take it apart, it should be obvious what the issue is.

Did you grease the gears? shim the gears? First axles I built I lightly greased them and they wore out very quickly. give the ring and pinion gears a large supply of grease and shim the pinion into the ring gear a bit(.3mm) with some shims it will make the gears last longer.

i have taken it apart and i had the diff locked and i unlocked the diff inspected the gears loaded it up with grease and put it back together and it still did it so you are saying i need to shim the little gear thanks

Might need more shims. Last week I took mine out for a test and thought I had a blown ring and pinion, but it was a rear wheel hex spinning inside the wheel...my wheel nut came a bit loose and there it went. Look at everything real close again.
