Shop now for Differential Bearings and Pinion Bearings to fit 1961-1964 Jeep CJ-3B with Dana-Spicer Model 27 closed knuckle front axles.
Differential Bearings and Bearing Cups specific to 1961-1964 Dana 27 Front Axles are Listed Below. The 1961 IHC Scout was the first production 4x4 to use the new Dana 27F front axle when it was introduced in 1960 as a 1961 model year vehicle. Jeep started using the Dana 27F during the 1961 model year for CJ-3B (serial numbers 57348-69426 to 57348-75400) before reverting back to the Model 25. From 1962 to possibly as late as 1965, Jeep concurrently used both the Model 25 and Model 27F axles for CJ. See the chart in the Axle Identification Section to identify a Jeep Dana 27 front axle by bearing cup sizes. NOTE: in Jeep Factory Parts Books, the Dana-Spicer Model 27F is referred to as the Model 27.
