need a diff gear alternative (CRT X2)

[scarletboa]

i was hearing clicking coming from the rear diff on hard acceleration, so i opened up the diff case and after seeing no damage to the pinion or ring gear, i reshimmed and went to go run it again. the clicking was still there, so i decided to just run it until the diff is fried.

when the clicking became constant on any throttle, i picked up the truck and noticed the rear wheels were very rough when turning 1 at a time, so now i know that it is the diff internal gears that are shot. the problem is that they are aluminum gears (to save weight i guess) and if i get a new set, those gears will just wear out as well.

does anyone know a good, cheap steel internal diff gear set that will fit in the stock diff cup? i know diff case sizes vary, but aren't the internal gears pretty much the same size in all 1/8th scale diffs?

thanks in advance for any help/advice
