The present invention is directed to a method for hardening the gear pockets in a differential case through use of laser energy. As such, each gear pocket is left with a plurality of hardened tracks formed on its wall surface. The laser hardened tracks reduce the damaging effect of any wear condition experienced between the wall surface in the gear pockets and gears rotatably mounted therein.
