ok now you would think because I race and all it would go out from that, but no. my mom took my car out and did donuts with my little brother and his friend in the car for fun. it had a brand new 10bolt in it (i messed mine up because of a blowout shortly after I bought the car and needed the cheap way out). well she didn't completely destroy it though. it's only 600 in repairs, but still. she destroyed my differential. oh well. she is paying for most of it and wouldn't pay for any of a 9inch or 12 both so I am just having a nice eaton differential put in it. I was already buying one and had it on order anyways.
