I use old inner races stack onto the rear pinion bearings to press them on. I did make a set of set up bearing years ago for Dana 60 so I use them first and then install the new bearings after getting the pinion depth and pinion bearing preload set up on the pinion gear. Same thing on the carrier bearing preload and back lash shims on the OEM Dana 60
The Mopar FSM call for between .013 and .015 carrier bearing preload if my memory is correct.
I'm going through a Ford Nine inch Lincoln Versiale (SP?) rear end for my 1940 Ford Tudor sedan, the on line sources I've found call fo rbetween .003 and .005 carrier bearing preload, I've got a little more than that based on setting up 8 3/4 using the Mopar FSM installation instruction, pray for me on this Ford 9 inch rear end
