diff bearings Q
 

does anyone know the size of the large diff balls (the bearings inside of the crown gear) i think mine are warn but i dont know what size to get. i think new thrust plates would be nice too. i have the inner plates replaced but my outer ones are on their way out

Why not buy new diffs altogether?
They are dirt cheap.
You can also measure the holes in the diff-gear. This should give you an indication of their size.
