Steve10gt and I run together and I have seen his problem. The dirt is actually getting into the diff inner gears and after several runs it feels very gritty when you hold it and turn the tires. It's actually so bad that the tires turn the same direction until it is taken apart and cleaned again. I helped him look and the case is sealed good so it must be getting in around the dogbones. I'm kind of curious myself as to why this is happening and if anyone else has been having this problem with the rc10gt. I've blown out diffs before but have never seen a diff that must be disassembled after every session and cleaned. This seems like a fairly serious enough problem.
