I've been retired for 6 years so it's been awhile since I've done a Dana 44 but as I remember backlash is .004-.008" and preload for new pinion bearings is about 20-30 in. lbs. so you could take out a .003" shim from the rear pinion race and a .005" from the front pinion bearing and see where you're at....Or does this rear end use a crush sleeve? If so, you need to make sure the pinion nut torque is at spec. (somewhere around 180-200 ft. lbs.) when the specified preload is reached. Usually it takes a new crush sleeve when setting the final preload.

I think the pattern you have now is OK, but it never hurts to try improving it!
