Perhaps the wrong bearing was installed at some point?

you can mix input and cluster gears; in fact, most gears.  diffs are
picky b/c of the complexity of the hypoid spiral bevel tooth shape.
 
it sounds like you're describing two problems: the bearing loose in
the case, and the shaft loose in the bearing.  shaft wobble as
mentioned by others is normal and even necessary, to handle tranny
alignment that isn't micron-perfect.  bearing loose in the case isn't
imho, and since the case is iron and the bearing is bearing steel,
another bearing may not fix it.
 
if the clearance isn't egregious, perhaps you could loctite the
bearing in place?
