The .015 is added to the pinion gear side, once the total amount of shims required to move the ring gear to Zero lash is obtained. The procedure to get it correct is to find the amount of shims required to slip the carrier into the axle housing to a slip (Line to Line) fit. Then you remove the shims and install the ring gear and the pinion. You then force the pinion into the ring gear while indicating the amount of travel. Then you place that amount of shims from the total amount you measured for a slip fit, on the ring gear side. Now you place the remainder of the shims on the pinion gear side PLUS the .015" required for preload. The .015" pushes the ring gear away from the pinion for backlash and provides the preload. The carrier is now a .015" press in fit into the housing. This should put the backlash within spec. From now on as you adjust backlash you remove shims from one side and move them to the other side. On a used ring and pinion shoot for .010" of backlash. If it needs to be less it will show up in the pattern.

After another look, I was also thinking .007" on the pinion. It looks close.
