O.k. heres the deal. I have a Traxxas Nitro Sport. I was running it the other night and when I finished I noticed something was missing on the inside of the little gear attached to I think its called the clutch bell? There is the big gear and then the little gear that connect, well the little gear is now loosely hanging on the shaft that it rides on. Are these bearings that I'm missing? I don't know what the part name is that I need so I can order new ones. I'm a beginer in the hobby so don't be too harsh on me. lol Also, does anyone know where I could get a expoded view pictures of every part on this truck. I've checked Traxxas exploded views on their website but the ones they have doesn't seem to have the part I'm looking for. Any information would be greatly appreciated. Thank you.
