Features
- Cone (inner ring) and cup (outer ring) as complete set
- Original bearing type for military vehicles and early CJ models
- Suitable for differential and pinion configurations
- Withstands heavy radial and axial loads
- Meets original specifications
★ Industrial standard tapered roller bearing to original specifications. Cone and cup must always be replaced together for optimum reliability and service life.
Installation notes
The cone and cup must always be replaced simultaneously. Assembly is done in pairs opposite each other on the pinion shaft. Correct preload setting and adjustment with shims is essential for quiet and reliable differential operation.
Compatibility
Fits Dana 25 front axles (MB, GPW, early CJ), Dana 41 and Dana 44 rear axles (CJ2A, CJ3A, M38, M38A1, CJ3B). Note: this is the inner pinion bearing — an outer pinion bearing is also required for a complete overhaul.
Historical context
Dana axles were used from 1941 onwards in military Jeeps and civilian CJ models. The tapered roller bearing design was standard for heavy-duty applications due to its capacity to absorb both radial and axial forces.
