Crown wheel teeth getting uprooted but not in contineous order.

(OP)
its my own observation- crown wheel teeth getting uprooted but not contineously but in random order. Oil condition was ok, no foreign material entry.Pinion teeth almost all teeth pitted. till i had seen if failure occurs it will be at least in a particular fashion, but here teeth breakage is occuring randomly. failure observed in 12 vehicles(22 ton-35 ton GVW vehicles).Teeth getting uprooted have one thing common there interferance area is slightly shifted to outward, and all other setting & bearibg condition found Ok, pininon preload was ok.Diffrential assy is in perfectly fine condition. vehicle generaly comes with a condition of diffrential noise. kindly help me to solve the problem
