Specifications and Applications
All Dana 60 housings are marked with a "Bill of Materials" number and a date code (Figure 2). BoM numbers are found on the back of the right axle tube, 2-3 inches outboard of the center section. All Dana 60 differentials are also marked with a date code. The 'font' for these stampings is a sans serif style and the characters are about 1/8" high. Particularly for the axle tubes, the stampings are faint, so it is important to clean the area well and to visualize them in good light. The BoM number is a 6-digit number with a one or two digit suffix separated by a dash: XXXXXX- X. Date codes are found on both housing and differential and are formatted MM DD Y. Date codes are found inboard of the BoM number on the housing, and on the side of the cylindrical part of the differential. The year code on housings is always one digit and on differentials can be two digits. Housing date codes are followed by a letter (A, B, or C) which may indicate the work shift or factory line. Some differential stampings also show this letter suffix. Zeros are not used in month and day codes. Wide variation in spacing of the components of the date code is seen, and it is not unheard of to see two date codes stamped into a housing, one above the other. These two date codes are usually within a few weeks of one another.

Axle shaft dimensions vary in Dana 60 axles. Dimensions of semi- floating (passenger car type) axles shafts are shown below. Shaft lengths are measured from the outer flange face to the inboard end of the shaft. Note that the right axle shaft is always shorter than the left, so unlike the Chrysler 8 3/4" axle, Dana 60 axle shafts will not interchange side-to-side.
