The very reason I sold my RC10GT was the constant rebuilding of the diff.
I could never go more than 2 weekends of racing without it getting gritty.
My stepson on the other hand, has a Team Built GT that has months of racing on it and never a diff rebuild.
My HPI Pro3 can go about 3-4 weekends then I just clean and
re-lube. Everything looks fine on inspection under a magnifier.
I also use magnifier when I rebuild my car, that way I can see even smallest crack on parts. Better be safe than sorry.
Here's where I bought mine.
