hmm...is there something i can do to keep it from doing that again in the future? Upgraded diff? I tightened that thing hard and it still did it. you made it seem like a huge deal to fix it, is it really that hard/expensive to do? there isn't much there. i am going to get into racing one of these days when i get the feel of the truck a little better so i will need it to work properly. thanks bud!
