Arrma Granite Gearbox Problems? 

hey i’m kinda new to monster trucks but i think after a run like that you should take the spur out and give it a clean and check the gearbox for dirt and mud 👍

Bro u can just buy a whole diff and just install it it's really easy to do

Cuz most likely it's ur input gear went out I just got a metal diff with metal input gear and fix that problem
