Application
Suitable for vehicles with Dana 25 front axle (MB, GPW, CJ-2A, CJ-3A, CJ-3B, M38, M38A1), Dana 27 rear axle (MB, GPW early production), Dana 41 rear axle (CJ-2A) and Dana 44 rear axle (CJ-3A, CJ-3B, M38, M38A1). Fits front and rear axles using shims for differential carrier bearing adjustment.
Installation notes
Requires specialised tools: case spreader, bearing puller, dial gauge on magnetic base. Bearings must be fitted and removed multiple times during adjustment process. Shims are placed on outside of carrier bearings between bearing and axle housing. Correct preload is critical — removing shims increases preload, adding shims decreases preload. Professional installation strongly recommended.
Compatibility
Specific to Dana axles with shimmable differential carrier bearings. Not applicable to later axle models using other adjustment systems. Shim thickness varies per individual axle — always check preload with inch-pound torque wrench and backlash with dial gauge. Typically shims are required in thicknesses between 0.003" and 0.030".
Historical context
Adjusting differential carrier bearings with shims was standard practice for Dana/Spicer axles from the 1940s to 1960s. Correct adjustment was crucial for reliable operation under severe military conditions.
