Pinion Shaft Diameter Measurement

4 of 13
The pinion shaft diameter is similar to the Dana 60, but the length is shorter than the Dana styles, which helps in the pinion angle department. The head of the pinion in this 4.56 ratio example is the same as the Dana 60 and bigger than the 44. The bearing journals are about the same size as the 60, but special bearings are used for better load capacity than the stock 8.8 bearings.
