15. If installing a new differential ring gear and pinion, notice the (+) or (-) etching on both the old and new pinion, and adjust the new shim thickness
to compensate for the difference of these two figures.
^
For example, a pinion etched with m+8 (+3) requires 0.08 mm (0.003 inch) less shimming than a pinion etched "0". This means to increase
the mounting distance by the amount etched in the pinion, subtract 0.08 mm (0.003 inch) from the drive pinion position shim selected for
installation. A pinion etched m-8 (-3), requires 0.08 mm (0.003 inch) more shimming than a pinion etched "0". In this instance, add 0.08 mm
(0.003 inch) to the drive pinion position shim selected for installation to decrease the pinion mounting distance by the amount etched in the
pinion.

16. CAUTION: Follow the drive pinion bearing preload shim and drive pinion position shim assembly sequence as directed or unit failure can result.
Install the correct thickness drive pinion position shim on the pinion.
