Spec-R 牙差有冇得救?

CHing,
早輪有CHing響一兩條thread入面話,e隻牙差三幾下就掃晒牙(禾果隻都係同一命運)。
請教,有冇乜野辦法可以救招?

I don't think there are anything you can do to it......  I checked around and can't find any metal gear will fit the diff.....  I spend one hour just sanding the stupid gears and shim it so everything fit nicely.....  The pin for the outdrive eat a groove completely into the larger gear in 3 packs of battery.......
