i need a indestructable rear diff, please help

[blueb8llz]

so my rear diff blew out for the second time. the first time, the ring gear's teeth was chipped off. and now this time, one of the ball bearings (attaches to diff/pinion gear) broke into pieces. so the diff/pinion gear and ring gears tooth is shaved. now my plastic diff case is sorta warped and cant close tight.

can anyone suggest me the best options for me are. i think i will need a new rear diff case, maybe a aluminum diff cup, ring gear and diff/pinion gear, shims, and whatever else i may need.
oh...maybe stronger better ball bearings haha. dont even know how they even exploded like that.
thanks for all help guys!

oops forget to tell you guys. im running a emaxx 3905 with 7xl/mmm on 4s
