    I know what a dana 60, 70, 44 and the differences are, but why were the numbers 60, 70 and 44 assigned to them. Is there meaning behind the numbers?

    They're model numbers.

    I think the model number may correlate to the official weight capacity of the axle, but I can't back this up. e.g. dana 44 = 4,400# cap, dana 60 = 6k#, d70 = 7k#. At least it sounds about right.

    I thought it was a particular internal measurement inside the pumpkin in millimeters. Axle centerline to the pinion face?????????? /forums/images/graemlins/thinking.gif /forums/images/graemlins/thinking.gif /forums/images/graemlins/thinking.gif

    the renumbering is like that but I do not think the old model designation follows that logic

    metric ring gear measurement

    I doubt the number is weight related. In parts books the front D60 is often referred to as a "4500lbs axle".
