolt holes and ribs on your original case before ordering.
Historical context
The Dana/Spicer differentials in WWII jeeps and early CJ models were robust, reliable constructions that proved their performance under extreme conditions. These components form the heart of the drivetrain and were essential for the off-road capabilities of these iconic vehicles.
