Today was my second time breaking one of the differentials on my Fun Factor MT2. Before, I had broken a front differential by accidently running over a bike rim. But today I was just doing some grass jumping, not going more than 10 or 15 MPH. I was also occasionaly going down the street and coming back again going pretty fast, but I didn't crash or anything. Then I heard a sound almost like the body was hitting the wheels when punching the gas, but I checked it and it wasn't. While I was checking it, I accidentaly gave a little bit of gas and noticed that the right rear wheel wasn't spinning so I shut it off and found that the differential had snapped like last time, altough this time the bar was missing to attacth to the differential ( the differential on the car not the the wheel ). I manged to find the bar, but what is causing this, is it the grass jumping, or maybe is it when I give it gas while its turning? I only need Part # GX12, like last time right?



Thanks in advance,
Andy
